Hoang AQ, Nguyen LTH, Nguyen HD. Improper disposal of cigarette butts in a southeast Asian megacity (Hanoi, Vietnam): Pollution indexes, distribution profiles, and preliminary physicochemical characterization. THE SCIENCE OF THE TOTAL ENVIRONMENT 2024; 954:176253. [PMID: 39278483 DOI: 10.1016/j.scitotenv.2024.176253] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/25/2024] [Revised: 09/09/2024] [Accepted: 09/11/2024] [Indexed: 09/18/2024]
Abstract
Although Southeast Asia is among the largest producers and consumers of cigarettes in the world, information about environmental contamination with littered cigarette butts (CBs) in this region is very limited, especially in urban areas. In this study, we collected CBs in 58 locations of 6 categories (i.e., parks, apartments, streets, shopping malls, universities, and relic sites) in Hanoi, a megacity of Vietnam, to elucidate the occurrence, pollution levels, and physicochemical properties of this specific waste type. A total of 25,943 CBs with 86 brands from 16 origin countries was obtained, showing a density range of 0.0056 to 1.16 (mean 0.125) CB/m2 and cigarette butt pollution index (CBPI) range of 0.23 to 86.9 (mean 6.14). CB contamination levels were higher in parks, apartments, streets, and shopping malls than in universities and relic sites, but CB density and CBPI values varied greatly between locations of the same category. Generally, CB contamination levels measured in Hanoi were within a moderate range compared to other countries worldwide. Several physicochemical properties of CBs were preliminarily determined, which partly confirmed the formation of smoking-derived chemicals captured in CBs and their release potentials into surrounding environments. Further investigations are required to evaluate detailed chemical profiles, leaching behavior, and toxic effects of hazardous substances in CBs.

Andriolo U, Gonçalves G. How much does marine litter weigh? A literature review to improve monitoring, support modelling and optimize clean-up activities. ENVIRONMENTAL POLLUTION (BARKING, ESSEX : 1987) 2024; 361:124863. [PMID: 39216667 DOI: 10.1016/j.envpol.2024.124863] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/07/2024] [Revised: 08/27/2024] [Accepted: 08/28/2024] [Indexed: 09/04/2024]
Abstract
The weight of marine litter has been marginally considered in comparison to counting and categorizing items. However, weight determines litter dynamics on water and coasts, and it is an essential parameter for planning and optimizing clean-up activities. This work reviewed 80 publications that reported both the number and weight of beached macro-litter worldwide. On average, a litter item weighed 19.5 ± 20.3 g, with a median weight of 13.4 g. Plastics composed 80% by number and 51% by weight of the global litter bulk. A plastic item weighed 12.9 ± 13.8 g on average, with a median weight of 9 g. The analysis based on continents and on water bodies returned similar values, which can be used to estimate litter weight on beaches from past and future visual census surveys, and from remote sensing imagery. Overall, this work can improve litter monitoring reports and support dynamics modelling, thereby contributing for environmental protection and mitigation efforts.

Abstract
Cigarette butts (CBs) and Microplastics (MPs) have serious harmful effects on the environment and living organisms despite their small size. This research aims to investigate the abundance and pollution status of CBs and MPs in Tahtalı Dam Basin (West Anatolia, Türkiye) which is the most important drinking and irrigation water resources. Clean Environment Index (CEI) and Cigarette Butt Pollution Index (CBPI) were used to determine pollution degree of the basin. The total number of CBs were 1.478 items, the total number of MPs were 477 items/m2 in the basin. As a result of this study, MP particles weren't found in Balaban Stream. Highest number of MP particles observed in 100-250 μm (45%) size class. The most abundant MP type and colour were, fragment (54%) and white (42%), respectively. Polyethylene terephthalate (50%) was the most abundant type of polymer according to the ATR- FTIR analysis. As a result of the CEI and CBPI, the upstream stations of the stream were classified as "clean" status, while downstream sampling points of the stream and Balaban Lake coasts were classified as "extremely dirty" status. The calculated volumes of MP particulates from mining facility, agricultural and recreational activities indicate that anthropogenic factors are the most important MP source in the Tahtalı Dam Basin. This study is the first study about MP and CB pollution of the freshwater ecosystems in the region.

Abstract
Marine litter poses a significant environmental challenge in the Saronikos Gulf, Greece. Employing an integrated approach, data from both beach and underwater sites were analyzed. The average litter density on beaches was 2.61 items m-2, with plastic being the most common material, notably small polystyrene fragments and cigarette butts. The western part of the Gulf exhibited higher litter density, mainly due to surface circulation patterns. Most beaches fell short of meeting Good Environmental Status criteria for marine litter. Higher litter densities were observed in autumn. Benthic litter density decreased with depth, being 23 times higher in shallower waters, with plastic being the predominant type. This extensive study offers crucial insights into the pollution status and litter distribution in the Saronikos Gulf, contributing significantly to the global understanding of marine litter distribution on coastal ecosystems. Such information is crucial for raising awareness, informing policy decisions, and driving environmental actions.

Abstract
Spatial and temporal variations in marine litter density and composition along the Southeastern Black Sea Coast were investigated. A total of 156,371 litter items weighing 327,258.3 kg were collected. The highest frequency of litter material by number was 15,869 ± 103.88 items/m2 16 and 74.466 ± 7.23 by weight. The highest litter concentrations (77,768 items; 81,737.1 kg) were observed in autumn, mainly comprising single-use items, with plastic being the most abundant (54.05 %), followed by metal (15.69 %), and paper (10.45 %). The subcategories of plastic litter items bags, caps/lids, cigarette lighters, cosmetic packages, gloves, and plastics pieces were found to be the most abundant litter in number. According to Principal Component Analysis (PCA) and Kruskal-Wallis statistical tests (p < 0.005), significant differences in marine litter were identified among the stations and seasons. These findings offer insights for modeling studies, advocating restrictions on single-use products, and enacting legal regulations for local governance.

Abstract
Rivers are the principal route for terrestrial microplastics to reach the marine environment. The Black Sea exhibits a notable representation because it has a drainage zone almost six times the surface area and is semi-closed, meaning that microplastics tend to gather there. To mitigate MP pollution, it is necessary to identify the contamination sources and then raise public awareness. Thus, the current study focused on the MP presence in the sediment of streams running into the SE Black Sea. 594 MPs were observed in sediment samples from 16 stations along the 350 km coastline. The abundance of MP was higher, particularly in streams that pass through locations with high tourism and industrial activity levels. Detected MPs ranged between 0.1 and 5 mm, while the overall density was smaller than 1 mm. Fragments and fiber MPs were regularly detected, although the presence of films was rarely recorded. The polymer structures that were most commonly observed in the analyzed pollutants were PET and PE. The current study uncovered MP contamination in stream sediments originating from Türkiye's Eastern Black Sea basin and might be a baseline work for future inland water studies.

Spatial distribution of microplastics in a coastal upwelling region: Offshore dispersal from urban sources in the Humboldt Current System. ENVIRONMENTAL POLLUTION (BARKING, ESSEX : 1987) 2024; 343:123157. [PMID: 38142808 DOI: 10.1016/j.envpol.2023.123157] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/30/2023] [Revised: 11/15/2023] [Accepted: 12/11/2023] [Indexed: 12/26/2023]
Abstract
In coastal waters, higher concentrations of microplastics (MPs) are generally related to densely populated and industrialized areas, but intense upwelling and offshore transport in the Eastern Boundary Upwelling Systems (EBUS) may influence this pattern. The Humboldt Current System (HCS) along the coast of northern-central Chile represents a perfect model to test whether the abundance of MP at the sea surface decreases with distance from land-based sources, e.g., river mouths, harbors, and submarine wastewater outfalls. The sea surface was sampled with a manta trawl to examine the abundance, composition, and distribution of floating MPs, and Generalized Additive Mixed Models (GAMMs) were performed to examine the relationship between MP abundance (particles km-2) and the distance to putative sources. MPs were found in all 57 net tows, with an average of ⁓120,000 MP km-2 and maximum values of ⁓1,500,000 MP km-2. The composition of MPs was dominated by fragments (>50% of the total count) and over 80% of all MPs were ≥1 mm. The combined effect of the various sources, spatially concentrated in urban areas, makes it difficult to distinguish their relative contributions, but the MP composition suggested that rivers are more important sources, followed by submarine wastewater outfalls and then harbors. A significant and steep negative relationship with the "distance to source" explained 15.2% of the variance of "MP abundance", suggesting rapid offshore displacement within the HCS. This is the first study to report this pattern along the edges of the South Pacific Subtropical Gyre (SPSG), revealing that continuous offshore transport of microplastic from land-based sources is occurring over large scales and contributing to the accumulation of microplastics in the center of the SPSG. However, the findings additionally suggested that processes at meso- and submeso-spatial scales (driven by geographic and seasonal variables) are disrupting the general pattern.

Abstract
Over the years, the Black Sea has been impacted by the issue of marine litter, which poses ecological and health threats. A mid-term monitoring program initiated in 2018 assessed the abundance, density, and composition of beach litter (BL) on 40 frequently visited beaches. From 2018 to 2022, there was a significant increase in average abundance, rising by 261 %. Artificial polymer materials accounted for the majority (84 %) of the litter. Land-based sources dominated 77 % of the litter. The Clean Coast Index (CCI) categorized the beaches as "moderate" with an average value of 8.9 for the period between 2018 and 2022. However, the years 2021 and 2022, during the COVID-19 epidemic, were identified as the "dirtiest period" with 11 beaches classified as "extremely dirty" due to high domestic tourist pressure. The study demonstrates a successful combination of standard in situ visual assessment supported by unmanned aerial systems for beach litter surveys.

Abstract
This study assessed the extent of cigarette butt contamination on two urban beaches in Recife-PE (Pernambuco State, Brazil) with varying levels of use. The study considered degradation levels and evaluated whether the brands varied by time, space, and beaches use. Ten transects (1.5 m wide) and spaced 10 m apart, were delimited on the beaches investigated. Twelve collections were made between May 2021 and January 2022, and the collected cigarette butts were evaluated based on degradation level, mass, size, and brand. In total, 10,275 cigarette butts were collected on both beaches, with P1 accounting for 96.91% of the found cigarette butts. The density of cigarette butts on the beaches was directly proportional to the level of use, with 8.85 butts/m2 in P1 and 1.05 butts/m2 in P2. Eighteen brands were identified, with brand (A) being the most popular regardless of the area. Significant differences (p ≤ 0.05) were found when evaluating the amount of butts/m2; Sundays with high precipitation presented reduced values of butts; more occupied areas presented transects with higher amounts; abundance in the summer; morphometry with higher values recorded in newly discarded butts; predominance of more degraded butts and brand diversity. Despite the difference in the number of butts/m2 between the areas, it was possible to identify that their abundance is very expressive, and that the monitored beaches present a high exposure to the contaminant.

Abstract
The increasing amount of marine litter pollution and its impact on the marine environment raises global concern. This study aims to reveal the effect of streams on marine litter density and composition. A total of ten stations on the southeastern Black Sea and six stations on the Manahoz stream were seasonally surveyed. The litter density ranged between 0.838 ± 0.33 and 4.01 ± 0.55 items/m2 in the beach stations, and 0.93 ± 0.27 2.40 ± 2.18 items/m2 in the streamside stations. No significant difference was determined among the seasons for both beach and streamside (Kruskal-Wallis test, p > 0.05). On the other hand, the litter density was also similar in beach and streamside stations in the same season. The litter composition consisted of > 75% plastic. Principal component analysis and PERMANOVA determined no significant difference in litter composition among beach and streamside stations. The litter items mostly consisted of single-use items. Among them, plastic beverage containers were the most abundant litter subcategory during the study (ranging between 18.79% and 34.50%). The subcategory composition exhibited a significant difference among beach and streamside stations (ANOSIM, p < 0.05), which was mainly explained by plastic pieces, beverage containers, and foams according to SIMPER analysis. Personal protection equipment that was not reported before the COVID-19 pandemic emerged. The results of our study can be used for marine litter modeling studies and legislation for restriction or ban of most abundant single-use litter items.

Abstract
Microplastics have become a global threat to sandy beach ecosystems. To efficiently manage this threat, potential sources of microplastics should be deeply understood, which requires direct evidence as this is always a challenging task. Previous studies have reported various sources; however, the topic still needs attention to identify other potential sources of microplastics on sandy shores. Therefore, the abundance, size, color, shape, and polymer type of microplastics on nine sandy shores of the Turkish Coast of the Black Sea were examined before and after the regular tourism season to understand whether short-term tourism might be an important source. A total of 3402 microplastic items from 270 sand samples were obtained and examined. Both the abundance and the average size of the microplastics increased after the tourism season associated with the potential number of visitors and beach cleaning efforts. Further, the color, shape, and polymer type of microplastics varied between sampling times. Beach cleaning seemed to be an efficient way to minimize the adverse effect of short-term tourism influence. This study clearly identifies short-term tourism as an important source of microplastics on sandy shores and beach cleaning as an important tool to minimize microplastic abundance. The results of this study are important insights into current literature by identifying another source of microplastics on sandy shores, which should be useful for the potential management actions to reduce the harm of these global pollutants.

Abstract
Marine litter is one of the biggest environmental problems nowadays. Sinop, is located in the heart of Türkiye's Black Sea coast, has a small population, and is a popular fishing and tourist destination. In this study, marine litter amount, composition, and possible sources were investigated, and seasonal comparisons were made between in Sinop beaches. Marine litter amount was found as 0.29-7.67 items·m-2 and 3.46-49.09 g·m-2 and beaches were classified as moderate to extremely dirty. Plastics were the highest ratio (88.14-98.46 %) and "plastic pieces 2.5> <50 cm" were the major litter type. The major possible litter source was improper waste disposal (33.36 %) and litter items originated from mainly land-based sources (74.13 %). The result of this study shows that there is a significant litter problem on the coasts. The solution of this problem can be possible to take rational measures against marine litter pollution with education and management policies.

Abstract
The amount of human-origin litter in sea surface water, sediment, and beaches has been increasing for decades. Initially described in marine coastal systems in the 1960s, marine litter (ML) is nowadays commonly observed in all marine systems. There is even a gigantic island consisting of garbage in the gyre area of the Atlantic Ocean. In relation to this significant problem, ML was collected from seven stations on beaches along the Dardanelles for the first time in the period May 2017-May 2018 and was seasonally and regionally analyzed in terms of densities and weights. ML was categorized by material type (plastic, rubber, paper, etc.) and field of use (mixed packaging wastes, personal use products, fishing wastes, etc.). Total numbers and weights of ML during the study were 5751 items and 115.7 kg in an area of 15,980 m2, respectively. Density and weight of ML ranged from 0.050 to 1.182 items/m2 and from 0.446 to 78.46 g/m2, respectively. The main ML component was plastic items in terms of both density (90.95%) and weight (53.76%) according to material type. Additionally, mixed packaging wastes (MPW) were the most common ML items in terms of density (82.14%) and weight (49.38%) according to usage. According to the clean-coast index, while Kilya (St.2) and Kepez (St.5) beaches were dirty, Seddulbahir (St.1) beach was clean. The beaches in other stations were neither dirty nor clean (medium) according to the index. At the end of the study, suggestions for a regional strategy were made.

Abstract
The composition and abundance of solid waste and the effect of COVID-19 measures were studied in an inland water ecosystem in Turkey. Solid waste items were collected annually for 5 years from 2017 to 2021 from seven stations located in Borçka Dam Lake (B1-B4) and Murgul Stream (M1-M3) in the Artvin Province. The highest densities by number and weight were recorded at M3 in 2020 (5.72 items/m2) and M1 in 2020 (0.39 kg/m2), respectively. However, no significant difference in density was recorded (p < 0.05) between the years. Plastic was the most abundant waste material by number of items in all the stations with a percentage contribution varying between 25.47 and 88.89%. There was a considerable increase in medical items during the COVID-19 pandemic in 2020-2021. Nonmetric multidimensional scaling (NMDS) and ANOSIM results revealed visually and statistically significant differences in solid waste composition between the years and stations. The dissimilarity between the years was driven by plastic and medical waste. The main sources of solid waste were river transportation (22.93%), improper disposal (20.74%), aquaculture activities (16.42%), and recreational and tourism activities (14.72%). The results of our study can be a baseline for transportation models, local administrations, and non-governmental organizations. Besides, the current waste management measures in Turkey are not effective in preventing waste accumulation in inland aquatic systems such as the Borçka Dam Lake and Murgul Stream. Furthermore, these findings indicate that the COVID-19 pandemic influenced solid waste composition and increased its abundance in the study area.

Baseline Marine Litter Surveys along Vietnam Coasts Using Citizen Science Approach. SUSTAINABILITY 2022. [DOI: 10.3390/su14094919] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Indexed: 11/16/2022]
Abstract
Marine litter is a significant threat to the marine environment, human health, and the economy. In this study, beach litter surveys along Vietnamese coasts were conducted in a local context to quantify and characterize marine litter using the modified GESAMP marine litter monitoring guideline. A total of 21,754 items weighing 136,820.2 g was recorded across 14 surveys from September 2020 to January 2021. Plastic was the most abundant type of litter by both quantity (20,744 items) and weight (100,371.2 g). Fishing gear 1 (fishing plastic rope, net pieces, fishing lures and lines, hard plastic floats) and soft plastic fragments were the most frequently observed items (17.65% and 17.24%, respectively). This study not only demonstrates the abundance and composition of marine litter in Vietnam, it also provides valuable information for the implementation of appropriate preventive measures, such as the redesign of collection, reuse, and recycling programs, and informs policy and priorities, with a focus on action and investment in Vietnam. Moreover, insights from this study indicate that citizen science is a useful approach for collecting data on marine litter in Vietnam.

Abstract
Turkey is one of the major plastic pollution sources in the Mediterranean and the Black Sea. This review summarizes present information, data, and legislation on plastic pollution in Turkish aquatic ecosystems. According to results derived from reviewed studies, both macro- and microplastic pollutions were documented in Turkish aquatic ecosystems. Most of the studies on plastic pollution in Turkish waters were performed in the marine environment while only four were conducted in freshwater environments. Spatially, the majority of these studies, which were on levels in the marine environment, were conducted on the northeastern Mediterranean coasts of Turkey, especially Iskenderun and Mersin Bays. Additional studies were carried out on either the ingestion/presence/impact of microplastics by/to aquatic organisms or the entanglement of marine organisms in plastics. There were also studies assessing the microplastic content of commercial salt, and another has reported microplastic presence in traditional stuffed mussels sold in Turkish streets. Some studies were conducted on microplastic presence and/or their removal in wastewater treatment plants in Mersin, Adana, Mugla, and Istanbul cities. Macro- and microliter loading from a few Turkish rivers to the sea was also estimated. All these investigations indicate that Turkish aquatic environments have significant plastic pollution problems, which were also underlined by the legislative studies. The need for further studies in this field still exists, especially in freshwater environments.

Abstract
Microplastic (MP) contamination is a serious threat to today's marine life. Therefore, this study investigates MP ingestion in three commercial fish species (European anchovy Engraulis encrasicolus, whiting Merlangius merlangus, and red mullet Mullus barbatus) from the Turkish coast of the Black Sea. Ninety-five MPs were detected in all examined fish (371). Fiber forms were detected in the majority of cases based on the MP morphology. Polyethylene and polypropylene were the most dominant polymer type. The mean of ingested MPs was found as 0.15 ± 0.04, 0.28 ± 0.06, 0.40 ± 0.07 in anchovy, whiting and red mullet, respectively. The size of the MPs ranged from 118 μm and 4854 μm. The MP waste was detected in each species, and the highest MP amount was determined in the red mullet, which was significantly higher than European anchovy. The present study's data might be a baseline on the ecological risk assessment of MPs in the fish and future experimental studies on the fish species living in the Black Sea.

Abstract
The abundance and characteristics of benthic marine litter in the southern Black Sea shelf were demonstrated. During the surveys, 671 litter items weighing 83.93 kg were collected from the stations. The average density by number and weight were 460.70 ± 99.71 n/km2 and 80.68 ± 48.06 kg/km2. The litter density was significantly higher at 10-20 m (646.09 ± 165.63 n/km2) compared to 20-30 m (165.53 ± 81.02 n/km2) and >30 m (413.87 ± 146.59 n/km2) depth classes. Plastic (69.03%) was the most abundant material by number, followed by textile (20.94%) and metal (5.68%). The litter composition differed between the no-trawl zone and trawl ground. Our results indicate that more detailed research is needed to understand the interaction of various factors influencing transportation and accumulation of marine litter in the Black Sea.

Abstract
Ingestion and egestion of microplastics by copepods in the Black Sea was assessed for the first time. Composition and concentration of microplastics in the water column was also evaluated. Samples were collected from three stations (river mouth, coastal and open water) in the Southeastern Black Sea over the course of one year. Microplastic concentration in the water column ranged between 0.12 and 7.62 mp·m-3 (mean 2.04 ± 1.05 mp·m-3) with significantly higher concentrations in the river mouth. The most common types of microplastics were fibres, followed by films and fragments. A total of 11 colours of microplastics were found, being blue the most common colour. Analysis of 1126 C. euxinus and 1065 A. clausi, resulted in 26 and 9 microplastics being detected, respectively. This resulted in a microplastic ingestion of 0.024 ± 0.020 mp. Calanus-1 and 0.008 ± 0.006 mp. Acartia-1. Analysis of 351 faecal pellets, resulted 4 microplastics being found. The average size of ingested microplastics was greater in C. euxinus (0.100 mm ± 0.153 mm) than in A. clausi (0.062 mm ± 0.056 mm). Size of ingested microplastics was in the size range of natural preys of these copepods. Fragments were the most common type of ingested microplastics, followed by films and fibres. The colour of ingested particles was black, blue and red. Our results show that the copepods and the pelagic environment of the Black Sea are contaminated by microplastics. Critical functions of zooplankton in this degraded ecosystem are under risk and zooplankton are likely to act as a vector for the transfer of microplastics and associated toxic chemicals to upper trophic levels including humans in the Black Sea.

Abstract
In this study, the abundance, and characteristics of the microplastics on the southern coast of the Black Sea were assessed. More than 70% of the detected microplastics were smaller than 2.5 mm and mostly consisted of fibers and fragments. The average microplastic abundance in the beach sediment and seawater were 64.06 ± 8.95 particles/kg and 18.68 ± 3.01 particles/m3, respectively. The western coast of the study area (Marmara region) was the most polluted area, and a spatially significant difference was determined in terms of abundance. The composition in the beach sediment (particles/kg) was dominated by styrene acrylonitrile copolymer (SAC) (40.53%), polyethylene terephthalate (PET) (38.75%), and polyethylene (PE) (6.91%), whereas the seawater (particles/m3) was dominated by PET (57.26%), PE (13.52%), and polypropylene PP (11.24%). The results of our study can be a baseline for environmental modeling studies and experimental studies on the marine organisms inhabiting the Black Sea.

Abstract
The Aegean Sea is one of the most contaminated by marine litter (ML) in the World. In this study, the Turkish Aegean Region was evaluated in light of the sources, abundance and composition of ML along Çakalburnu Lagoon coast. Macroscopic ML with > 3 cm was collected and separated into composition and sources categories. ML abundance was calculated by its density in items/m2 (Mean ± SD). Beach cleanliness was evaluated according to Clean-Coast Index (CCI). Seasonality was found as factor for ML composition, sources and abundance at Çakalburnu coast. Plastic was the most abundant material, followed by unidentifiable items. The major sources of ML were mixed packaging, domestic and fisheries activities. The mean ML density was 0.64 ± 0.09 items/m2. Çakalburnu coast was classified as dirty during all seasons. Therefore, ML contamination on Çakalburnu coast represent a potential threat to coastal and marine environments. Thus, the present study can serve as a base for the elaboration of mitigating actions urgently needed at Çakalburnu Lagoon.

Abstract
Time-series datasets showing the gradual conformational change in the status and characteristics of microplastics (MP) in marine waters are needed to protect vulnerable marine ecosystems. In this study, the abundance, spatiotemporal distribution, polymer composition, size, and shapes of the MP in the seawater sampled from 0.5 (station-1), 2.5 (station-2), and 5 (station-3) miles off the coast of the southeastern Black Sea between 2009 and 2020 were investigated. The abundance of the MP ranged from 0.181 to 0.944 m-3. The amounts of MP in the stations, from the greatest to the smallest, were 0.65 MP m-3 (2), 0.45 MP m-3 (1), 0.29 MP m-3 (3). Thirteen types of polymers were detected by FTIR, the most abundant types of which were polyethylene (44.9%) and polyethylene terephthalate (25.3%). Sizes of MP ranged from 118 to 4998 μm, 50% being smaller than 2000 μm. The most dominant shape of the MPs was fragments (56.3%). Abundance did not show significant spatiotemporal changes. Periodical data presented herein may represent a remarkable projection and create a baseline for the ecosystem's future functioning and pollution research in the Black Sea.

Abstract
Stranded marine debris (MD) has become a hot topic on Bali Island because it threatens coastal tourism sustainability. This study aims to investigate the spatiotemporal abundance and characteristics of MD on 14 touristic beaches in Bali Island. Sampling is carried out twice every season by adapting methods from NOAA's MD program. We found that the average MD abundance and weight were 0.356 ± 0.366 items/m2 and 4.057 ± 3.892 g/m2, respectively. Plastic dominated the MD based on abundance (86.9%) and weight (40.1%). Plastic bags, straws, and plastic cups are the most common items among plastics. The MD is originated from Indonesia and is dominated by land-based sources. The beaches are categorized as dirty in the rainy seasons and clean in the dry seasons. Statistically, the MD based on abundance, weight, category, source, and level of cleanliness varied significantly between seasons.

Chuturkova R, Simeonova A. Sources of marine litter along the Bulgarian Black Sea coast: Identification, scoring and contribution. MARINE POLLUTION BULLETIN 2021; 173:113119. [PMID: 34763182 DOI: 10.1016/j.marpolbul.2021.113119] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/12/2021] [Revised: 11/01/2021] [Accepted: 11/02/2021] [Indexed: 05/16/2023]
Abstract
The sources of marine litter (ML) pollution along the Bulgarian Black Sea coast in 2019 were identified and categorized to: Public litter, Fishing, Shipping, Sanitary and sewage, Fly tipped, Medical and Non-sourced, following Veiga et al., 2016 approach. Largest was the contribution of Public litter - 48.3% and Non-sourced - 38.5% of the total. Most Public litter items were attributed to recreational activities - 82.9% Public litter Recreation and less to Public litter Smoking-related - 17.1%. Regarding to Non-sourced, the following sub-categories seemed to contribute clearly more: Land (run off) - 8.79% and Tourism beach users - 8.58%. Considerably lower was the contribution of Fishing, Offshore and Shipping. None of the items were attributed to Sewage related. The ML pollution on the individual beaches (10 sites) exhibited largest contribution of Public litter with most significant input of Public litter Recreation, varying from 65.9 to 86.7% between beaches.

Abundance and Temporal Distribution of Beach Litter on the Coast of Ceuta (North Africa, Gibraltar Strait). WATER 2021.

Abstract
Twelve beaches located in Ceuta (Spain) were studied from February to April 2019 to assess litter amounts (expressed as number of items), categories and temporal distribution. At each beach, three surveys were conducted, i.e., one per month (i.e., 36 in total). Selected beaches covered urban (7), rural (2) and remote (3) bathing areas. Plastic represented the dominant material, i.e., 35.2% of all debris, followed by glass (18.2%), pottery/ceramics (14.6%), wood (11.4%), metal (11.4%), paper/cardboard (4.8%), cloth (3.5%), rubber (0.7%), organic (0.3%) and other materials (0.1%). The Clean Coast Index was calculated to classify beaches in five categories for evaluating the cleanliness level of the coast observed at each survey: “Very Clean” (7 surveys), “Clean” (10), “Moderately Dirty” (8), “Dirty” (2) and “Extremely Dirty” (9). Litter occurrence was assessed by the Litter Grade methodology, which allowed to classify beaches in four grades: “A”: very good (0); “B”: good (4); “C”: fair (7); and “D”: poor (25). In a few surveys, some beaches were considered “good”, but their management should not be ignored because in other surveys those beaches reached fair and poor scores. Several potentially harmful litter items were related to beach users. Severe eastern storms removed litter at many of the beaches investigated and favored accumulation at others. Data analysis shows significant differences in litter abundance with respect to site, beach typology and the presence of cleaning operations but no important differences between the studied months. Rural beaches recorded the most litter, followed by urban and remote beaches. All beaches require immediate and more appropriate management actions to improve their environmental status.

Abstract
This research on the species diversity of fouling diatoms and cyanobacteria on different polymer materials and carried out from August to November 2020 in Karantinnaya Bay of the Black Sea. There were 75 taxa of diatoms and 24 of cyanobacteria. The maximum diatoms (31 species) were on the biodegradable bag and cyanobacteria (16) on the plastic bottle. A little known for the Black Sea species of diatoms and cyanobacteria were recorded. The diatoms Cylindrotheca closterium, Nitzschia sigma, and cyanobacteria Spirulina subsalsa were found on all samples. A tendency to increase diversity and species similarity was revealed during long-term exposition of substrates. To the end of exposition, the periphyton communities became indifferent to the type of substrate and acquired signs of natural fouling, which was observed especially for cyanobacteria. The occurrence and species similarity of diatoms and cyanobacteria communities on different substrates are discussed.

Spatiotemporal variations in anthropogenic marine litter pollution along the northeast beaches of India. ENVIRONMENTAL POLLUTION (BARKING, ESSEX : 1987) 2021; 280:116954.

Abstract
Marine litter is widely distributed in marine environments and has been a severe concern worldwide, due to the disposal of waste from diverse sources. The severity of this threat has garnered increasing attention in India over the last decade, but the full consequences of this pollution are yet to be quantified. To estimate the spatiotemporal distribution, composition and beach quality of marine litter pollution, 17 beaches along the Hooghly estuary, a part of the Gangetic delta was studied. Marine litter was collected from 100 m long transects during two seasons (monsoon and post-monsoon). The OSPAR monitoring standard was applied to the 16,597 litter items collected, then grouped under 6 types and 44 categories. In terms of number, litter abundance was higher during monsoon (1.10 ± 0.39 items/m2) than that of post-monsoon (0.86 ± 0.32 items/m2). Most of the beaches were categorized as low cleanliness as computed by the general index and clean coast index and the good for the pellet pollution index. Hazardous litter constituted 6.5% of the total collected litter items. The model prediction revealed that the influence of high discharge from Hooghly, Rasulpur and Subarnarekha River carried enormous anthropogenic litter to the northeast beaches. The litter flux decreases with an increase in distance from the shore, and act as a sink to the sea-floor. The results denote that the distribution and typology of marine litter were representatives of household, tourism and fishing, which in turn highlights the need for better regional litter management measures. Suggested management practices include source reduction, mitigation, management of beach environment and change in littering behaviour through environmental education.

Abstract
Six marine litter standing stock surveys were carried out to determine the influence of monsoon on the temporal abundance and composition of macro-litter in Mkomani beach, Mombasa Kenya. Foam (0.073 items m-2) and plastic (0.042 items m-2) fragments had the highest densities. The brand audit indicated that 66.9% of branded marine litter was of Kenyan origin. Food product packaging contributed 78.4% of the branded litter with PET bottles being the most abundant type of packaging (48.2%). Foreign products contributed 35.6% of branded marine litter during South East Monsoon (SEM) whereas only 11.7% during North-East Monsoon (NEM). Worth noting, PET packaging dominated during SEM (53.6%) compared to NEM (20.2%). Mkomani beach could be considered "extremely dirty" with a Clean-Coast Index greater than 20. The study concludes that monsoons influences litter diversity, richness and evenness.

THE SCIENCE OF THE TOTAL ENVIRONMENT 2021; 769:144864. [PMID: 33477037 DOI: 10.1016/j.scitotenv.2020.144864] [Citation(s) in RCA: 23] [Impact Index Per Article: 7.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/12/2020] [Revised: 12/17/2020] [Accepted: 12/19/2020] [Indexed: 06/12/2023]
Abstract
Cigarette butts (CBs) are hazardous wastes usually littered by smokers and are of the prevalence wastes in the environment. Although various studies have been done regarding the quantity of CBs on the coast, few studies have been conducted on its density and distribution in urban areas. Therefore, the objective of this study was to assess the quantity and distribution of CBs in urban areas to define an index to convert the results into comparable data in various conditions and cities. The data were obtained by visual surveys using field CB counts in the summer of 2019 in the city of Qazvin, Iran. Cigarette butt pollution index (CBPI) was defined by considering CB density, weather conditions, urban characteristics including the structure of the walkways, and distance from groundwater. The findings indicated that the average cigarette butts density in urban areas were found to be in range of 0.01 and 0.51. Spatial variation of CB was observed in the city due to urban characteristics like land use, differences in municipal services, and population density. The CBPI index calculated for a park showed the highest number whereas an administrative (official) area had the lowest CBPI of 0.15. Given the significant pollution of the city studied with CBs and the proper performance of CBPI in classifying various parts of the city, using this method and index can be a good way to assess CBs in the streets of most of the cities.

Abstract
The eastern Mediterranean is a region that has been relatively understudied with regards to anthropogenic marine litter despite potential for environmental and social costs. Here, coastal marine litter accumulation was assessed at eight beach locations along the coast of Northern Cyprus. Monthly surveys were performed between January 2017 and January 2019. All items ≥ 2.5 cm in diameter within the same 250 m2 plot were collected and processed. A total of 59,556 separate items were collected with a total mass of 697 kg. At the worst affected site (Ronnas Bay) litter accumulation averaged 1114 items and 11.9 kg per month. Plastic and polystyrene litter accounted for 82% (622.71 kg) of all litter types by mass and 96% (57,231) by frequency. Plastic bags, plastic pieces, drinks containers, caps/lids were the four most abundant forms of plastic by mass and by frequency. This suggests dumping/poor domestic waste governance as the main driver of marine litter in the region.

Abstract
This study is the first study to determine beach litter pollution in the Eastern Mediterranean region of Turkey. The pollution of beach litter were seasonally evaluated in a selected beach in the East Mediterranean Sea between August 2019 and April 2020. Beach litter survey was carried out seasonally according to 'Guidance on Monitoring of Marine Litter in European Seas' published by European Marine Strategy Framework Directive Technical Subgroup on Marine Litter. During the study, a total of 10.717 items and 229.29 kg were collected. The average litter abundance was 2.679 ± 0.418 items/m2 and 57.326 ± 7.165 g/m2. The results indicated that the most common type of litter were plastic and cloth/textile (84%) followed by paper/cardboard (56%), the unidentifiable (51%). Litter density showed significant seasonal differences with the highest in summer (P < 0.05). Akyatan beach was classified as extremely dirty according to Clean Coast Index. It was observed that the litter in the region averagely consisted mostly of mixed packaging litter (23.75%), domestic litter (20%) and unclassified litter (16.2%) items. Our results show that the coast of Akyatan Lagoon exposed to a significant amount of marine litter pollution originated from land-based sources. This study provides further evidence that there is a significant litter pollution in the East Mediterranean Sea and that the main component are plastics, which pose a great treat to Mediterranean Sea environment.

Abstract
Seasonal distribution of Marine Litter (ML) on Santos beaches was assessed using a citizen science strategy. Plastics and cigarette butts (CB) were the dominant items in all sampling campaigns. Seasonal distribution did not result in significant differences for most items. Plastic and CB amounts were high in summer compared to autumn. For all sampled sites the presence of beach users influenced ML densities. However, results showed that some sites presented an additional influence of local hydrodynamic. Moderate amounts of hazardous items including metal, glass, CB, sanitary waste and plastic tubes used to pack and market illicit drugs represented between 20.8 and 31% of all ML over the seasons. The beaches of Santos were classified as dirty in autumn and spring and as extremely dirty in winter and summer. These findings can serve as a baseline to support mitigating actions by public authorities and start monitoring programs of ML not only in Santos but also in other urbanized beaches.

Abstract
Littered waste is a severe environmental problem. Although there have been many studies on wastes littered in the environments like beaches and seas, there is insufficient information on littered wastes in the urban settings. In this research, employing visual survey by the field litter counts method, littered wastes in six urban land uses in Qazvin, Iran were studied. The results showed that administrative and recreational land uses, by an average of 5.22 and 9.59 items per 100 m, respectively, had the lowest pollution, while low-density commercial land use had the maximum pollution by 185.96 items per 100 m. Urban littered waste ratios were not the same in various land uses: cigarette waste and paper and cardboard accounted for higher than 80% of the whole littered wastes in most studied land uses. The cigarette butt was also the most frequently litter in the city. In terms of environmental status, administrative and recreational areas can be defined as places with good conditions, while low-density commercial land use had bad conditions. Consequently, urban land use was acknowledged as a significant factor in the density of littered waste. More attention to cleaning the commercial land use to reduce the density of littered waste, and also finding methods to decrease littering waste by citizens, is a need in urban environment.

Abstract
This study is focused on delivery and fate of floating marine litter (FML) carried by rivers to coastal sea. We examine a large flooding event which happened in the northeastern part of the Black Sea in October 2018. A high resolution circulation model coupled with a Lagrangian particle model is applied to simulate transport of riverine FML in the coastal sea. During this flood multiple river plumes in the study area coalesced into one stripe of freshened water which occupied large segment of coastal sea along the shoreline. Riverine FML was transported within this stripe far off its sources in river mouths and remained arrested near the shore. As a result, approximately half of the discharged FML was washed ashore by the Stokes drift. FML, which remained in the sea, accumulated at convergence lines associated with large salinity gradients at the fronts between the river plumes and the ambient sea.

Abstract
Although marine plastic litter has been recognized as a global problem, there are insufficient data on the extent of plastic pollution in the Black Sea. The results from this pilot study of the floating marine litter and microplastics along the Bulgarian Black Sea coast revealed high quantities of floating litter (60.3-93.8 items.km-2). The microplastic concentrations (1.14 × 104-1.91 × 105 items.km-2, 0.33-490.52 g.km-2) were on average lower than those found in other parts of the Black Sea, the Baltic Sea, and the Mediterranean Sea, although the observed ranges were similar. Further studies are needed to elaborate the extent and spatial distribution of this type of pollution in the Black Sea basin.

Abstract
The composition and metabolic properties of cultivable heterotrophic aerobic bacteria, the levels of indicator bacteria, and physicochemical parameters were investigated in the seawater samples collected from 20 stations in coastal areas of the eastern part of the Black Sea, Turkey, between May 2017 and February 2018. The levels of indicator bacteria were detected above the national limit values during the study period. Thirty-five different bacterium species were identified. Enterobacteriaceae was recorded as the most dominant family (34.2%), and Gammaproteobacteria was recorded as the most dominant class (74.2%). Bacteriological threats on human and ecosystem health were determined in coastal areas of the Southeastern Black Sea. The determination of the high levels of indicator bacteria, the high ratio of fecal coliform/fecal streptococci (FC/FS ratio), and pathogenic bacteria regarding human and ecosystem health showed that these coastal areas under the influences of terrestrial and human-sourced bacteriological pollution. This study has contributed to the increase of knowledge of understanding the protection and rehabilitation ways of the Black Sea coastal regions against land-based pollution sources considering the interdependent structure of all Black Sea countries. Coastal areas are accepted as the most fragile part of the marine environments and our findings showed the potential bacteriological risks in coastal areas of the Southeastern Black Sea as an important example. Serious precautions should be taken for the protection in this area and such coastal ecosystems to prevent hazardous problems.

Abstract
The distribution and accumulation of floating marine debris in the Black Sea during the last few decades are analysed by the help of numerical modelling. An approach based on a mesoscale circulation model combined with a particle tracking model is applied. It is established that the litter distribution is nearly independent of the source location and is mainly controlled by the basin circulation system. The western gyre predominantly accumulates floating debris in summer. After the integration of the main cyclonic current in winter, the debris in the inner basin moves east. Retention zones along the south-western coast persist in time. The mean particle stranding time is estimated at about 200 days. Accumulation zones along the south-eastern and eastern coast are abundant in summer, and then move further northeast and north. Simulations demonstrate an increasing litter accumulation in summer on the North Western Shelf and shelf break.

Abstract
Long-term monitoring of marine litter composition and density has been conducted between 2009 and 2018 on eleven beaches of Trabzon city located on the south-eastern Black Sea coast in Turkey. All unnatural litter items were collected from randomly selected transects on the beaches. A total of litter items 4138 in number and 108.75 kg in weight were collected during the study. The highest litter density was 22.00 items/m2 which is categorized as extremely dirty by Clean-Coast Index. The ANOVA results revealed that there was a significant difference in density between years (p< 0.05). However, no significant difference was found between stations, substratum and whether the station is located on a river mouth (p> 0.05). Plastic (79.69%) was the most commonly found litter followed by metal (7.37%) and glass (5.58%). The main source of the litter items was found to be river transportation (21.96%).

Abstract
Litters are the most pollutants in progress of the interests in marine environments. Macro litter samples were collected from 66 stations to estimate litter contribution from pleasure crafts along bays of the most Turkish touristic coasts (Antalya-Muğla) by the divers in June/July 2019. Average abundance and weight were 19 items/km2 and 18 kg/km2, respectively. The most abundant litter was plastics and the most contributors in weight were metals, followed by glass/ceramics. Abundance of the litters increased with number of pleasure crafts in active in summer. Pleasure crafts contributed most abundantly with the personal wares to the total litter, particularly in the coasts of Muğla. Litters were differentiated with interaction of region × bottom depths. The litter composition and abundance were different between region of Antalya in active mostly by tour boats and region of Muğla by private yachts. The litter types were however correlated with sea surface temperature.

Abstract
In this study, transport and possible accumulation of microplastic marine litter in enclosed coastal waters are modeled numerically. The model is applied to the Fethiye Inner Bay, located in Fethiye-Göcek Specially Protected Area. In modeling studies, three dimensional coastal hydrodynamics, transport and water quality numerical model HYDROTAM-3D was used. The current climate was prepared by modeling long-term circulation patterns due to wind, wave and density stratifications. Following the hydrodynamic studies, the advection and diffusion of 3 mm size polystyrene particles by the coastal currents in the surface waters of Fethiye Inner Bay were simulated. The coastal regions where the microplastic pollution will be concentrated and transported were determined by the modeling scenarios. It has been found that microplastic accumulation is expected in the southwest and east coastal waters of the Fethiye Inner Bay. The results of the model will contribute to the databases for sustainable protection of the marine environments.

Abstract
Marine debris, defined as any persistent manufactured or processed solid material discarded, disposed of or abandoned in the marine and coastal environment, has been highlighted as a contaminant of global environmental and economic concern. The five main categories of marine debris comprise of plastic, paper, metal, textile, glass and rubber. Plastics is recognised as the major constituent of marine debris, representing between 50% and 90% of the total marine debris found globally. Between 4.8 and 12.7 million metric tonnes of consumer plastics end up in the world oceans annually, resulting in the presence of more than 100 million particles of macroplastics in only 12 regional seas worldwide, and with 51 trillion particles of microplastic floating on the ocean surface globally. The impacts of marine debris can be branched out into three categories; injury to or death of marine organisms, harm to marine environment and effects on human health and economy. Marine mammals often accidentally ingest marine debris because of its appearance that can easily be mistaken as food. Moreover, floating plastics may act as vehicles for chemicals and/or environmental contaminants, which may be absorbed on to their surface during their use and permanence into the environment. Additionally, floating plastics is a potential vector for the introduction of invasive species that get attached to it, into the marine environment. In addition, human beings are not excluded from the impact of marine debris as they become exposed to microplastics through seafood consumption. Moreover, landscape degradation owing to debris accumulation is an eyesore and aesthetically unpleasant, thus resulting in decreased tourism and subsequent income loss. There are a wide range of initiatives that have been taken to tackle the issue of marine debris. They may involve manual removal of marine debris from coastal and aquatic environment in form of programmes and projects organised, such as beach clean-ups by scientific communities, non-governmental organizations and the removal of marine litter from Europe's four regional seas, respectively. Other initiatives focus on assessment, reduction, prevention and management of marine debris under the umbrella of international (the United Nations Environment Programme/Mediterranean Action Plan, the Oslo/Paris Convention) and regional organisations - that is, the Helsinki Commission. There are also a number of international conventions and national regulations that encourage mitigation and management of marine debris. However, it is argued that these initiatives are short-term unsustainable solutions and the long-term sustainable solution would be adoption of circular economy. Similarly, four of the sustainable developmental goals have targets that promote mitigation of marine debris by efficient waste management and practice of 3R. As evident by the Ad Hoc Expert Group on Marine Litter and Microplastics meeting, tackling the marine debris crisis is not a straightforward, one-size-fits-all solution, but rather an integrated and continuous effort required at local, regional and global level.

Abstract
Quantitative assessment of marine litter (ML) along the Bulgarian Black Sea coastline was presented. ML surveys were conducted every season in a total of 8 beach monitoring sites during 2015-2016. Eight main categories of material were determined, based on standard OSPAR monitoring protocol. Annual accumulation of 19,805 nos. was recorded. The highest was the quantity of items related to artificial polymer materials category - 16,690 nos. The most dominant in this category were cigarette butts and filters - 4496 nos., followed by plastic caps/lids drinks - 1413 nos. and cups and cup lids - 1194 nos. The highest was the abundance of most of the litter during the summer period, related to the increased number of beach visitors, numerous temporarily working fast - food eateries, some big and small restaurants and cafes in close proximity to the beaches, as well as fishing, wild camping, etc. The contribution of ML types to the coastal pollution, presented by number and weight of items was determined. The highest was the contribution (by number) of cigarette butts and filters - 29.7%, followed by plastic caps/lids of beverages - 9.4%; plastic cups and cup lids - 7.9%, etc. According to the weight drink bottles > 5 L exhibited highest percentage - 30.7%, followed by shopping bags incl. pieces - 15.5% and drink bottles ≤ 0.5 L - 13.2%. The ML accumulation, presented by number and weight gives more detailed information about litter characteristics, the levels of coastal pollution and improves ML management.

Abstract
This study was aimed at monitoring beach litter using an unmanned aerial vehicle (UAV) in the coastal city of Fuzhou, China. The data analysis shows that the optical images obtained by digital cameras on the UAV can help to identify and monitor beach litter using remote sensing and GIS technologies. The threshold method can effectively segment the UAV image in the beach area. It is useful for quickly monitoring the distribution of beach litter in the area of interest, and hence it can help to provide effective technical support for the investigation and assessment of coastal beach litter.

Abstract
Given the complexity of the dynamics in litter reposition, our objective was modeling the possible main and interaction effects of tidal oscillations, seasons of the year and the moon phases over the solid waste in Santos beaches. A total of 80 collections were carried out using quadrat sampling, from which we classified, counted and weighed all residue items. We fitted mixed Hurdle models to the output datasets and performed hypotheses tests based on this framework. We found plastic to be the most abundant residue in all seasons, moon phases and tides, followed by Styrofoam and wood. Our models suggest the strongest effect was due to seasonal variations, which, in turn, may be related to different human activities. Although the dynamics of different components showed independency of all interaction structures, plastics depended on the interaction of tide and season, whose impact over estuarine life and ecosystem services shall be further investigated.

Abstract
A monitoring program was carried out in autumn 2015 along the Mediterranean coast of Morocco, at sites including urban, village and remote/rural beaches. Artificial Polymer Materials (APM) represented 70.64% of all collected items and included plastic (16 categories), foamed plastic (3) and other APM materials (2). Plastic items represented the dominant debris with 5356 items, i.e. 94.53% of all APM debris, foamed plastics presented 191 items (i.e. 3.37%) and other APM summed 119 items, i.e. 2.1% of all APM. Urban areas presented 49.63% of all APM recollected items with cigarette butts representing 32% of total APM items. Village areas presented 40.43% of total APM recollected items with cigarette butts representing 14.1%. Remote and rural beaches recorded 9.94% of total APM items and no cigarette butts were observed. Despite the efforts of local administrations, which introduced litter bins and enforced mechanical and manual cleaning operations, debris were essentially related to beachgoers.
