THE SCIENCE OF THE TOTAL ENVIRONMENT 2024; 908:168244. [PMID: 37923271 DOI: 10.1016/j.scitotenv.2023.168244] [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: 07/25/2023] [Revised: 10/04/2023] [Accepted: 10/29/2023] [Indexed: 11/07/2023]
Abstract
The ubiquitous and persistent presence of microplastics (MPs) in aquatic and terrestrial ecosystems has raised global concerns due to their detrimental effects on human health and the natural environment. These minuscule plastic fragments not only threaten biodiversity but also serve as vectors for contaminants, absorbing organic and inorganic pollutants, thereby causing a range of health and environmental issues. This review provides an overview of microplastics and their effects. This work highlights available analytical techniques for detecting and characterizing microplastics in different environmental matrices, assessing their advantages and limitations. Additionally, this review explores innovative remediation approaches, such as microbial degradation and other advanced methods, offering promising prospects for combatting microplastic accumulation in contaminated environments. The focus on environmentally-friendly technologies, such as the use of microorganisms and enzymes for microplastic degradation, underscores the importance of sustainable solutions in plastic pollution management. In conclusion, this article not only deepens our understanding of the microplastic issue and its impact but also advocates for the urgent need to develop and implement effective strategies to mitigate this critical environmental challenge. In this context, the crucial role of advanced technologies, like quantitative Nuclear Magnetic Resonance spectroscopy (qNMR), as promising tools for rapid and efficient microplastic detection, is emphasized. Furthermore, the potential of the enzyme PETase (polyethylene terephthalate esterase) in microplastic degradation is examined, aiming to address the growing plastic pollution, particularly in saline environments like oceanic ecosystems. These innovations offer hope for effectively addressing microplastic accumulation in contaminated environments and minimizing its adverse impacts.

Abstract
Nehir, haliç ve lagünler, karasal ve deniz ekosistemleri arasında bağlantıyı sağlarken, tıpkı diğer kirleticilerde olduğu gibi sediment yapılarında da mikroplastik kirliliği hakkında kapsamlı bir profil ortaya koymaktadır. Bu çalışmada, Küçükçekmece Lagünü’nün üç farklı sucul alanından (deniz, kanal ve göl) alınan sediment örneklerinde mikroplastik bolluğu ve karakterizasyonunun belirlenmesi amaçlanmıştır. Bu kapsamda, lagünde belirlenen 5 istasyondan 12 aylık (Mart 2019 – Şubat 2020) sediment örnekleri alınmıştır. Mikroplastik ön işlemlerine tabi tutulan sediment örneklerinde, stereomikroskop ile mikroplastik bolluğu sayımı ve kategorizasyonu (boyut, tip ve renk) yapılmıştır. Ortalama mikroplastik bolluğu 2922,32±517,35 MP/kg olarak belirlenmiş olup, tespit edilen ortalama mikroplastik bolluğu değeri, ülkemizde daha önce yapılmış benzer çalışmalara kıyasla 2,4 kat daha yüksek bulunmuştur. Liflerin (%59) baskın mikroplastik tipi olduğu, baskın mikroplastik renginin siyah (%42) olduğu ve MP boyutlarının %50’sinin 1-100 μm arasında olduğu belirlenmiştir. Mevsimsel mikroplastik dağılımı irdelendiğinde ise, en yüksek bolluk değerlerinin yağışlı sezon olan kış aylarında olduğu tespit edilmiştir. Çalışma alanında en yüksek ortalama mikroplastik bolluğuna sahip L1 istasyonu, Küçükçekmece Lagünü Bağlantı Alanı temsil etmekte olup, lagündeki tüm antropojenik baskıların hissedildiği istasyon olarak ortaya çıkmaktadır. Bu çalışma, dünyanın diğer bölgelerindeki benzer sediment alanları için mikroplastik bolluğu ve dağılımı hakkında temsili veriler sağlamayı amaçlamaktadır.

Binational survey using Mytilus galloprovincialis as a bioindicator of microplastic pollution: Insights into chemical analysis and potential risk on humans. THE SCIENCE OF THE TOTAL ENVIRONMENT 2023; 870:161894.

Abstract
Microplastic (MP) contamination in edible mussels has raised concerns due to their potential risk to human health. Aiming to provide valuable insights regarding the occurrence, physicochemical characteristics, and human health implications of MP contamination, in the present study, two nationwide surveys of MP contamination in mussels (Mytilus galloprovincialis) were conducted in Morocco and Tunisia. The results indicated that MP frequency ranged from 79 % to 100 % in all the analyzed samples. The highest MP density was detected in mussels from Morocco (gills "GI": 1.88 MPs/g ww-1; digestive glands "DG": 0.92 MPs/g ww-1) compared to mussels of Tunisia (GI: 1.47 MPs g- 1; DG: 0.79 MPs g- 1). No significant differences in MP density were found between the two organs (GI and DG) for both countries. MPs were predominantly blue and black fibers, and smaller than 1000 μm. Seven polymeric types were identified, of which PET, PP, and PE were the most abundant, accounting for >87 % of all samples. Scanning Electron Microscopy (SEM) coupled with Energy dispersive X-ray (EDX) showed that most MPs have noticeable signs of weathering and inorganic components on their surface. The highest MP daily intake was found in children, while the lowest was estimated in women and men. Moreover, the annual dietary exposure of MPs through mussel consumption was estimated to be 1262.17 MPs/year in Morocco and 78.18 MPs/year in Tunisia. The potential risk assessment of MPs in mussels based on the polymer hazard index (PHI) was estimated in the high-risk levels, implying that MPs may pose health risks to humans. Overall, this research suggests that the consumption of mussels represents a considerable MP exposure route for the Moroccan and Tunisian populations.

Abstract
Mismanaged plastic waste interacts with secondary environmental pollutants, potentially aggravating their impact on ecosystems and human health. Here we characterized the natural and artificial radionuclides in polyethylene terephthalate (PET) bottles collected from the industrial littoral discharge of a phosphate fertilizer plant. The activity concentrations in littered bottles ranged from 0.47 (208Tl) to 12.70 Bq·kg-1 (226Ra), with a mean value of 5.30 Bq·kg-1. All the human health risk assessment indices (annual intake, annual effective dose, and excess lifetime cancer risk) estimated for radionuclides associated with ingestion and inhalation of microplastics were below international safety limits. Our results demonstrated that PET can be loaded with natural and artificial radionuclides, and potentially act as a carrier to transfer radionuclides to humans, posing a new potential health risk. Increased use, mismanagement and fragmentation of plastic waste, and continued interaction of plastic waste with radioelements may lead to enhanced radiation exposure in the future.

Abstract
The marine weathering of microplastics is spectrally characterized by the appearance of new bands that disturb our understanding of the information carried by the spectra. Yet, no explanation has been provided on the chemical origin of these new bands. Thus, the main objective of this work was to identify the origins of these additional bands. To this end, 4042 spectra of poly (styrene), poly(ethylene) and poly(propylene) microplastics collected in the Mediterranean Sea, were analysed using principal component analysis. The results showed that the spectral variability was mainly related to only three processes: chemical ageing, organic and inorganic fouling. These processes probably differ from one polymer family to another due to surface affinities. This work has also led to the proposal of two new polymer indices that could be used to monitor the intensity of (bio)fouling. Finally, the development of advanced analyses could also provide information on the nature of the plastisphere.
