Fard NJH, Jahedi F, Turner A. Microplastics and nanoplastics in tea: Sources, characteristics and potential impacts. Food Chem 2025; 466:142111. [PMID: 39608112 DOI: 10.1016/j.foodchem.2024.142111] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2024] [Revised: 11/14/2024] [Accepted: 11/15/2024] [Indexed: 11/30/2024]
Abstract
Recent scientific studies have raised concerns about the presence and potential impacts of microplastics and nanoplastics (MNPs) in tea-based drinks. This review critically examines publications relating to MNPs in tea, with focus on the type of sample involved, methods and techniques employed to isolate and identify MNPs, and the main qualitative and quantitative findings. Sources of MNPs in tea include production water, plastic packaging and contaminated tea leaves but the most important source is teabags when steeped in boiling water. Here, more than 109 MNPs have been reported to be released per plastic teabag. However, significant quantities of MNPs are also released when plastic-cellulosic composite and biodegradable bags are steeped. Discrepancies among different studies partly reflect inter-brand and inter-material differences, but a more general cause is the adoption of different analytical protocols, including different size cutoffs used during isolation and constrained by identification. Some studies have also reported leaching of plastic additives and residues on steeping, although it is not clear whether these are released from the intact teabags or MNPs that are subsequently mobilised. As teabags generate concentrations of MNPs greater than other beverages or foodstuffs, potential impacts on human health and the environment are a concern and require further study.

Onboard measurement of polyethylene microplastics on a research vessel using Raman micro-spectroscopy: A preliminary study for testing feasibility. MARINE POLLUTION BULLETIN 2025; 212:117588. [PMID: 39864352 DOI: 10.1016/j.marpolbul.2025.117588] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/13/2024] [Revised: 01/15/2025] [Accepted: 01/17/2025] [Indexed: 01/28/2025]
Abstract
Microplastic pollution in marine environments poses significant environmental risks due to its widespread presence. Traditional micro-imaging measurement of microplastics often rely on post-cruise laboratory analyses. In this study, we explored the feasibility of onboard microplastic measurement using Raman spectroscopy, with a focus on polyethylene (PE). A measurement system was developed, and two concentration estimation approaches were proposed. To evaluate recovery and validate the methodology, artificial microplastic samples were prepared, yielding a recovery rate of 94.8 % ± 10.4 %. Environmental samples were then analyzed using the developed system, with results validated against conventional Fourier-transform infrared (FTIR) spectroscopy. The estimated PE concentration was 583 pieces/m3 (95% confidence interval: [2, 1542] pieces/m3) using the direct approach and 1453 pieces/m3 (95% credible interval: [291, 92,837] pieces/m3) using the Bayesian approach. Both estimates were consistent with the 333 pieces/m3 obtained through validation with FTIR, indicating adequate accuracy. However, the wide confidence intervals highlight the need for improved precision. While challenges remain, this study provides a comprehensive experimental procedure and introduces a robust data analysis framework, which could offer a foundational methodology for future onboard microplastic measurement research.

A comprehensive analysis and risk evaluation of microplastics contamination in Australian commercial plant growth substrates: Unveiling the invisible threat. JOURNAL OF HAZARDOUS MATERIALS 2024; 480:136310. [PMID: 39486335 DOI: 10.1016/j.jhazmat.2024.136310] [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: 08/28/2024] [Revised: 10/21/2024] [Accepted: 10/24/2024] [Indexed: 11/04/2024]
Abstract
In Australia, quality standards for composts and potting mixes are defined by AS4454-2012 and AS3743-2012. These standards outline key parameters, including physicochemical properties, nutrient content, and plant toxicity. However, they do not address emerging pollutants like microplastics (< 1 mm). This study investigates the prevalence and characteristics of MPs in commercial plant growth substrates (PGS), including nineteen potting mixes and five composts, revealing a significant occurrence of MPs, with concentrations ranging from 233 to 7367 particles Kg-1 and an average of 1869 ± 109 particles Kg-1. MPs categorized by shape, size, and color, with fragments (491 ± 34 particles Kg-1), white colour (3700 ± 917 particles Kg-1), and size 500 µm being predominant. The polymer composition was diverse, with polyethylene being the most prevalent, followed by polypropylene and others. Polyterpene, Polyalkene, Pentaerythritol, and Propylene glycol were identified in PGS for the first time. The structural equation model showed that physicochemical properties like pH, EC, TOC, and heavy metals influence MPs abundance and characteristics. The Polymer Risk Index and Pollution Load Index indicated varying risk levels among the samples. These findings highlight the need to address MPs contamination in PGS to ensure ecosystem safety and human health.

Abstract
Urban rivers are closely related to human life, and due to the widespread use of plastic products, rivers have become important carriers of pollutants such as microplastics (MP), phthalate esters (PAEs), and bisphenol A (BPA). However, our understanding of the distribution characteristics and relationships of MP, PAEs, and BPA in rivers is limited. In this study, MP, six PAEs and BPA were detected in the water and sediments of the Beiyun River basin. Polyvinyl chloride (PVC) was the most abundant type of microplastic, while di(2-ethylhexyl) phthalate (DEHP) and dibutyl phthalate (DBP) were the most abundant PAEs. MP, PAEs, and BPA in both water and sediment showed positive correlations, with stronger correlations and higher pollution levels in sediment than in water. The tendency for PAE congeners to partition into sediments increased with a higher octanol-water partition coefficient (Kow). There was a significant positive correlation between the distribution tendency of ∑6PAEs and TOC in sediments with a pearson correlation coefficient of 0.717. Rivers with more frequent human activities and higher levels of urbanization in the vicinity had a higher abundance of various pollutants and a greater diversity of MP types.

JOURNAL OF HAZARDOUS MATERIALS 2024; 480:136194.

Abstract
The pervasive utilization of plastic tools in aquaculture introduces significant volumes of microplastic fibers, presenting a consequential risk through the leaching of additives such as phthalates. This study scrutinizes the leaching dynamics of six prevalent phthalate esters (PAEs) from thirteen plastic aquaculture tools comprising polyethylene terephthalate (PET), polypropylene (PP), and polyethylene (PE), with ΣPAEs ranging from 0.24 to 4.26 mg g-1. Di(2-ethylhexyl) phthalate (DEHP) and dibutyl phthalate (DBP) emerged as predominant, marking significant environmental concern. Over a 30-day period, leaching quantities of Σ6PAEs from PET, PP, and PE fibers reached 36.65 μg g-1, 21.87 μg g-1 and 19.11 μg g-1, respectively, influenced by factors such as time, temperature, turbulence, and salinity. Notably, turbulence exerted the most pronounced effect, followed by temperature, with negligible influence from salinity. The kinetic models aligning with interface diffusion control was developed, predicting PAEs' leaching behavior with activation energies (Ea) indicative of the process's thermodynamic nature. The application of this model to real-world aquaculture waters forecasted significant risks, corroborating with empirical data and underscoring the pressing need for regulatory and mitigation strategies against PAEs contamination from aquaculture practices.

Teabag-derived micro/nanoplastics (true-to-life MNPLs) as a surrogate for real-life exposure scenarios. CHEMOSPHERE 2024; 368:143736.

Abstract
The potential health implications of environmental micro/nanoplastics (MNPLs) are increasingly concerning. Beyond environmental exposure, other sources such as food packaging, including herbal/teabags, may also be significant. This study investigates the release of MNPLs from three commercially available teabags. By simulating tea preparation, MNPL samples were extracted and characterized using a range of analytical techniques: scanning electron microscopy (SEM), transmission electron microscopy (TEM), attenuated total reflectance/Fourier transform infrared spectroscopy (ATR-FTIR), dynamic light scattering (DLS), laser Doppler velocimetry (LDV), and nanoparticle tracking analysis (NTA). The results confirmed that the teabags were made of nylon-6 (NY6), polypropylene (PP), and cellulose (CL) and that microfibers and nano-range particles (NPLs) were present in the leachates. NTA data revealed that the number of released NPLs was 1.20 × 109/mL (PP; 136.7 nm), 1.35 × 108/mL (CL; 244 nm), and 8.18 × 106/mL (NY6; 138.4). The leachate particles were then stained with iDye Poly-Pink and used to expose three human intestine-derived cell types (Caco-2, HT29, and HT29-MTX) to assess their biointeractions and the role of the mucosubstances in vitro. The results demonstrated that after 24 h of exposure to 100 μg/mL NPLs, there was significant uptake of PP-NPLs in HT29-MTX cells, as a model of cells segregating high amount of mucus. A similar uptake was observed for CL-NPLs in HT29 and HT29-MTX cells, while NY6-NPLs were internalized preferentially in Caco-2 cells. These findings underscore the importance of identifying new environmentally relevant MNPL exposure sources, for developing realistic MNPLs samples, and further investigating their potential human health effects.

Abstract
Tea, sold as tea bags or loose tea, is a popular drink worldwide. We quantified microplastics in loose tea during various stages of production, from planting to processing and brewing. The quantity of microplastics in tea ranged from (70-3472 pcs/kg), with the highest abundance detected during processing, mainly in the rolling stage (2266 ± 1206 pcs/kg tea). Scanning electron microcopy revealed scratches and pits on the surface of microplastics fibers from tea plantation soil and processed tea, and their degradation was characterized by cracks and fractures. Exposure risks, based on an estimated dietary intake of 0.0538-0.0967 and 0.0101-0.0181 pcs /kg body weight /day for children and adults, respectively, are considered very low. This study not only evaluates the extent of research on microplastics pollution in tea, but also assess the risk of people's exposure to microplastics through drinking tea.

Abstract
The occurrence and health risks of fluorescent whitening agents (FWAs) in bottled water were reported for the first time. FWA184 and FWA393 were the most frequently detected FWAs, with mean concentrations of 3.99-17.00 ng L-1. Phthalates (PAEs) such as dibutyl phthalate (DBP), di-iso-butyl phthalate (DiBP), and diethylhexyl phthalate (DEHP) were prevalent in bottled water, with mean levels of 40.89-716.66 ng L-1, and their concentrations in bottled water were much higher than those of FWAs. FWAs and PAEs in bottles and caps were extracted using organic solvent, and the correlation analysis showed that FWA393 and DEHP most likely originated from bottles, while bottle caps were the main sources of DBP and DiBP. The calculated risk quotients (RQs) of target substances and all age groups were considerably lower than the threshold of 0.1, indicating that consuming bottled water containing these plastic additives was unlikely to pose health risks for people of all ages. However, RQ values for underage people were several times higher than those for adults and hence cannot be neglected; therefore, special attention should be paid to understand the potential risks posed by the exposure to these plastic additives during early life stages, especially the infant stage.

Abstract
Because of the significant environmental and health hazards imposed by di(2-ethylhexyl) phthalate (DEHP), a common plasticizer, developing safe and green techniques to degrade DEHP plasticizer is of huge scientific significance. It has been observed that environmental contamination of DEHP may also induce serious food safety problems because crops raised in plasticizers contaminated soils would transfer the plasticizer into foods, such as Baijiu. Additionally, when plastic packaging or vessels are used during Baijiu fermentation and processing, plasticizer compounds frequently migrate and contaminate the product. In this study, hairpin-like structured peptides with catalytically active sites containing serine, histidine and aspartic acid were found to degrade DEHP. Furthermore, after incorporating caffeic acid molecules at the N-terminus, the peptides could be attached onto foam titanium (Ti) surfaces via enediol-metal interactions to create an enzyme-mimicking flow reactor for the degradation of DEHP in Baijiu. The structure and catalytic activity of peptides, their interaction with DEHP substrate and the hydrolysis mechanism of DEHP were discussed in this work. The stability and reusability of the peptide-modified foam Ti flow reactor were also investigated. This approach provides an effective technique for the degradation of plasticizer compounds.

JOURNAL OF HAZARDOUS MATERIALS 2024; 470:134169. [PMID: 38565022 DOI: 10.1016/j.jhazmat.2024.134169] [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: 01/05/2024] [Revised: 02/05/2024] [Accepted: 03/28/2024] [Indexed: 04/04/2024]
Abstract
Microplastic (MP) pollution poses a significant threat to marine ecosystem and seafood safety. However, comprehensive and comparable assessments of MP profiles and their ecological and health in Chinese farming oysters are lacking. This study utilized laser infrared imaging spectrometer (LDIR) to quantify MPs in oysters and its farming seawater at 18 sites along Chinese coastlines. Results revealed a total of 3492 MPs in farmed oysters and seawater, representing 34 MP types, with 20-100 µm MP fragments being the dominant. Polyurethane (PU) emerged as the predominant MP type in oysters, while polysulfones were more commonly detected in seawater. Notably, oysters from the Bohai Sea exhibited a higher abundance of MPs (13.62 ± 2.02 items/g) and estimated daily microplastic intake (EDI, 2.14 ± 0.26 items/g/kg·bw/day), indicating a greater potential health risk in the area. Meanwhile, seawater from the Yellow Sea displayed a higher level (193.0 ± 110.7 items/L), indicating a greater ecological risk in this region. Given the pervasiveness and abundance of PU and its high correlation with other MP types, we proposed PU as a promising indicator for monitoring and assessing the risk MP pollution in mariculture in China. These findings provide valuable insights into the extent and characteristics of MP pollution in farmed oysters and seawater in China.

Abstract
A significant and pressing issue revolves around the potential human exposure to endocrine disrupting chemicals (EDCs), which pose a substantial risk primarily through contaminated beverages. However, a comprehensive review for comparison of the migration rates of EDCs into these matrixes is currently lacking. This study reviews the beverages contamination with EDCs, including phthalates (PAEs), bisphenol A (BPA), hormone-like compounds, elements, and other organic EDCs. Also, the EDCs migration into milk and other dairy products, coffee, tea, and cold beverages related to their release from contact materials, preparation components, and storage conditions are briefly summarized. The data illustrates that besides the contamination of raw materials, the presence of EDCs associated with the type of food contact materials (FCMs)and their migration rate is increased with acidity, temperature, and storage time. The highest concentration of PAEs was detected from plastic and synthetic polymer films, while BPA strongly leaches from epoxy resins and canned metal. Furthermore, the presence of elements with endocrine disrupting characteristics was confirmed in cold beverages, soft drinks, hot drink and milk. Moreover, hormone-like compounds have been found to be released from coffee preparation components. Despite the few data about the migration rate of other EDCs including UV-stabilizers, surfactants, and antibacterial compounds into beverages, their presence was reported into milk, coffee, and different beverages, especially in packed samples. Studies on the EDCs leaching have primarily focused on PAEs and BPA, while other compounds require further investigation. Regardless, the possible risk that EDCs pose to humans through beverage consumption cannot be overlooked.

Critical review on airborne microplastics: An indoor air contaminant of emerging concern. ENVIRONMENTAL RESEARCH 2024; 245:118055. [PMID: 38154562 DOI: 10.1016/j.envres.2023.118055] [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: 10/10/2023] [Revised: 12/15/2023] [Accepted: 12/25/2023] [Indexed: 12/30/2023]
Abstract
Airborne Microplastics (MPs), an emerging environmental issue, have gained recent attention due to their newfound presence in indoor environments. Utilizing the Web of Science database for literature collection, the paper presents a comprehensive review of airborne MPs including emission sources, assessment methods, exposure risks, and mitigation strategies. This review delves into the diverse sources and mechanisms influencing indoor airborne MP pollution, underscoring the complex interplay between human activities, ventilation systems, and the characteristics of indoor environments. Major sources include the abrasion of synthetic textiles and the deterioration of flooring materials, with factors like carpeting, airflow, and ventilation significantly impacting MP levels. Human activities, such as increased movement in indoor spaces and the intensive use of plastic-based personal protective equipment (PPE) post-pandemic, notably elevate indoor MP concentrations. The potential health impacts of airborne MPs are increasingly concerning, with evidence suggesting their role in respiratory, immune, and nervous system diseases. Despite this, there is a scarcity of information on MPs in diverse indoor environments and the inhalation risks associated with the frequent use of PPE. This review also stresses the importance of developing effective strategies to reduce MP emissions, such as employing HEPA-filtered vacuums, minimizing the use of synthetic textiles, and enhancing indoor ventilation. Several future research directions were proposed, including detailed temporal analyses of indoor MP levels, interactions of MP with other atmospheric pollutants, the transport dynamics of inhalable MPs (≤10 μm), and comprehensive human exposure risk assessments.

MARINE POLLUTION BULLETIN 2024; 199:116031.

Abstract
This paper presents the phthalate esters (PAEs), nonylphenol (NPs), and microplastics (MPs) in river sediments. Results showed that sediments near residential areas were mainly composed of fine particles, potentially influencing the adsorption of PAEs and NPs in the area. The concentrations of Σ10 PAEs in the sediments ranged between 2448 and 63,457 μg/kg dw, dominated by DEHP and DnOP. Microplastics were detected in all samples, with higher abundances found in sediments near residential areas dominated by polypropylene. Toxicological risk assessment indicated potential risks to sensitive aquatic organisms exposed to the sediments. Correlations between MPs, PAEs, and NPs suggest that MPs may serve as possible sources of PAEs in the sediments. Principal component analysis explained 95.4 % of the pollutant variability in the sediments. Overall, this study emphasizes the significance of monitoring and understanding the presence and interactions of PAEs and MPs in river sediments to assess their potential impacts on aquatic ecosystems.
