Microplastics (MPs) and nanoplastics (NPs) pollution has emerged as a significant widespread environmental issue. Humans are inevitably exposed to MPs NPs via ingestion, inhalation, dermal contacts from various sources. However, mechanistic knowledge of their distribution, interaction, potency in the body is still lacking. To address this gap, we have undertaken task elucidating toxicokinetic (TK) behaviors NPs, aiming provide information for constructing conceptual physiologically based (PBTK) model support silico modeling approaches. Our effort involved thorough examination existing literature data collation on presence human vitro/ex vivo/in vivo biodistribution across cells tissues. By comprehending absorption, metabolism, excretion mechanisms relation physicochemical attributes, established foundational understanding link between external exposure internal tissue dosimetry. We observed that particle size surface chemistry been thoroughly explored previous experimental studies. certain such polymer type, shape, biofilm/biocorona, warrant attention further examination. discussed fundamental disparities TK properties MPs/NPs those engineered nanoparticles. proposed preliminary PBTK framework with several possible approaches challenges investigation. Overall, article provides comprehensive compilation MPs/NPs, critical overview processes mechanisms, proposes potential approaches, particularly regarding applicability system, outlines future perspectives developing models integration into health risk assessment NPs.

Plastics in biota: technological readiness level of current methodologies

Microplastics and Nanoplastics, Год журнала: 2024, Номер 4(1)

Опубликована: Март 15, 2024

Abstract Plastics are persistent in the environment and may be ingested by organisms where they cause physical harm or release plastic additives. Monitoring is a crucial mechanism to assess risk of plastics marine terrestrial ecosystem. Unfortunately, due unharmonised procedures, it remains difficult compare results different studies. This publication, as part Horizon project EUROqCHARM, aims identify properties available analytical processes methods for determination biota. Based on systematic review, reproducible pipelines were examined technological readiness levels assessed so that these eventually (if not already) incorporated into (harmonised) monitoring programs biota identified indicators pollution.

Mechanism Involved in Polyvinyl Chloride Nanoplastics Induced Anaerobic Granular Sludge Disintegration: Microbial Interaction Energy, EPS Molecular Structure, and Metabolism Functions

Environmental Science & Technology, Год журнала: 2024, Номер 58(26), С. 11542 - 11553

Опубликована: Июнь 13, 2024

Nanoplastics (NPs) are emerging pollutants and have been reported to cause the disintegration of anaerobic granular sludge (AnGS). However, mechanism involved in AnGS was not clear. In this study, polyvinyl chloride nanoplastics (PVC-NPs) were chosen as target NPs their long-term impact on structure investigated. Results showed that increasing PVC-NPs concentration resulted inhibition acetoclastic methanogens, syntrophic propionate, butyrate degradation, well disintegration. At presence 50 μg·L

Plastic residues have emerged as a significant challenge in the environmental sector. Microplastics, which are plastic fragments smaller than 5 mm, ability to disperse through atmosphere, oceans, and land, posing serious threat human health by accumulating food chain. However, their minuscule size makes it difficult effectively remove them from environment using current technologies. This work provides comprehensive overview of recent advancements microplastic detection removal For methods, we discuss commonly used techniques such microscopic analysis, thermal mass spectrometry, spectroscopic energy spectrometry. We also emphasize importance integrating various analytical data-processing achieve efficient nondestructive microplastics. In terms strategies, explored innovative methods technologies for extracting microplastics environment.
