Plastic pollution is ubiquitous in terrestrial and aquatic ecosystems. waste exposed to the environment creates problems of significant concern for all life forms. production accumulation natural are occurring at an unprecedented rate due indiscriminate use, inadequate recycling, deposits landfills. In 2019, global plastic was 370 million tons, with only 9% it being recycled, 12% incinerated, remaining left or The leakage wastes into ecosystems rate. management a challenging problem researchers, policymakers, citizens, other stakeholders. Therefore, here, we summarize current understanding concerns plastics (microplastics nanoplastics) on overall goal this review provide background assessment adverse effects ecosystems; interlink sustainable development goals; address policy initiatives under transdisciplinary approaches through cycle assessment, circular economy, sustainability; identify knowledge gaps; recommendations. community involvement socio-economic inputs different countries presented discussed. ban policies public awareness likely major mitigation interventions. need circularity assess potential environmental impacts resources used throughout product’s span emphasized. Innovations needed reduce, reuse, recycle, recover find eco-friendly replacements plastics.

Microplastic residues in wetland ecosystems: Do they truly threaten the plant-microbe-soil system?

Environment International, Год журнала: 2021, Номер 156, С. 106708 - 106708

The ecological stress of microplastic contamination to ecosystem functioning and biota raises concerns worldwide, but the impacts microplastics on wetland ecosystems (e.g., plants, microbes, soil) have not been fully elucidated. In this study, we used a controlled pot experiment determine effects different types (PS, PVC, PP PE) growth performance soil chemical properties, enzyme systems microbial communities. Microplastics can change germination strategies seeds, there was also reduction in fresh weight plant height Bacopa sp. Chlorophyll b synthesis significantly reduced mixed treatments compared with controls. Microplastic addition caused higher concentrations reactive oxygen species which led increased lipid peroxidation activation antioxidant defence system. organic matter, potassium, total nitrogen phosphorus changed presence four forms microplastics, while pH substantially affected. had negative effect activity, for example, PS MP particles decreased sucrase activities after 40 days. results study showed that richness diversity bacterial. When exposed polystyrene algae surface. Thus, alters structure communities, resulting enrichment some special taxa involved cycling. These indicate both direct indirect plastic residues plant-microbe-soil system, has implications potential further functioning.

Identification and Quantification of Nanoplastics in Surface Water and Groundwater by Pyrolysis Gas Chromatography–Mass Spectrometry

Environmental Science & Technology, Год журнала: 2022, Номер 56(8), С. 4988 - 4997

Опубликована: Апрель 4, 2022

Nanoplastics (NPs) are currently considered an environmental pollutant of concern, but the actual extent NP pollution in water bodies remains unclear and there is not enough quantitative data to conduct proper risk assessments. In this study, a pretreatment method combining ultrafiltration (UF, 100 kDa) with hydrogen peroxide digestion subsequent detection pyrolysis gas chromatography–mass spectrometry (Py-GC/MS) was developed used identify quantify six selected NPs surface (SW) groundwater (GW), including poly(vinylchloride) (PVC), poly(methyl methacrylate) (PMMA), polypropylene (PP), polystyrene (PS), polyethylene (PE), poly(ethylene terephthalate) (PET). The results show that proposed could detect samples. Nearly all be detected at locations, while PVC, PMMA, PS, PET were frequently below limit groundwater. PP (32.9–69.9%) PE (21.3–44.3%) dominant components both groundwater, although significant differences levels attributed filtration efficiency riverbank, total mass concentrations 0.283–0.793 μg/L 0.021–0.203 (GW). Overall, study quantified complex aquatic environments for first time, filling gaps our knowledge about providing useful methodology important reference future research.
