Evidence of microplastic accumulation in agricultural soils from sewage sludge disposal

The Science of The Total Environment, Journal Year: 2019, Volume and Issue: 671, P. 411 - 420

Published: March 24, 2019

Microplastics are emerging as a steadily increasing environmental threat. Wastewater treatment plants efficiently remove microplastics from sewage, trapping the particles in sludge and preventing their entrance into aquatic environments. Treatment essentially taking out of waste water concentrating them sludge, however. It has become common practice to use this on agricultural soils fertilizer. The aim current research was evaluate microplastic contamination by practice, assessing implications successive applications looking at total count soil samples. Thirty-one fields with different application records similar edaphoclimatic conditions were evaluated. Field covered ten year period. For all fields, historical disposal events used same amount (40 ton ha-1 dry weight). Extraction done flotation then counted classified help microscope.

The effects of microplastics (MP) on aquatic organisms are currently the subject intense research. Here, we provide a critical perspective published studies MP ingestion by biota. We summarize available research presence, behaviour and monitored in field laboratory ecotoxicological consequences ingestion. consider polymer type, shape, size as well group studied type effect reported. Specifically, evaluate whether or not representative types MPs found environment they have reported relevant groups organisms. Analysis data revealed that 1) despite their widespread detection field-based studies, polypropylene, polyester polyamide particles were under-represented studies; 2) fibres fragments (800–1600 μm) most common form animals collected from field; 3) to date, been conducted fish; knowledge is needed about other organisms, especially invertebrates. Furthermore, there significant mismatches between commonly those used experiments. Finally, an overarching need understand mechanism action environmentally concentrations organism health.

Atmospheric microplastics: A review on current status and perspectives

Earth-Science Reviews, Journal Year: 2020, Volume and Issue: 203, P. 103118 - 103118

Published: Feb. 10, 2020

Microplastics have recently been detected in the atmosphere of urban, suburban, and even remote areas far away from source regions microplastics, suggesting potential long-distance atmospheric transport for microplastics. There still exist questions regarding occurrence, fate, transport, effect These arise due to limited physical analysis understanding microplastic pollution conjunction with a lack standardized sampling identification methods. This paper reviews current status knowledge on methods sample collection, detection. We review compare used previous studies provide recommendations measurement. Furthermore, we summarize findings related characteristics, including abundance, size, shapes, colours, polymer types. occur urban areas, an abundance/deposition spanning 1–3 orders magnitude across different sites. Fibres fragments are most frequently reported shapes types plastic which generally aligns world demand. conclude that microplastics require further research greater identify its global distributions exposure human health through field implementation analytical protocols.

Source, migration and toxicology of microplastics in soil

Environment International, Journal Year: 2020, Volume and Issue: 137, P. 105263 - 105263

Published: Feb. 19, 2020

Microplastics are emerging contaminants and their presence in water soil ecosystems has recently drawn considerable attention because they pose a great threat to entire ecosystems. Recent researches have focused on the detection, occurrence, characterization, toxicology of microplastics marine freshwater ecosystems; however, our understanding ecological effects is still limited compared with that aquatic Here, we compiled literature, studying sources, migration soil, negative impacts health function, trophic transfer food chains, corresponding adverse organisms order address potential human risks caused by soil.

Microplastics in wild fish from North East Atlantic Ocean and its potential for causing neurotoxic effects, lipid oxidative damage, and human health risks associated with ingestion exposure

Microplastics (MP) pollution has received increased attention over the last few years. However, while number of studies documentating ingestion microplastics by fish increased, fewer have addressed toxicological effects derived from these small items in wild conditions. Here, MP contamination and effect biomarkers were investigated three commercially important species North East Atlantic Ocean. From 150 analysed (50 per species), 49 % had MP. In 3 species, gastrointestinal tract, gills dorsal muscle found. Fish with significantly (p ≤ 0.05) higher lipid peroxidation levels brain, muscle, brain acetylcholinesterase activity than where no These results suggest oxidative damage neurotoxicity through induction relation to and/or MP-associated chemicals exposure. analysed, 32 a total mean (± SD) 0.054 ± 0.099 items/g.
