Macro- and micro- plastics in soil-plant system: Effects of plastic mulch film residues on wheat (Triticum aestivum) growth

The Science of The Total Environment, Journal Year: 2018, Volume and Issue: 645, P. 1048 - 1056

Plastic residues have become a serious environmental problem in the regions with intensive use of plastic mulching. Even though mulch is widely used, effects macro- and micro- on soil-plant system agroecosystem are largely unknown. In this study, low density polyethylene one type starch-based biodegradable film were selected used as examples sized residues.

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. This review aims gaps knowledge, shed light propose future studies microplastic pollution resultant ecotoxicity. Furthermore, this limiting establishing management remediation measures mitigate posed pollution.

Plastic rain in protected areas of the United States

Eleven billion metric tons of plastic are projected to accumulate in the environment by 2025. Because plastics persistent, they fragment into pieces that susceptible wind entrainment. Using high-resolution spatial and temporal data, we tested whether deposited wet versus dry conditions have distinct atmospheric life histories. Further, report on rates sources deposition remote U.S. conservation areas. We show urban centers resuspension from soils or water principal for wet-deposited plastics. By contrast, under were smaller size, related indices suggest longer-range global transport. Deposition averaged 132 per square meter day, which amounts >1000 western protected lands annually.
