Formation, behavior, properties and impact of micro- and nanoplastics on agricultural soil ecosystems (A Review)

NanoImpact, Journal Year: 2023, Volume and Issue: 31, P. 100474 - 100474

Published: July 1, 2023

Micro and nanoplastics (MPs NPs, respectively) in agricultural soil ecosystems represent a pervasive global environmental concern, posing risks to biota, hence health food security. This review provides comprehensive current summary of the literature on sources properties MNPs ecosystems, methodology for isolation characterization recovered from soil, MNP surrogate materials that mimic size soil-borne MNPs, transport through matrix. Furthermore, this elucidates impacts crops microorganisms fauna. A significant source MPs is plasticulture, involving use mulch films other plastic-based implements provide several agronomic benefits specialty crop production, while include irrigation water fertilizer. Long-term studies are needed address knowledge gaps formation, surface subsurface transport, including derived biodegradable films, which, although ultimately undergoing complete mineralization, will reside months. Because complexity variability difficulty recovering deeper understanding fundamental relationships between MPs, biota microbiota, ecotoxicological effects earthworms, soil-dwelling invertebrates, beneficial microorganisms, geochemical attributes. In addition, geometry, distribution, chemical properties, concentration contained soils required develop reference can be used across laboratories conducting laboratory studies.

Photoaging of biodegradable nanoplastics regulates their toxicity to aquatic insects (Chironomus kiinensis) by impairing gut and disrupting intestinal microbiota

Environment International, Journal Year: 2024, Volume and Issue: 185, P. 108483 - 108483

Biodegradable plastic, a widely used ecofriendly alternative to conventional easily form nanoplastics (NPs) upon environmental weathering. However, the effects and underlying mechanisms governing toxicity of photoaged biodegradable NPs aquatic insects are not understood. In this study, we investigated photoaging polylactic acid (PLA-NPs, typical plastic) that were placed under xenon arc lamp for 50 days 100 compared virgin PLA-NPs Chironomus kiinensis (a dominant insect). The results showed significantly decreased body weight, length emergence rate C. kiinensis. Additionally, induced more severe gut oxidative stress, histological damage, inflammatory responses than PLA-NPs. Furthermore, alpha diversity microbiota was lower in group relative abundance key bacteria related intestinal barrier defense, immunity, nutrient absorption reduced PLA, indirectly leading stronger damage growth reduction. A impact on its occurred because size from 255.5 nm (virgin PLA) 217.1 (PLA-50) 182.5 (PLA-100), surface oxidation enhancement potential, improved stability NPs, thereby exacerbating microbiota. This study provides insights into highlights importance considering nanoplastic aging risk assessments.

Exploring Environmental Behaviors and Health Impacts of Biodegradable Microplastics

Environmental Science & Technology, Journal Year: 2025, Volume and Issue: unknown

Published: March 21, 2025

Biodegradable plastics (BPs) are promoted as eco-friendly alternatives to conventional plastics. However, compared microplastics (MPs), they degrade rapidly into biodegradable (BMPs), which may lead a more significant accumulation of BMPs in the environment. This review systematically compares and MPs, summarizes current knowledge on their environmental behaviors impacts ecosystems human health, offers recommendations for future research. detected water, sediments, indoor dust, food, marine organisms, samples. Compared prone transformations, such photodegradation biodegradation, results shorter migration distance across different matrices. Like can adsorb pollutants transport them enhancing toxicity health risks through Trojan horse effect. Studies indicate that negatively impact terrestrial aquatic than MPs by disrupting nutrient cycling inhibiting plant animal growth. In vivo vitro research also shows BMP degradation products increase bioavailability, exacerbating neurotoxicity overall toxicity. findings BMPs' effects remain inconsistent. Further evaluation trade-offs between biodegradability is needed address these uncertainties.
