As plastic products are widely used in all walks of life, waste is also accumulating the environment. Today, microplastic pollution soil environment has become an environmental issue global concern. Compared with water environment, research on microplastics relatively lacking. Based above situation, this paper systematically reviews distribution characteristics, influencing factors, and ecological risks The abundance, impacts soils globally recent years reviewed detail. Our review suggests that most scholars only focus surface soil, determination accumulation as a whole still lacking, there no uniform standard for sampling techniques, extraction methods, analytical procedures, even expression units microplastics. affected by human natural physical chemical properties plastics themselves. We focused analysis arising from interacting metals organic pollutants, found large gaps exist interaction between pollutants mechanism compound pollution. impact animals, microorganisms, plants explained.

LDPE and biodegradable PLA-PBAT plastics differentially affect plant-soil nitrogen partitioning and dynamics in a Hordeum vulgare mesocosm

Journal of Hazardous Materials, Journal Year: 2023, Volume and Issue: 447, P. 130825 - 130825

Micro and macroplastics are emerging contaminants in agricultural settings, yet their impact on nitrogen (N) cycling partitioning plant-soil-microbial systems is poorly understood. In this mesocosm-scale study, spring barley (Hordeum vulgare L.) was exposed to macro or microplastic produced from low density polyethylene (LDPE) biodegradable plastic at concentrations equivalent 1, 10 20 years of mulch film use. Partitioning 15N-labelled fertiliser into plant biomass, soil leachate yielded a partial mass balance. Soil N probed via compound-specific 15N-stable isotope analyses microbial protein. Concentration-dependent decreases 15N uptake occurred with increased leached for LDPE microplastic. Assimilation protein higher plastics, which we associate early-stage degradation. inorganic pools affected by size, lower assimilation the pool. While microplastics altered cycling, limited impacts health indicated threshold negative effects not reached agriculturally relevant concentrations. This study highlights difference between conventional emphasises that interplay micro must be considered future studies.

Interactions of Microplastics with Pesticides in Soils and Their Ecotoxicological Implications

Agronomy, Journal Year: 2023, Volume and Issue: 13(3), P. 701 - 701

In the middle of 20th century, production plastics exploded worldwide because their low cost and versatility applications. However, since plastic debris is highly resistant to environmental degradation, a growing presence in all ecosystems has been confirmed. Among them, particles < 5 mm, also known as microplastics (MPs), are special concern they dispersed aerial, terrestrial aquatic environments, being soil main sink these contaminants. Due large specific surface area hydrophobicity, MPs considered good adsorbents for other organic pollutants present ecosystems, such pharmaceuticals, personal-care products or pesticides with which can interact thus modify fate. this review article, we examine recent literature (from 2017 2022) get better understanding fate (adsorption, mobility and/or degradation) when simultaneously ecological risks on living organisms interactions between soil. More studies needed fully understand toxicological impact copresence MPs.

The forgotten impacts of plastic contamination on terrestrial micro- and mesofauna: A call for research

Environmental Research, Journal Year: 2023, Volume and Issue: 231, P. 116227 - 116227

Published: May 25, 2023

Microplastics (MP) and nanoplastics (NP) contamination of the terrestrial environment is a growing concern worldwide thought to impact soil biota, particularly micro mesofauna community, by various processes that may contribute global change in systems. Soils act as long-term sink for MP, accumulating these contaminants increasing their adverse impacts on ecosystems. Consequently, whole ecosystem impacted microplastic pollution, which also threatens human health potential transfer food web. In general, ingestion MP different concentrations can adversely affect development reproduction, impacting moves horizontally vertically because movement organisms disturbance caused plants. However, effects micro-and are largely overlooked. Here, we give most recent information forgotten microfauna communities (protists, tardigrades, rotifers, nematodes, collembola mites). More than 50 studies focused between 1990 2022 have been reviewed. plastic pollution does not directly survival organisms, except under co-contaminated plastics increase (e.g. tire-tread particles springtails). Besides, they at oxidative stress reduced reproduction potworms, springtails or It was observed could passive transporters, shown mites. Finally, this review discusses how micro- play key role facilitating (bio-)degradation NP through systems and, therefore, depths. research should be mixtures, community level experiments.
