Microplastics in the soil environment: A critical review

Environmental Technology & Innovation, Journal Year: 2022, Volume and Issue: 27, P. 102408 - 102408

Published: Feb. 12, 2022

Environmental pollution of microplastics (MPs) is known to be anthropogenically mediated menace biosphere and becoming a debatable concern globally. Large quantities plastic fragments are left behind after crop cultivation. The leftover debris, gradually degrade into minute with diameter less than 5 mm, as MPs. MPs responsible for many changes in the soil physicochemical characteristics, including porosity, enzymatic activities, microbial plant growth, yield. Because their ubiquitous nature, high specific surface area strong hydrophobicity, play an important role transportation toxic chemicals such plasticisers, polycyclic aromatic hydrocarbons (PAHs), antibiotics, potentially elements (PTEs). may transported deep can pollute underground water. This review paper investigates deleterious effects on environment, microbes, flora, fauna production, highlights general concept contamination well its possible environmental consequences. also converses some key areas future research stakeholders concerned policymaking

Toxicity of micro/nanoplastics in the environment: Roles of plastisphere and eco-corona

Soil & Environmental Health, Journal Year: 2023, Volume and Issue: 1(1), P. 100002 - 100002

Published: Feb. 28, 2023

Micro/nanoplastics (MPs/NPs) are a growing threat to environmental health as these particles dispersed remote locations. However, the migration process of NPs differs from MPs due their differences in sizes and physicochemical properties, thereby inducing different behaviours fates. While provide surfaces host microorganisms form plastisphere, smaller than microorganisms, which often encapsulated by protein or organic matter unique eco-corona. Both plastisphere eco-corona alter physiochemical property MPs/NPs, changing toxicity. To fully understand toxicity MPs/NPs after forming eco-corona, this review aims evaluate roles toxicities environment. Specifically, discusses formation on NPs, summarizes biochemical mechanisms assesses potential threats humans. Finally, perspectives provided better manage plastic pollution protect environment human health.

Plastic mulching, and occurrence, incorporation, degradation, and impacts of polyethylene microplastics in agroecosystems

Ecotoxicology and Environmental Safety, Journal Year: 2023, Volume and Issue: 263, P. 115274 - 115274

Polyethylene microplastics have been detected in farmland soil, irrigation water, and soil organisms agroecosystems, while plastic mulching is suggested as a crucial source of microplastic pollution the agroecosystem. Plastic mulch can be broken down from debris to through environmental aging degradation process farmlands, colonization polyethylene-degrading microorganisms on polyethylene eventually enzymatically depolymerize molecular chains with CO2 release tricarboxylic acid cycle.

Microplastic pollution promotes soil respiration: A global‐scale meta‐analysis

Global Change Biology, Journal Year: 2024, Volume and Issue: 30(7)

Published: July 1, 2024

Abstract Microplastic (MP) pollution likely affects global soil carbon (C) dynamics, yet it remains uncertain how and to what extent MP influences respiration. Here, we report on a meta‐analysis determine the effects of microbiome CO 2 emission. We found that significantly increased contents organic C (SOC) (21%) dissolved (DOC) (12%), activity fluorescein diacetate hydrolase (FDAse) (10%), microbial biomass (17%), but led decrease in diversity (3%). In particular, increases components further promote emission (25%) from soil, with much higher effect MPs these emissions than biomass. The could be attributed opposite vs. diversity, as accumulation recruited some functionally important bacteria provided additional substrates for specific heterotrophic microorganisms, while inhibiting growth autotrophic taxa (e.g., Chloroflexi , Cyanobacteria ). This study reveals can increase by causing shifts microbiome. These results underscore potential importance plastic terrestrial fluxes, thus climate feedbacks.

Response of soybean and maize roots and soil enzyme activities to biodegradable microplastics contaminated soil

Ecotoxicology and Environmental Safety, Journal Year: 2023, Volume and Issue: 262, P. 115129 - 115129

Published: June 12, 2023

Although biodegradable plastic film is a promising alternative product for reducing polyethylene pollution in agricultural soils, the effects of its residues on plant growth and soil properties remain unclear. In this study, we conducted an experiment to investigate root enzyme activities Poly (butylene adipate-co-terephthalate) microplastics (PBAT-MPs) contaminated (0 % (CK), 0.1 %, 0.2 0.5 1 dry weight) with soybean (Glycine max (Linn.) Merr.) maize (Zea mays L.). The results show that PBAT-MP accumulation negatively affects growth, alter activities, which may then constrain C/N cycling potential yields. For soybean, total length, surface area biomass decreased by 34 %- 58 54 25 40 at harvesting stage compared CK, respectively. negative PBAT-MPs roots were greater than roots. 37 71 33 24 64 tasseling stage, respectively (p < 0.05).
