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

Response of common bean (Phaseolus vulgaris L.) growth to soil contaminated with microplastics

The Science of The Total Environment, Journal Year: 2020, Volume and Issue: 755, P. 142516 - 142516

Published: Sept. 24, 2020

Although concerns surrounding microplastics (MPs) in terrestrial ecosystems have been growing recent years, little is known about the responses of plant growth to MPs pollution. Here, we conducted a pot experiment net house under natural condition by adding two types MPs, low-density polyethylene (LDPE-MPs) and polylactic acid (PLA) mixed with poly-butylene-adipate-co-terephthalate (PBAT, Bio-MPs), sandy soil at 5 doses (0.5%, 1.0%, 1.5%, 2.0%, 2.5% ω/ω dry weight). The effects LDPE-MPs Bio-MPs on common bean (Phaseolus vulgaris L) were tested. Compared control (no addition), showed no significant shoot, root fruit biomass while ≥1.0% higher specific nodules (n·g−1 biomass) only length (cm·g−1 biomass). 1.0% caused leaf area 0.5% lower relative chlorophyll content. For treatment, compared control, ≥1.5% shoot biomass. ≥2.0% All treatments as control. results current research show that both induced growth, exerted stronger effects. Further studies their ecological impacts soil-plant systems are urgently needed.

Uptake and Accumulation of Nano/Microplastics in Plants: A Critical Review

Nanomaterials, Journal Year: 2021, Volume and Issue: 11(11), P. 2935 - 2935

Published: Nov. 2, 2021

The ubiquitous presence of microplastics (MPs) and nanoplastics (NPs) in the environment is an undeniable serious concern due to their higher persistence extensive use agricultural production. This review highlights sources fate MPs NPs soil uptake, translocation, physiological effects plant system. We provide current snapshot latest reported studies with majority literature spanning last five years. draw attention potential risk modern agriculture on growth development. also highlight uptake transport pathways roots leaves via different exposure methods plants. Conclusively, practices, climate changes (wet weather heavy rainfall), organisms play a major role transporting soil. are more prone enter cell walls as compared MPs. Furthermore, transpiration pull dominant factor translocation plastic particles. have negligible negative biochemical indicators. Overall, there dire need establish long-term for better understanding associated risks mechanisms realistic scenarios safe functions.
