The harmful effects of microplastics (MPs) pollution in the soil ecosystem have drawn global attention recent years. This paper critically reviews MPs on microbial diversity and functions relation to nutrients carbon cycling. Reports suggested that both plastisphere (MP-microbe consortium) MP-contaminated soils had distinct lower than non-contaminated soils. Alteration physicochemical properties interactions within facilitated enrichment plastic-degrading microorganisms, including those involved (C) nutrient conferred a significant increase relative abundance nitrogen (N)-fixing phosphorus (P)-solubilizing bacteria, while decreased nitrifiers ammonia oxidisers. Depending types, increased bioavailable N P contents nitrous oxide emission some instances. Furthermore, regulated functional activities owing combined toxicity organic inorganic contaminants derived from frequently encountered environment. However, thorough understanding among other still needs develop. Since currently available reports are mostly based short-term laboratory experiments, field investigations needed assess long-term impact (at environmentally relevant concentration) microorganisms their under different types agro-climatic conditions.

Environmental Science & Technology, Journal Year: 2024, Volume and Issue: 58(13), P. 5821 - 5831

Published: Feb. 28, 2024

Microplastics (MPs) contamination presents a significant global environmental challenge, with its potential to influence soil carbon (C) dynamics being crucial aspect for understanding C changes and cycling. This meta-analysis synthesizes data from 110 peer-reviewed publications elucidate the directional, magnitude, driving effects of MPs exposure on globally. We evaluated impacts characteristics (including type, biodegradability, size, concentration), properties (initial pH organic [SOC]), experimental conditions (such as duration plant presence) various components. Key findings included promotion SOC, dissolved C, microbial biomass root following addition soils, while net photosynthetic rate was reduced. No were observed respiration shoot biomass. The study highlights that concentration, along other attributes, critically influences responses. Our results demonstrate both nature environment interact shape cycling, providing comprehensive insights guiding strategies mitigating impact MPs.

Plastics have revolutionised human industries, thanks to their versatility and durability. However, extensive use, coupled with inadequate waste disposal, has resulted in plastic becoming ubiquitous every environmental compartment, posing potential risks the economy, health environment. Additionally, under natural conditions, breaks down into microplastics (MPs<5 mm). The increasing quantity of MPs exerts a significant burden on soil environment, particularly agroecosystems, presenting new stressor for soil-dwelling organisms. In this review, we delve effects MP pollution ecosystems, specific attention (a) transport soils, (b) changes (c) interaction physical, chemical biological components soil. We aim shed light alterations distribution, activity, physiology growth flora, fauna microorganisms response MPs, offering an ecotoxicological perspective risk assessment plastics. are strongly influenced by intrinsic traits, including polymer type, shape, size abundance. By exploring multifaceted interactions between provide critical insights consequences contamination. Despite growing body research, there remain substantial knowledge gaps regarding long-term impact Our work underscores importance continued research efforts adoption standardised approaches address ensure sustainable future our planet.
