A large number of individual studies and meta-analyses have shown that microplastics (MPs) affect soil ecosystems. However, the effects different concentrations types MPs on ecosystem are still unclear. Here, a comprehensive meta-analysis was performed to examine responses 19 variables, associated with properties, microbes, enzymes, fauna, MPs, based 114 peer-reviewed studies. The results showed addition significantly reduced organic carbon (SOC), total nitrogen (TN), NH4+-N, pH, diversity bacteria, increased dissolved (DOC), fungi enzyme activities, especially enzymes related biogeochemical cycle. We further discussed exerted negative including survival, growth, reproduction, concentration rather than type, biggest driving factor causing toxicity affecting animals. More importantly, were main DOC, TN, NO3--N, phosphorus (TP), available (AP), fungi, whereas factors reflected in SOC, activities. This study aimed evaluate response ecosystems largest for MPs.

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.

Polyethylene microplastics alter soil microbial community assembly and ecosystem multifunctionality

Environment International, Journal Year: 2023, Volume and Issue: 183, P. 108360 - 108360

Published: Nov. 30, 2023

Although pervasive microplastics (MPs) pollution in terrestrial ecosystems invites increasing concern, impact of MPs on soil microbial community assembly, and ecosystem functions multifunctionality received relatively little attention. Here, we manipulated a mesocosm experiment to investigate how polyethylene (PE MPs; 0, 1%, 5%, w/w) influence plant production, quality, diversity enzymology carbon (C), nitrogen (N) phosphorus (P) cycling, maize–soil continuum. Results showed that PE exerted negligible effect biomass (dry weight). The 5% caused declines the availability water, C P, whereas enhanced pH storage. activity C-cycling enzymes (α/β-1, 4-glucosidase, β-D-cellobiohydrolase) was promoted by 1% MPs, while β-1, 4-glucosidase inhibited MPs. reduced N-cycling (protease urease), increased P-cycling enzyme (alkaline phosphatase). shifted composition, number specialist species, stability networks resistance. altered with concentration decreasing dispersal limitation proportion (from 13.66 9.96%). Overall, improved concentration, α/β-1, urease, protease, ammonium-N content were most important predictors multifunctionality.

Presence of different microplastics promotes greenhouse gas emissions and alters the microbial community composition of farmland soil

The Science of The Total Environment, Journal Year: 2023, Volume and Issue: 879, P. 162967 - 162967

Published: March 21, 2023

Microplastics (MPs) are regarded as potential persistent organic pollutants owing to their small size and low degradability. However, the effect of MP pollution on greenhouse gas (GHG) emissions from farmland soil is yet unclear. Therefore, a series microcosm experiments were set up using polyvinyl chloride (PVC), polypropylene (PP), polyethylene (PE), polystyrene (PS), polyester (PET) at concentrations 0.25 %, 2 7 % (w/w). Each treatment had three replicates. This experiment was carried out verify soil. The results showed that addition MPs significantly promoted main GHGs, including nitrous oxide (N2O), carbon dioxide (CO2), methane (CH4). Especially, PE may cause most GHG which would contribute climate warming when its concentration increased. In addition, different doses types could affect microbial community structure. These findings this present study provide scientific practical reference for prevention control risk assessment global change caused by MPs.

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.
