Although our understanding of the effects microplastics on dynamics soil organic matter (SOM) has considerably advanced in recent years, fundamental mechanisms remain unclear. In this study, we examine polyethylene and poly(lactic acid) SOM processes via mineralization incubation. Accordingly, evaluated changes carbon dioxide (CO2) methane (CH4) production. An O2 planar optical sensor was used to detect temporal behavior dissolved during incubation determine microscale oxygen heterogeneity caused by microplastics. Additionally, (DOM) were using a combination spectroscopic approaches ultrahigh-resolution mass spectrometry. Microplastics increased cumulative CO2 emissions 160–613%, whereas CH4 dropped 45–503%, which may be attributed oxygenated porous habitats surrounding Conventional biodegradable changed quantities carbon. microplastic treatments, DOM with more polar groups detected, suggesting higher level electron transport. addition, there positive correlation between concentration, electron-donating ability, emission. These findings suggest that facilitate modifying microenvironments, transport capability. study provides new insights into impact dynamics.

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.

Microplastic-derived dissolved organic matter (MP-DOM) exerts great effects on carbon pool and its environmental behaviors in natural waters due to increasing amounts of uncontrolled plastic disposal. However, systematic understanding chemical composition impacts MP-DOM aquatic systems was limited. In this work, the molecular structures derived from diverse characterization methods were examined synthesized provide a basis for their processes. Additionally, those factors affecting quantity quality released (e.g., types, water environments, external weathering conditions) reviewed. Furthermore, including biological degradation, adsorption mineral surfaces, interaction with pollutants, as well comprehensively summarized. Finally, we outlooked future research directions studies, aiming contribute deeper mechanisms control pollution through analysis MP-DOM. This review provides information further impact microplastics water, which might have consequences fluxes biogeochemical metal contaminants.

Abstract An estimated 258 million tons of plastic enter the soil annually. Joining persistent types microplastic (MP), there will be an increasing demand for biodegradable plastics. There are still many unknowns about pollution by either type, and one large gap is fate composition dissolved organic matter (DOM) released from MPs as well how they interact with microbiomes in agricultural systems. In this study, polyethylene MPs, photoaged to different degrees, virgin polylactic acid were added at levels incubated 100 days address knowledge gap. We find that, upon MP addition, labile components low aromaticity degraded transformed, resulting increased oxidation degree, reduced molecular diversity, changed nitrogen sulfur contents DOM. Terephthalate, acetate, oxalate, L-lactate DOM 4-nitrophenol, propanoate, nitrate major molecules available microbiomes. The bacteria involved metabolism mainly concentrated Proteobacteria, Actinobacteriota, Bacteroidota, fungi Ascomycota Basidiomycota. Our study provides in-depth understanding microbial transformation its effects evolution soils.

The increasing demand for sustainable alternatives to conventional plastics has propelled the interest in bioplastics. While numerous studies have showcased their environmental advantages, particularly reducing global warming potential and fossil fuel usage, comprehensive reviews on holistic impacts of bioplastics throughout life cycle are scarce. This paper aims fill this gap by critically evaluating sustainability bioplastics, from production disposal. We find that impact is influenced feedstock choices, processing methods, disposal practices. Although intensive agriculture can cause acidification eutrophication as well incomplete biodegradation may lead formation bio-micro/nano-plastics, generally present a lower burden than traditional plastics, evidenced reduced carbon footprint enhanced biodegradability, which contributes decreased plastic waste. Importantly, positively affect soil dynamics, underscoring role promoting agricultural management advocate future Life Cycle Assessment develop inventory database enabling more thorough evaluation impacts. research provides critical insights policymakers viability
