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.

Global meta-analysis reveals differential effects of microplastics on soil ecosystem

The Science of The Total Environment, Journal Year: 2023, Volume and Issue: 867, P. 161403 - 161403

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.

Global Responses of Soil Carbon Dynamics to Microplastic Exposure: A Data Synthesis of Laboratory Studies

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.
