Biodegradable polymers are promoted as promising alternatives for conventional non-degradable plastics, but they may also negatively impact soil ecosystems. Here, we estimated the effects of biodegradable (polylactide (PLA) and polybutylene succinate (PBS)) non-biodegradable (polyethylene (PE) polystyrene (PS)) microplastics at a concentration 1% (w/w) on dissolved organic matter (DOM) in two types, black (BS) yellow (YS), by using fluorescence excitation-emission matrix spectroscopy ultrahigh-resolution Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR-MS). PBS significantly increased contents carbon (DOC) relative intensities protein-like components. The turnover rates DOM were statistically higher treatments (0.106 0.196, p < 0.001) than those other microplastic groups. FT-ICR-MS results indicated that more labile-active molecules preferentially obtained treatments, which be attributed to polymer degradation. showed no significant optical characteristics changed molecular compositions DOM. More labile observed BS samples treated with PE compared control, while decreased lability YS soil. distinct priming plastic-leached trigger changes different soils. This study provided important information further understanding processes.

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.

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.
