微塑料污染已成为全球生态系统最严重的威胁之一,其不仅对陆地和海洋生态系统、生物多样性和人体健康产生影响,还会通过影响土壤有机碳固定扰动全球气候。土壤中微塑料可以直接参与碳循环或间接影响理化性质和微生物群落来影响土壤有机碳周转过程。本文从微塑料影响土壤有机碳测定,以及微塑料介导的有机碳形成过程、矿化和稳定过程等方面,阐明了微塑料对土壤有机碳库的影响,并深入探讨了微塑料调控土壤有机碳循环的可能机制。未来需从微塑料源碳的精准识别、碳过程关键微生物作用机制、多因素影响下碳循环过程等方面开展进一步的研究工作。

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.

Biodegradable plastics, as alternatives to conventional waste are increasingly applied across various fields. However, the ecological risks associated with widespread use of biodegradable plastics remain unclear. Additionally, tend age in environment, leading changes their physicochemical properties. The brought by aging microplastics have also been scarcely studied. In this study, we selected (PE-MPs), (PLA-MPs), and aged (aging-PLA-MPs) explore effects on rhizosphere soil environment rice. results showed that reduced N P content, PE slightly increasing DOC while PLA aging-PLA significantly increased 21.13 24.04%, respectively. Microplastics decreased enzyme activity, having a somewhat stimulatory effect activity compared PLA. Furthermore, bacterial diversity index altered community structure dominant species, content FDA hydrolase being main factors influencing community. Bacteria were most sensitive PLA, stability microbial network decreased, although negative impact This study contributes our understanding posed processes environment.
