Abstract Microplastics (MPs) as emerging contaminants have a global occurrence, including both terrestrial and marine ecosystems. Soil enzymes contribute to maintaining ecosystem multifunctionality, for example, nutrient cycling, organic material decomposition, carbon climate regulation. Our present review highlights the impacts of MPs on soil enzyme activities, influencing factors, underlying mechanisms. Increasing findings confirm that can change activities range involved in biogeochemical cycling C N. However, current results are highly controversial. The effects vary from significant nonsignificant dependent polymer type, biodegradability, dosage, size, shape, aging degree MPs, exposure conditions. Compared traditional biodegradable generally show more pronounced effects. via different pathways. On one hand, directly structure, leading alterations activity. other create unique habitats, provide sources specific functional microbes producing enzymes, release plastic additives pollutants disturbing production these enzymes. Furthermore, alter physicochemical biological properties, availability substrates, plants fauna, regulating their functions. In conclusion, regulate pose profound impact multifunctionality.

Ecological and Health Risk Mediated by Micro(nano)plastics Aging Process: Perspectives and Challenges

Environmental Science & Technology, Год журнала: 2025, Номер unknown

Опубликована: Март 19, 2025

Aged micro(nano)plastics (MNPs) are normally the ultimate state of plastics in environment after aging. The changes physical and chemical characteristics aged MNPs significantly influence their environmental behavior by releasing additives, forming byproducts, adsorbing contaminants. However, a systematic review is lacking on effects ecological human health regarding increasing but scattered studies results. This Review first summarizes unique methods for quantifying aging degree. Then we focused potential impacts organisms, ecosystems, health, including "Trojan horse" under real conditions. Through combining meta-analysis analytic hierarchy process (AHP) model, demonstrated that, compared to virgin MNPs, would result biomass decrease oxidative stress increase organisms lead total N/P greenhouse gas emissions ecosystems while causing cell apoptosis, antioxidant system reaction, inflammation health. Within framework risk assessment, used quotient (RQ) physiologically based pharmacokinetic (PBK) models as examples illustrate importance considering degree data acquisition, model building, formula evaluation. Given risks our urgent call more understand hazards real-world environments.
