Microplastics affect ecosystem multifunctionality: Increasing evidence from soil enzyme activities

Land Degradation and Development, Journal Year: 2024, Volume and Issue: 35(15), P. 4379 - 4405

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.

ABSTRACT Microplastics and antibiotics are emerging pollutants that accumulate extensively in soils, both exerting adverse effects on soil ecosystems. The mechanisms underlying the combined of microplastics microbial metabolism remain insufficiently understood. Therefore, we evaluated individual different types (non‐degradable polyethylene biodegradable polylactic acid) an antibiotic (oxytetracycline) characteristics. Our results showed community was primarily limited by nitrogen under either or treatments; whereas it phosphorus treatments. All treatments, except for non‐biodegradable microplastic treatment, significantly alleviated carbon limitation ( p < 0.01), with effect being particularly pronounced treatments involving antibiotics. Notably, increased use efficiency 0.05). were influenced type their interaction antibiotics, highlighting complex nature these environmental pollutants. This study provided empirical basis understanding exposure co‐exposure to biodegradable/non‐biodegradable metabolism.
