Abstract Soil microplastics (MPs) pollution has garnered considerable attention in recent years. The use of biodegradable plastics for mulching led to significant quantities plastic entering agro-ecosystems. However, the effects polylactic acid (PLA) on meadow soils remain underexplored. This study investigates impacts PLA varying particle sizes and concentrations soil physicochemical properties, enzyme activities, microbial communities through a 60-day incubation experiment. PLA-MPs increased pH, organic matter (SOM), total nitrogen (TN) available potassium (AK) content, as well enhanced activities superoxide dismutase (S-SOD), peroxidase (S-POD), catalase (S-CAT), β-glucosidase(S-β-GC) urease (S-UE) activities. Conversely, decrease alkaline phosphatase (S-ALP) activity was observed. influence properties more pronounced with larger sizes, whereas smaller particles had greater effect Additionally, an increase abundance Acidobacteriota, Chloroflexi, Gemmatimonadota, while Proteobacteria, Actinobacteriota, Patescibacteria declined. Mental test analysis indicated that AK, S-UE, S-β-GC are primary factors influencing community composition. Phylogenetic Investigation Communities by Reconstruction Unobserved States (PICRUSt2) demonstrated modify bacterial metabolic pathways. Our results suggest size concentration differentially affect nutrients structure function, observed at higher concentrations.

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.

Microplastics (MPs) are of great interest for study because they accumulate in environmental systems, such as terrestrial ones, which include agricultural soils. Unfortunately, recent years, due to the COVID-19 pandemic, many face masks have been discarded environment, causing an increase this type MP. This accumulation can influence physicochemical and biological properties soil derived from its microbial activity. In present study, different concentrations MPs commercial polypropylene (PP) were mixed with soil. Four treatments following MP studied: T1: 0%, T2: 0.5%, T3: 1%, T4: 5% w w−1. C N mineralization experiments carried out over time at microcosm level, where physicochemical, enzymatic ecophysiological indicators analyzed. Based on analyzed indicators, a quality index called Unified Weighted Additive Index (SQIu) was developed. The resulting SQIu showed Nmin indicator closest relationship soils MPs. Once determined, T4 treatment significant differences (p≤0.05) respect control, presenting higher value. importance conducting more research dynamics types, sizes, help establish strategies measure effects local, national, international levels.
