Microplastics and heavy metal contamination frequently co-occur in stormwater filtration systems, where their interactions may potentially compromise nitrogen removal. Current research on microplastics Cd predominantly focuses soils constructed wetlands, with limited attention given to systems. In this study, the single synergistic effects of aged polyethylene (PE) cadmium (Cd) infiltration systems were investigated from perspectives removal, microbial community structures, predicted functional genes cycling. Results showed that PE demonstrated stronger inhibition NO3−–N removal than Cd. Low-level (PE content: 0.1% w/w) Cd-contaminated inhibitory effect high-level 5% w/w). The mean efficiency under combined Cd50 (Cd concentration: 50 μg/L) PE5 during sixth rainstorm event was 1.04 34.68 times other scenarios. Metagenomic analysis identified keystone genera (Saccharimonadales, Enterobacter, Aeromonas, etc.), critical transformation pathways (nitrate reduction ammonium, denitrification, fixation, nitrification) govern system performance. most pronounced nitrification/denitrification enzymes beyond nitrite oxidase nitrate reductase. These mechanistic findings advance our understanding co-contaminant

Recent Insights into Microplastic Pollution and Its Effects on Soil Carbon: A Five-Year Ecosystem Review

Microplastics, Год журнала: 2025, Номер 4(2), С. 18 - 18

The widespread presence of microplastics (MPs) is growing concern for both the scientific community and public. Contemporary research increasingly focuses on ecosystem transformation global climate change. We conducted a literature review, consisting 46 studies, to investigate consequences MPs’ influence carbon cycle in different soil types across various ecosystems. MPs can affect cycling compounds other biogenic elements by impacting microbiome, enzyme activity, plant growth, litter decomposition, more. majority authors report increased CO2 and/or CH4 emissions soils containing MPs. However, some studies demonstrate opposite or neutral result, outcomes differ even within single study depending type type, form, size used. Further clarification development our understanding regarding impact ecosystems remain crucial, taking into account inclusion as wide variety possible future research.
