Microplastics can Alter the Nitrogen Cycle in Surface Flow Constructed Wetlands
AI summary Read the abstract
Both conventional PVC and biodegradable PLA microplastics disrupted nitrogen cycling in constructed wetlands, with PVC causing ammonium accumulation and PLA acting as a carbon source, while both enhanced biofilm formation and enzyme activities at higher concentrations. These polymer-specific effects on nitrogen dynamics reveal that microplastic contamination poses distinct and complex threats to the water treatment functions of natural and engineered wetlands.
Impact of Microplastics on Microbial Community Composition and Diversity in Surface Flow Constructed Wetland Sediments
AI summary Read the abstract
A study of conventional PVC and biodegradable PLA microplastics in constructed wetland sediments found both types altered microbial diversity and community composition, with PVC enriching denitrifying bacteria and PLA promoting methanogenic pathways at concentrations as low as 1%. These microbial shifts in wetland sediments could disrupt nitrogen and carbon cycling in ecosystems that serve as critical water quality filters.
Effects of microplastics on carbon and nitrogen cycling in coastal wetlands: A critical meta-analysis
AI summary
This meta-analysis of over 1,000 data points from 34 studies found that microplastics significantly altered certain carbon and nitrogen cycling indicators in coastal wetlands under laboratory conditions, but tidal simulation experiments more representative of real environments showed no significant effects. The findings caution against over-interpreting lab results and highlight that tidal dynamics and vegetation factors are often missing from experimental designs.
Microplastics in Wetland Ecosystem: A Complex Nexus and Way Forward
AI summary Read the abstract
This review examines the distribution, fate, and ecological impacts of microplastics in wetland ecosystems, which serve as both sinks and potential secondary sources of microplastic contamination. Wetlands filter water supplies and support biodiversity, so microplastic accumulation there directly threatens aquatic food webs, drinking water quality, and the communities that depend on these ecosystems.
Recent advances towards micro(nano)plastics research in wetland ecosystems: A systematic review on sources, removal, and ecological impacts
AI summary Read the abstract
Wetland ecosystems act as important sinks for micro- and nanoplastics, which were found to cause ecotoxicological effects on wetland plants, animals, and microbial communities, including shifts in microbial composition relevant to pollutant removal. Micro/nanoplastics exposure also affected conventional pollutant removal efficiency and greenhouse gas emissions from wetland systems.
