Effects of polyethylene microplastics and heavy metals on soil-plant microbial dynamics
This study examined how polyethylene microplastics interact with heavy metals in soil and found that microplastics significantly reduced plant growth while altering soil enzyme activity and microbial communities. The combination of microplastics and heavy metals disrupted nutrient cycling in the soil in ways that were different from either pollutant alone. These findings suggest that microplastic contamination in agricultural soil could affect crop nutrition and food production.
Polyethylene microplastics alter soil microbial community assembly and ecosystem multifunctionality
Researchers studied how polyethylene microplastics at different concentrations affect soil microbial communities and overall ecosystem function in a maize growing system. They found that higher concentrations of microplastics shifted microbial community composition, reduced beneficial bacteria involved in nutrient cycling, and impaired multiple soil ecosystem functions simultaneously. The study suggests that microplastic contamination in agricultural soils can undermine the biological processes that support healthy crop growth.
Plant-driven strategies for mitigating microplastic pollution in agricultural ecosystems
Researchers review how microplastics damage agricultural soils and crops — disrupting soil structure, starving plants of nutrients, and triggering oxidative stress — and explore plant- and microbe-based strategies like root-associated bacteria and biochar amendments as promising but underexplored tools for cleaning up plastic-contaminated farmland.
Effect of emerging contaminants on soil microbial community composition, soil enzyme activity, and strawberry plant growth in polyethylene microplastic-containing soils
Researchers found that emerging contaminants altered soil microbial community composition and enzyme activity, but these effects were suppressed when HDPE microplastics were also present in the soil, suggesting microplastics may modulate how soils respond to chemical contaminants.
Extraction of Polyethylene and Polypropylene Microplastic from Agriculture Soil
