ClearThe Environmental Impacts and Remediation Strategies of Microplastics in Aquatic Sediments
This review comprehensively examines microplastic contamination in aquatic sediments worldwide, where concentrations are typically three to five orders of magnitude higher than in the water above — making sediments the dominant reservoir of plastic pollution in rivers, lakes, and oceans. The paper covers how microplastics enter and accumulate in sediments, how they bind to other contaminants like heavy metals and pesticides, and the ecological risks to bottom-dwelling organisms. It identifies major gaps in monitoring and calls for standardized methods to make global comparisons possible.
