[Basin Distribution and Ecological Risk of Microplastics in Surface Water Bodies in China].
A comprehensive analysis of data from China's ten major river basins (2014–2023) found microplastic contamination in rivers, lakes, reservoirs, and estuaries across the country, with microplastic abundance strongly correlating with population density and economic output. Polypropylene and polyethylene were the dominant polymers, and the Haihe River Basin near Beijing was classified as high ecological risk. The study also highlighted a major data gap: far less is known about microplastics in China's less-populated northwestern regions. These findings provide a national-scale picture of where microplastic pollution is most severe and what types of plastics are driving the ecological risk.
