The Occurrence of Microplastics Pollution in the Surface Water and Sediment of Lake Chenghai in Southwestern China
This study measured microplastic pollution in the water and sediment of Lake Chenghai, a plateau lake in southwestern China. Researchers found microplastics at all sampling sites, with fibers and fragments being the most common types, mainly from synthetic clothing and plastic packaging. The findings show that even remote freshwater lakes used by local communities are contaminated with microplastics, raising concerns about drinking water safety.
Comprehensive analysis of microplastics in water, sediment and fish from a large recreational lake
Researchers surveyed microplastics in water, sediment, and fish from a large recreational lake in China, finding MPs across all sampled compartments with higher concentrations near tourist facilities and boat launch areas, raising concerns about human exposure through lake recreation and consumption of contaminated fish.
[Characterization of Microplastic Pollution of Sediments from Urban Lakes].
Sediments from urban lakes in Maanshan City, China contained microplastics in both spring and summer, with fragments and fibers as the most common types. Local industrial and domestic activities were identified as the likely sources, adding to evidence of widespread microplastic contamination in freshwater sediments.
Characteristic study of microplastics distribution and response to human activities in nine highland lakes in Yunnan province
Researchers characterized microplastic distribution patterns across nine highland lakes in Yunnan Province, China, examining abundance, morphology, and polymer types while investigating how human activities influence contamination levels across lakes with differing land-use pressures. The study found that microplastic abundance correlated with proximity to human settlements and agricultural activity, with fibers and fragments as the dominant morphotypes across the surveyed lakes.
Analysis on advances and characteristics of microplastic pollution in China’s lake ecosystems
Statistical data on microplastic pollution were compiled and analyzed for 86 lakes across China's lake ecosystems over the past five years, revealing widespread contamination with concentrations generally higher in lakes near urban and industrial areas. The review identifies China's heavily polluted eastern lake region as a priority for microplastic monitoring and management intervention.
Microplastics in surface waters of Dongting Lake and Hong Lake, China
Researchers sampled surface waters of Dongting Lake and Hong Lake in China and found microplastic contamination at both sites, with fibers as the dominant type and concentrations reflecting nearby human population density and land use.
Microplastics in Sediment and Surface Water of West Dongting Lake and South Dongting Lake: Abundance, Source and Composition
Microplastics were found in both surface water and sediments of West Dongting Lake and South Dongting Lake in China, with fibers and fragments as the dominant types and concentrations influenced by proximity to urban and agricultural land use. The study provides the first data on microplastic contamination in China's second-largest freshwater lake system.
Tracing Footprint and Risk of Microplastics and Microfibers in the Lakes across China
Researchers surveyed microplastic and microfiber contamination in the sediments of 102 lakes across China, identifying pollution sources and developing a new risk assessment index. They found contamination levels ranging widely and were able to separate microfiber pollution from microplastic pollution to better trace their origins. The study provides a large-scale snapshot of lake contamination and introduces a tool for evaluating ecological risk from these particles.
Distribution of microplastics in benthic sediments of Qinghai Lake on the Tibetan Plateau, China
Researchers mapped the distribution of microplastics in the bottom sediments of Qinghai Lake on the Tibetan Plateau, sampling from shore to center. The study found microplastics throughout the lake sediments even in this remote, high-altitude location, with abundance patterns influenced by factors such as tourism activity and water currents rather than simply decreasing from shore to center.

Levels And Distribution Characteristics of Microplastics In Water And Sediment of A Typical Shallow Lake In Northern China
Scientists measured microplastic levels in the water and sediment of Baiyangdian Lake, a shallow lake in northern China. They found between 1,000 and 20,000 microplastic particles per cubic meter of water and up to 2,200 particles per kilogram of sediment. Despite pollution control efforts, microplastics remain widespread in this lake ecosystem.

This study measured microplastic contamination in lakes across the Inner Mongolia Plateau and found levels ranging from 0.5 to 12.6 particles per liter in water, with polypropylene being the most common type. Lakes near farmland and human activity had the highest contamination, showing that agriculture and tourism are major sources of microplastic pollution. The findings are relevant because these lakes serve as water sources for surrounding communities.
