Microplastic abundance, distribution, and composition in the surface water and sediments of the Yangtze River along Chongqing City, China
AI summary Read the abstract
Microplastics were found throughout surface water and sediments of the Yangtze River in Chongqing, with abundances up to 204 particles per liter in water and 583 per kilogram in sediment, dominated by small fibers under 0.7 mm. The prevalence of fine fiber microplastics in one of China's most important waterways signals widespread contamination with implications for drinking water quality and aquatic ecosystem health.
Seasonal dynamics, tidal influences, and anthropogenic impacts on microplastic distribution in the Yangtze River estuary: A comprehensive characterization and comparative analysis
AI summary Read the abstract
Researchers studied microplastic pollution in the Yangtze River estuary and found average concentrations of about 1 particle per cubic meter of surface water, mostly polystyrene, polypropylene, and polyethylene. Microplastic levels were nearly twice as high during flood season compared to dry season and decreased with distance from urban centers. These findings highlight how population density and seasonal water flow influence microplastic distribution in major waterways.
Distribution, source, and sink of microplastics in the nearshore-estuarine systems of the South China Sea basin
AI summary Read the abstract
This review synthesizes data on microplastic distribution, sources, and sink dynamics across rivers, nearshore zones, and estuaries of the South China Sea, identifying river inputs, industrial discharge, aquaculture, and shipping as major pollution drivers. The findings are significant because the South China Sea's densely populated coastal margins represent a major pathway through which microplastics enter marine ecosystems and regional seafood supplies.
Occurrence and Driving Mechanism of Microplastics in River-connected Lake of the Mid-lower Yangtze River Basin
AI summary Read the abstract
Researchers analyzed 19 studies on microplastic pollution in river-connected lakes of China's Yangtze River Basin and found average concentrations of 11,854 items/m³ in water and 649 items/kg in sediment, with human activities such as wastewater discharge and economic development identified as primary drivers through GeoDetector modeling.
Tidal variability and microplastics distribution: source analysis in Dongshan Bay beach sediments, South China
AI summary Read the abstract
A four-site study of Dongshan Bay beach sediments in South China found microplastic concentrations ranging from 7.4 to 283.1 items/kg, with tidal dynamics strongly influencing distribution — higher loads near estuaries at high tide and coastal accumulation at low tide — and statistical analysis pointing to fishing and packaging industries as the dominant sources. Tidal forcing emerges as a key control on microplastic redistribution in coastal sediments, complicating source attribution and remediation planning for fishery-intensive coastlines.
