Occurrence and characteristics of microplastics in water and sediment samples along the red river to the gulf of tonkin, vietnam

Summary

This study characterized the occurrence and properties of microplastics in water and sediment samples along the Red River from inland Vietnam to the Gulf of Tonkin, mapping contamination levels across a major river system draining into the South China Sea. The findings help establish the scale of plastic inputs from Southeast Asian river systems, which are among the world's largest contributors to ocean plastic pollution.
