Researchers applied a mass-balance modeling approach to assess marine plastic pollution in the South China Sea, finding critical data gaps on plastic inputs, transfer rates, and sink terms that prevent accurate quantification of this recognized global plastic hotspot.
Spatial Distribution and Composition of Surface Microplastics in the Southwestern South China Sea
Researchers investigated the spatial distribution, morphology, and polymer composition of surface microplastics in the southwestern South China Sea during a 2018 cruise, finding an average abundance of 0.072 particles/m3 with fibers and fragments dominating, and PET, PVC, and cellophane as the most prevalent polymers, with higher concentrations near the Nansha Islands.
Plastic waste occurrence on a beach off southwestern Luzon, Philippines
Researchers documented plastic waste on a beach in southwestern Luzon, Philippines, finding high levels of macroplastic litter and establishing baseline microplastic contamination data for a country identified as one of the largest contributors of plastic waste to the ocean.
A perspective study on occurance, impacts and sources of microplastics in the marine environment of south China Sea and Gulf of Thailand
A synthesis of published data on microplastics in the South China Sea and Gulf of Thailand identified the Pearl River and Mekong River as major plastic inputs, with the Gulf of Thailand showing medium plastic abundance levels, and called for improved management strategies for these sensitive regions.
[Distribution Characteristics of Microplastics in Surface Water and Sediments of Haizhou Bay, Lianyungang].

The spatial distribution of microplastic in the sands of a coral reef island in the South China Sea: Comparisons of the fringing reef and atoll
Microplastic abundance in coral reef island sands of the South China Sea was measured at fringing reef sites (90–530 items/kg) and atoll sites (60–610 items/kg), with the lower-human-activity Xisha Islands atoll showing higher concentrations attributed to oceanic current accumulation. The study reveals that even remote coral reef ecosystems are contaminated with microplastics and that oceanographic factors can outweigh local human activity.
