As plastic debris breaks down to small plastic particles in the environment, it becomes available for ingestion by a wide range of small marine organisms. Among them, bivalves are important monitoring species because they are filter feeders that that filter large amounts of seawater and therefore likely to expose to microplastics present in the water column. Additionally, bivalves are one of the popular seafood for human consumption. This study investigated microplastic contamination in wild and commercial bivalves (oysters and mussels) from the Korean coats and fishery markets, respectively. Wild bivalves were collected from ten locations along the Korean coasts and commercial bivalves are bought from fisherymarkets in three major cities. Microplastic pollution was widespread in both wild and commercial bivalves from Korea with detection frequency of 95%. The mean concentration of microplastics was 0.84 ± 1.30 particles / g (4.57 ± 7.65 particles / individual) in wild bivalves and 0.10±.0.09 particles / g (0.73 ± 0.70 particles / individual) in commercial bivalves. The relatively low levels of microplastics in commercial bivalves might be due to the depuration of ingested particles during transportation and storage. In both samples, fragment (> 80%) was the dominant type of microplastic, and the most common size class is 100
