Abstract
This study investigated the levels and profiles of chemicals (both sorbed and additive

chemicals) in various types of plastic particles (in size and shape) collected from the

Korean coastal waters. PCBs, DDTs, HCHs, HCB, PAHs, PBDE and HBCDs, phthalates, UV

stabilizers, and antioxidants were widely detected in field microplastic samples. Except for

expanded polystyrene (EPS) samples, phthalates showed the highest concentrations in most

of size classes (< 1 mm, 1 to 5 mm, and > 5 cm) and shapes (fragments, fibers, and pellets),

followed by HBCDs, UV stabilizers, antioxidants, PAHs, PBDEs, PCBs and DDTs. PBDE

was high in fragments, HBCDs and PAHs were high in foams (EPS), and antioxidants

were high in fibers. Sorbed chemicals were relatively high in small particles (< 1 mm),

while additives were relatively high in large particles (> 5 cm). Based on the chemical

concentrations measured in microplastics, the potential intake of chemicals in microplastics

by seafood consumption was estimated. Even through a worst case scenario is followed, the

estimated exposure via microplastics in seafood is less than 1 percent of the total dietary

intake of those chemicals except for HBCD.HBCDs, phthalates, UV
