Abstract
The role of plastic marine debris as a carrier of hazardous chemicals in the marine environment is an emerging issue. This study focused on expanded polystyrene (EPS, commonly known as Styrofoam) debris, which is a common marine debris item worldwide, and its additive chemical, hexabromocyclododecane (HBCD). To identifythe potential of EPS debris for the transfer and dispersion of chemicals to the pristine marine environment, two islands located in the southern part of Koreawith very different EPS debris pollution levels (one contaminated islands and one non-contaminated island) were selected as study sites, and the exposure levels of HBCDs in marine organisms inhabiting each island were assessed and compared. Along with HBCDs, a typical sorbed chemical, polychlorinated biphenyl (PCB) were analyzed for comparison. No difference was observed in PCB levels in

organisms such as oyster, limpet, and gastropods from two islands, while the HBCD concentration was significantly higher in organisms inhabiting contaminated islands than those inhabiting non-contaminated island (Mann?Whitney, p< 0.05). The result of this study indicates that EPS marine debris has a strong potential for source and carrier of plastic additives, HBCDs, in the marine environment.
