Abstract
The role of marine plastic debris and microplastics as a carrier of hazardous chemicals in the
marine environment is an emerging issue. This study investigated expanded polystyrene (EPS,
commonly known as styrofoam) debris, which is a common marine debris item worldwide, and
its additive chemical, hexabromocyclododecane (HBCD). To obtain a better understanding of
chemical dispersion via EPS pollution in the marine environment, intensive monitoring of
HBCD levels in EPS debris and microplastics was conducted in South Korea, where EPS is the
predominant marine debris originate mainly from fishing and aquaculture buoys. At the same
time, EPS debris was collected from 12 other countries in the Asia-Pacific region, and HBCD
concentrations were measured. HBCD was detected extensively in EPS buoy debris and EPS
microplastics stranded along the Korean coasts, which might be related to the detection of a
quantity of HBCD in non-flame-retardant EPS bead (raw material). HBCD was also abundantly
detected in EPS debris collected from the Asia-Pacific coastal region, indicating that HBCD
contamination via EPS debris is a common environmental issue worldwide. Suspected tsunami
debris from Alaskan beaches indicated that EPS debris has the potential for long-range transport
in the ocean, accompanying the movement of hazardous chemicals. The results of this study
indicate that EPS debris can be a source of HBCD in marinmon marine debris item worldwide, and
its additive chemical, hexabromocyclododecane (HBCD). To obtain a better understanding of
