  • Title: Background level and composition of polybrominated diphenyl ethers (PBDEs) in creek and subtidal sediments in a rural area of Korea.

    Journal: Sci Total Environ; 2014 Feb 01; 470-471():1479-84. PubMed ID: 23870498.
    Abstract:
    To study background levels of polybrominated diphenyl ethers (PBDEs) in Korea, concentrations of PBDEs were measured for creek and subtidal sediments around Goseong Bay. Total concentrations of PBDEs (Σ19PBDE) in creek sediments ranged from 0.18 to 13.95 ng/g dry weight and were about twice those in subtidal sediments. PBDE concentrations were about two orders of magnitude lower than those reported in industrially active regions of Korea and other countries. BDE 209 was a major congener, accounting for 79.0% and 78.5% of total PBDEs in creek and subtidal sediments, respectively. This is consistent with the high consumption of deca-BDE in Korea and the very high octanol-water partition coefficient of deca-BDE. The relative compositions of PBDEs in creek and subtidal sediments were similar. BDE 209 and Σ19PBDE had statistically significant correlations with total organic carbon, the lower brominated congeners had a poor correlation with total organic carbon.
