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.
为了研究韩国多溴二苯醚（PBDEs）的背景水平，对高城湾周围的小溪和潮间带沉积物中的 PBDEs 浓度进行了测量。小溪沉积物中 PBDEs 的总浓度（Σ19PBDE）范围为 0.18 至 13.95ng/g 干重，约为潮间带沉积物的两倍。PBDE 浓度比韩国和其他国家工业活跃地区报道的浓度低两个数量级。BDE 209 是主要的同系物，分别占小溪和潮间带沉积物中总 PBDEs 的 79.0%和 78.5%。这与韩国大量使用十溴二苯醚以及十溴二苯醚非常高的辛醇-水分配系数相一致。小溪和潮间带沉积物中 PBDEs 的相对组成相似。BDE 209 和 Σ19PBDE 与总有机碳呈统计学上显著相关，而低溴代同系物与总有机碳的相关性较差。
