전국 주요 양식장 퇴적물과 양식생물 내 PBDEs와 대사체 분포 = Distribution of Polybrominated Diphenyl Ethers and their Metabolites in the Sediment and Organisms Collected from Korean Coastal Aquaculture Farms

다국어 초록 (Multilingual Abstract)

In this work, the concentrations of several polybrominated diphenyl ethers (PBDEs) and methoxylated BDEs (MeO-BDEs) in the sediment and organisms collected from aquaculture farms along the Korean coasts were evaluated in order to study their occurrence and distribution. The concentrations of the PBDE and MeO-BDE congeners were measured by using a high-resolution gas chromatograph coupled to a mass spectrometer based on selected ion monitoring. It was found that the concentrations of the PBDEs and MeO-BDEs in the sediment and organisms from the southern coasts were higher than those found in samples from the western and eastern coasts (p<0.05). Similar results were obtained for the persistent organic pollutants (POPs) such as polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDD/Fs), and dioxin-like polychlorinated biphenyls (DL-PCBs), indicating a similar contamination source or environmental behavior of these compounds. Relatively higher concentrations of PBDEs and MeO-BDEs were found in bivalves and urochordates as compared to those determined in seaweed, which could be related to their lipid contents. Deca-BDE and tetra-MeO-BDE were the predominant homologues of PBDE and MeO-BDE groups present in both the sediment and the organisms, respectively. Meanwhile, the concentration of MeO-BDEs appeared to be higher than that of PBDEs, which might be attributed to both the natural formation of MeO-BDEs in the marine ecosystem and the transformation of PBDEs to MeO-BDEs.
