| 1 | Occurrence of polybrominated diphenyl ethers in fish and shellfish downstream from electronic-waste recycling plants显示文摘We measured 39 polybrominated diphenyl ethers (PBDEs) in the muscle tissue of three species of fish (Sciaenops ocellatus,Sparus macrocephalus,and Lateolabrax japonicus) and four species of shellfish (Tegillarca granosa,Cyclina sinensis,Sinonovacula constricta,and Ostrea cucullata) that were collected downstream of electronic-waste recycling plants in Taizhou,China.A total of 24 PBDE congeners (PBDE 24) in the samples were detected.The PBDE 24 (total PBDE) ranged from 545.4 to 1688.7 ng/kg ww (wet weight).The mean PBDE 24 concentration was 1382.6 ng/kg ww in fish and 858.1 ng/kg ww in shellfish.The lower brominated congeners were detected at relatively high concentrations in all species.The penta-products,produced from e-waste,were found at relatively low levels.A principal component analysis suggested a significant correlation among di-,tri-,tetra-,and hepta-BDEs for the three species of fish.Similarly,we found a significant correlation between mono-and tri-BDEs in the shellfish.Our results suggested that the processes of PBDE metabolism and elimination were similar in both fish and shellfish.In addition,the primary source of PBDEs appeared to be from the debromination of high brominated PBDEs. | Jinhua Jiang Shidi Shi Tao Chen | 2010 | Journal of Environmental Sciences2010，22，5： | 3 |
