LEVELS OF PCDDS, PCDFS, DIOXIN-LIKE PCBS, AND PBDES IN FISH SAMPLES FROM RIVERS AND ESTUARIES IN TAIWAN

The concentrations of polychlorinated dibenzo-p-dioxin (PCDDs), polychlorinated dibenzo- p-furan (PCDFs), dioxin-like polychlorinated biphenyls (DLPCBs), and polybrominated diphenyl ethers (PBDEs) were measured in fifty-nine fish samples collected from rivers and estuaries in Taiwan. Determination of PCDDs/PCDFs/ DLPCBs and PBDEs was carried out using HRGC/HRMS. For all fish of all species from all sampling areas, the concentration range for PCDDs/PCDFs and DLPCBs World Health Organization Toxic Equivalent (WHO-TEF) were 0.024 ~ 1.02 pg WHO-TEQ/g wet weight and 0.023 ~ 14.1 pg WHO-TEQ/g wet weight respectively. The concentration range for PBDEs were 12.1 ~ 380 ng/g lipid weight, with BDE-47>BDE-154>BDE-100 ~ BDE-99>BDE-153>BDE-183. The highest concentrations of both PCDDs/PCDFs and PBDEs were found in the area of Erren river and the highest concentrations of DLPCBs was found in Dahan river. The average recoveries of the 13C-labelled internal standards for PCDDs/PCDFs, Dioxin-like PCBs and PBDEs were in the range of 63 ~ 95 %, 54 ~ 78 % and 37 ~ 126 % respectively. The average recoveries of the method blank spike samples for PCDDs/PCDFs, Dioxin-like PCBs and PBDEs were in the range of 86 ~ 99 %, 105 ~ 112 % and 86 ~ 119 % (133% for BDE-209) respectively.
