CONTAMINATION LEVELS OF PCDDS, PCDFS AND NON-ORTHO CHLORINE SUBSTITUTED COPLANAR PCBS IN MILKFISH AND CRAB FROM CULTURE POND AND COASTAL AREA NEAR OPEN-AIR INCINERATION SITES FOR METAL RECLAMATION IN WAN-LI, TAIWAN, REPUBLIC-OF-CHINA

Samples of culture freshwater milkfish (Chanos chanos) from five ponds surrounding open-air waste incineration sites and from five markets i n southern Taiwan were analyzed for PCDDs, PCDFs and coplanar PCBs (Co -PCBs). The total TEQ concentration of three chemicals in fish meat wa s in a wide range of 0.195 to 153 pg/g wet weight. In addition, the bi oconcentration factors from sediment to fish meat and crab hepatopancr eas biota were arranged in order of Co-PCBs >> PCDFs > PCDDs and Co-PC Bs > PCDFs >> PCDDs, respectively.
