The aims of this project were (1) to determine concentrations of chlordane, toxaphene, total mercury, organotin compounds, phthalates, polybrominated diphenyl ethers, nonylphenol and bisphenol A in sediments and fishes of 11 rivers (Tamsui River, Tahai River, Hsintien River, Toucain River, Tachia River, Beigang River, Hsiukuluan, Keelung River, Ka-Ya River, Putsu River, and General river) in Taiwan; (2) to apply the investigation results for policy-making of toxic substance management; and (3) to update the databases of environmental distribution of toxic substances.There were 99 sediment and fish samples collected from 11 rivers (each river collected 6 sediment and 3 fish samples) in this year. Fourteen toxic substances and seven related compounds were analyzed in each sample. There were 1,341 analytical data obtained, including 894 data from sediments and 477 data from fish samples. In sediment samples, the measured mean concentration and range of toxic substances were ND-<2.0 ug/kg dw for chlordane, <2.0 (ND-4.7) ug/kg dw for toxaphene, 0.177 (0.021-0.856) mg/kg dw for total mercury, <0.05 (ND-0.06) mg/kg dw for DMP, <0.05 (ND-0.08) mg/kg dw for DEP, 0.08 (<0.05-0.34) mg/kg dw for DBP, 0.08 (<0.05-0.43) mg/kg dw for BBP, 3.5 (0.08-23.6) mg/kg dw for DEHP, ND mg/kg dw for DOP, <0.05 (ND-0.19) mg/kg dw for TBT, ND for DBT, <0.05 (ND-0.05) mg/kg dw for MBT, <0.05 (ND-0.21) mg/kg dw for MPhT, <0.05 (ND-0.09) mg/kg dw for DPhT, <0.05 (ND-0.08) mg/kg dw for TPhT, 39.5 (0.651-356) ug/kg dw for total PBDEs, 1.53 (0.01-19.6) mg/kg dw for nonylphenol, and 22.6 (0.37-156) ug/kg dw for bisphenol A. In fish samples, the measured mean concentration and range of toxic substances were <1.0 ug/kg ww for chlordane, 2.4 (<1.0-10.2) ug/kg ww for toxaphene, 0.063 (0.025-0.179) mg/kg ww for total mercury, ND-<0.03 mg/kg ww for DMP, <0.03 (<0.03-0.20) mg/kg ww for DEP, 0.05 (<0.03-0.23) mg/kg ww for DBP, 0.03 (<0.05-0.15) mg/kg ww for BBP, 0.23 (<0.03-1.7) mg/kg ww for DEHP, ND-<0.03 mg/kg ww for DOP, <0.01 (ND-0.05) mg/kg ww for TBT, ND-<0.01 mg/kg ww for DBT, 0.05 (ND-0.57) mg/kg ww for MBT, <0.01 (ND-0.02) mg/kg ww for MPhT, <0.01 (ND-0.04) mg/kg ww for DPhT, <0.01 (ND-0.03) mg/kg ww for TPhT, 4.99 (0.288-23.3) ug/kg ww for total PBDEs, 76.2 (9.62-277)ug/kg ww for nonylphenol, and 1.13 (<0.625-12.3) ug/kg ww for bisphenol A. For toxic substances with high levels found in the aquatic environment, such as DEHP, PBDEs, nonylphenol and bisphenol A, we suggested to promote their control rank and strengthen the control measures. It is necessary to consult and discuss with related administrations and departments in order to speed up the establishment or amendment of suitable control measures for products containing these toxic substances. The 1,341 analytical data analyzed in this year were updated to the database searching system for the distribution of toxic substances investigated by EPA, Taiwan. The investigation results from 596 English and Chinese journal articles were input into the database searching system for the distribution of toxic substances in many countries.
