This project was to (1) determine concentrations of endosulfan, nonylphenol, bisphenol A, phthalates, organotins, hexabromocyclododecane (HBCD) and polychlorinated biphenyls (PCBs) in water, sediments and fishes of 10 rivers in Taiwan; (2) establish database for environmental distribution of toxic substances; (3) analyze the investigative results over the years, and then propose control measures of toxic substances for policy-making; and (4) update the results of environmental distribution of toxic substances in the handbook. There were 9 water and 60 sediment and 30 fish samples collected in this year. The total 1899 analyzed data were obtained. The mean concentration and concentration range of total PCBs in water and sediment samples from the three rivers each in the northern, central and southern Taiwan was ND and 1.19 (ND-9.33) ug/kg dw in the dry season. The mean concentration and concentration range of three HBCD diastereoisomers in sediment samples from the three rivers each in the northern, central and southern Taiwan in the dry and wet seasons was <0.200 (ND-0.893) ug/kg dw for a-HBCD, ND-<0.200 ug/kg dw for b-HBCD, <0.200 (ND-1.36) ug/kg dw for r-HBCD. The mean concentration and concentration range in fish samples was 0.138 (ND-0.453) ug/kg ww for a-HBCD, ND for b-HBCD, <0.050 (ND-0.229) ug/kg ww for r-HBCD. In sediment samples during the dry and wet seasons from 10 rivers in Taiwan, the mean concentration and concentration range of analyzed toxic substances was 261 (0.555-11,064) ug/kg dw for nonylphenol, 5.81 (ND-74.9) ug/kg dw for bisphenol A, <0.050 (ND-0.628) ug/kg dw for a-endosulfan, <0.050 (ND-0.723) ug/kg dw for b-endosulfan, 0.096 (ND-1.20) ug/kg dw for endosulfan sulfate, <0.05 mg/kg dw or ND for DMP and DEP, <0.05 (ND-0.07) mg/kg dw for DIBP, <0.05 (<0.05-0.07) mg/kg dw for DBP, <0.05 (<0.05-0.09) mg/kg dw for BBP, 0.52 (<0.05-3.5) mg/kg dw for DEHP, <0.05 (ND-0.06) mg/kg dw for DNOP, <2.5 (ND-5.8) mg/kg dw for DINP, <2.5 (ND-5.1) mg/kg dw for DIDP, ND for TBT, MPhT and TPhT, <0.04 (ND-0.15) mg/kg dw for DBT, <0.05 (ND-0.18) mg/kg dw for MBT, <0.04 (ND-0.06) mg/kg dw for DPhT. The mean concentration and concentration range in fish samples was 22.9 (ND-364) ug/kg ww for nonylphenol, 0.891 (ND-2.71) ug/kg ww for bisphenol A, <0.03 (ND-0.128) ug/kg ww for a-endosulfan, <0.03 (ND-0.184) ug/kg ww for b-endosulfan, 0.057 (ND-0.270) ug/kg ww for endosulfan sulfate, <0.03 mg/kg ww or ND for DMP, DEP, DIBP, BBP and DNOP, <0.03 (<0.03-0.03) mg/kg ww for DBP, 0.13 (<0.03-0.38) mg/kg ww for DEHP, <1.25 (ND-1.6) mg/kg ww for DINP, <1.25 (ND-1.8) mg/kg ww for DIDP, ND for TBT, DBT and MBT, <0.01 (ND-0.12) mg/kg ww for MPhT, <0.01 (ND-0.14) mg/kg ww for DPhT, <0.01 (ND-0.02) mg/kg ww for TPhT. The database searching system for concentrations of regulated toxic substances has been updated with the investigation results in this year.
