本計畫包含四項主要工作目標：(一)完成檢測10條河川、9種國際關注有毒污染物及19種持久性有機污染物或環境荷爾蒙物質之環境流布背景實地測量調查資料；(二)建立毒性化學物質環境流布檢測資料；(三)分析歷年毒性化學物質環境流布調查資料成果，並提具毒性化學物質因應管制措施建議及分析；(四)更新毒性化學物質環境流布調查成果手冊。本年度調查河川有淡水河本流、大漢溪、新店溪、八掌溪、急水溪、曾文溪、高屏溪、林邊溪、花蓮溪、卑南溪等10條河川。依調查物質環境流布特性分析水體、底泥或魚體樣本，共計完成枯水期及豐水期兩季各30個水體及30個底泥樣本，以及全年30個魚體樣本採樣。完成樣本檢測數據資料共計2,700筆，包括360筆水體樣本數據、1,632筆底泥樣本數據及708筆魚體樣本數據。10條河川之各項物質檢測平均濃度及範圍分別為，水體樣本中甲醛ND-0.00367 mg/L，四氯化碳、鄰-二氯苯、氯苯皆為ND，三氯甲烷及1,2-二氯乙烯為ND-<0.001 mg/L。底泥樣本中三氯甲烷<0.001 (ND-0.00964) mg/kg濕重；鄰-二氯苯及1,2-二氯乙烯皆為ND；氯苯ND-<0.001 mg/kg濕重；三價砷0.397 (ND-8.07) mg/kg濕重；可氯丹ND-<0.002 mg/kg乾重；毒殺芬<0.002 (ND-0.009) mg/kg乾重；總汞0.081 (0.011-0.726) mg/kg乾重；DMP及DEP皆為<0.05 mg/kg乾重；DBP，0.053 (ND-0.411) mg/kg乾重；BBP，<0.05 (ND-0.257) mg/kg乾重；DEHP，1.03 (ND-17.7) mg/kg乾重；DNOP，ND-<0.05 mg/kg乾重；TBT，ND-<0.053 mg/kg乾重；DBT，<0.038 (ND-0.133) mg/kg乾重；MBT，<0.053 (ND-0.379) mg/kg乾重；MPhT，<0.060 (ND-0.199) mg/kg乾重；DPhT及TPhT皆為ND；壬基酚，350 (1.98-7,380) ug/kg乾重；雙酚A，11.4 (ND-144) ug/kg乾重；PBDEs總量67,201 (157-954,547) ng/kg乾重。魚體樣本中可氯丹<0.001 (ND-0.009) mg/kg濕重；毒殺芬0.002 (ND-0.012) mg/kg濕重；總汞0.043 (0.018-0.111) mg/kg濕重；DMP及DEP皆為<0.025 mg/kg濕重；DBP，0.057 (<0.025-0.502) mg/kg濕重；BBP，<0.025 (<0.025-0.066) mg/kg濕重；DEHP，0.084 (<0.025-0.607) mg/kg濕重；DNOP，ND-<0.025 mg/kg濕重；TBT，ND-<0.013 mg/kg濕重；DBT，<0.010 (ND-0.051) mg/kg濕重；MBT，<0.013 (ND-0.020) mg/kg濕重；MPhT，<0.015 (ND-0.039) mg/kg濕重；DPhT，<0.010 (ND-0.050) mg/kg濕重；TPhT，0.027 (ND-0.236) mg/kg濕重；壬基酚，85.4 (3.15-687) ug/kg濕重；雙酚A，3.46 (ND-28.8) ug/kg濕重；氯苯及鄰-二氯苯皆為ND-<0.001 mg/kg濕重；PBDEs總量1,307 (132-4,967) ng/kg濕重。完成歷年毒性化學物質環境流布調查成果分析，並提具毒性化學物質因應管制措施建議，以及完成成果手冊101年版編印。

This project was to (1) determine concentrations of 28 toxic substances in water, sediments and fish of 10 rivers in Taiwan; (2) apply the investigation results for policy-making of toxic substance management; and (3) update the database of environmental distribution of toxic substances. There were 60 water and 60 sediment and 30 fish samples collected this year. In water samples, the mean concentrations and concentration ranges of analyzed toxic substances were ND-0.00367 mg/L for formaldehyde, ND for carbon tetrachloride, chlorobenzene and 1,2-dichlorobenzene, ND-<0.001 mg/L for 1,2-dichloroethylene and chloroform, respectively. In sediment samples, the mean concentrations and concentration ranges of analyzed toxic substances were <0.001 (ND-0.00964) mg/kg ww for chloroform, ND for 1,2-dichlorobenzene and 1,2-dichloroethylene, ND-<0.001 mg/kg ww for chlorobenzene, 0.397 (ND-8.07) mg/kg ww for As3+, ND-<0.002 mg/kg dw for chlordane, <0.002 (ND-0.009) mg/kg dw for toxaphene, 0.081 (0.011-0.726) mg/kg dw for total mercury, <0.05 mg/kg dw for DMP and DEP, 0.053 (ND-0.411) mg/kg dw for DBP, <0.05 (ND-0.257) mg/kg dw for BBP, 1.03 (ND-17.7) mg/kg dw for DEHP, ND-<0.05 mg/kg dw for DNOP, ND-<0.053 mg/kg dw for TBT, <0.038 (ND-0.133) mg/kg dw for DBT, <0.053 (ND-0.379) mg/kg dw for MBT, <0.060 (ND-0.199) mg/kg dw for MPhT, ND for DPhT and TPhT, 350 (1.98-7,380) ug/kg dw for NP, 11.4 (ND-144) ug/kg dw for BPA, and 67,201 (157-954,547) ng/kg dw for total PBDEs. For fish samples, the mean concentrations and concentration ranges of analyzed toxic substances were <0.001 (ND-0.009) mg/kg ww for chlordane, 0.002 (ND-0.012) mg/kg ww for toxaphene, 0.043 (0.018-0.111) mg/kg ww for total mercury, <0.025 mg/kg ww for DMP and DEP, 0.057 (<0.025-0.502) mg/kg ww for DBP, <0.025 (<0.025-0.066) mg/kg ww for BBP, 0.084 (<0.025-0.607) mg/kg ww for DEHP, ND-<0.025 mg/kg ww for DNOP, ND-<0.013 mg/kg ww for TBT, <0.010 (ND-0.051) mg/kg ww for DBT, <0.013 (ND-0.020) mg/kg ww for MBT, <0.015 (ND-0.039) mg/kg ww for MPhT, <0.010 (ND-0.050) mg/kg ww for DPhT, 0.027 (ND-0.236) mg/kg ww for TPhT, 85.4 (3.15-687) ug/kg ww for NP, 3.46 (ND-28.8) ug/kg ww for BPA, ND-<0.001 mg/kg ww for chlorobenzene and 1,2-dichlorobenzene and 1,307 (132-4,967) ng/kg ww for total PBDEs. The database searching system for concentrations of regulated toxic substances also has been updated with the investigation results this year.
