本研究在2006年四個季節,針對台灣西部沿岸之四大漁市場販賣的食用魚類包括:白帶魚、赤鯮、金目鱸、午仔、黑鯛、高鼻海鰶、鰈魚、台灣鳳螺以及珠螺等,進行有機錫(包含:單丁機錫、二丁機錫、三丁機錫以及四丁機錫)之監測與調查,結果發現累積於魚體(肌肉及內臟)中之有機錫濃度分別爲:單丁機錫n.d.-949.2±49.1 ng/g、二丁機錫n.d.-56.2±7.9、三丁機錫n.d.-70.8±10.0 ng/g、四丁機錫n.d.-103.8±76.9 ng/g(濕重),由於二丁機錫與三丁機錫之毒性相似且較其他有機錫化合物高,因此在此研究中將二丁機錫與三丁機錫濃度相加之後再進行毒性之評估,發現其最高濃度也遠低於根據美國環保署訂定之每人每天可忍受之三丁機錫攝取量與台灣人每日平均魚類攝取量算出之有機錫平均殘留耐受濃度(tolerable average residue level; TARL)175.4 ng/g(濕重),所以台灣西部沿岸四大漁市之經濟性魚種之食用對人體健康並無危害。
Fishes commonly consumed in Taiwan were purchased from four fish markets at seasonal intervals in 2006 in order to monitor the butyltin residues, including monobutyltin (MBT), dibutyltin (DBT), tributyltin (TBT), and tetrabutyltin (TeBT), in fishes caught along the west coast of Taiwan. Concentration of MBT, DBT, TBT, and TeBT in the muscle or the internal organ of these fishes were in the range of n.d.-949.2±49.1, n.d.-56.2±7.9, n.d.-70.8±10.0, and n.d.-103.8±76.9 ng/g (wet weight), respectively. Owing to the toxicological similarity between DBT and TBT, total concentrations of DBT plus TBT in the muscle or the internal organ were taken as the standard for the residue level of butyltins and they were found lower than the tolerable average residue level (TARL) of 175.4 ng/g (wet weight). Therefore, butyltin levels in fish from Taiwanese markets are not a matter of concern for public health.
