台灣南部地區石化廢水之致突變性研究

Mutagenicity of Wastewater Emitted by the Petrochemical Industry in Southern Taiwan

摘要


本研究以國內19家石化工廠和2家綜合污水處理廠之廢水爲對象,取得樣品21個,利用XAD-2樹脂抽取廢水樣品中之有機物質,再以丙酮洗下樹脂上吸附之有機物質,經濃縮之後進行沙門氏菌/微粒體系統(Salmonella/microsome system)之效突變性試驗。 研究結果發現有11個水樣(52.4%)呈現陽性的致突變性反應,而在沙門氏菌TA98菌種且有大白鼠肝臟微粒體酵素混合液下有較多的廢水出現陽性反應,結果亦顯示此21家工廠中有三家其廢水有較高的致突變性。

Twenty-one wastewater samples were collected from 19 petrochemical plants and two united wastewater treatment plants located in southern Taiwan during 1991. Water samples were passed through an XAD-2 resin column and the resin was then eluted by acetone. The mutagenicity of the wastewater was determined by the Ames Salmonella/microsome test. A total of 52.4%of the wastewater samples in the survey were found to exhibit mutagenic activity in Salmonella typhimurium TA98 and TA 100 in the presence and absence of S9 mixture. Three samples among the 21 samples, had very high levels of mutagenicity. The measurement and identification of mutagenic pollutants in wastewater need further investigation.
