本研究应用Ａｍｅｓ致突变试验对武汉东湖水分别经氯、二氧化氯和臭氧消毒处理后的致突变活性进行了检测与比较。结果表明：东湖水以及臭氧消毒处理水样未呈现致突变性,氯与二氧化氯处理的水样致突变性检测结果为阳性,这３种消毒剂处理的各水样致突变比活性强度顺序由强至弱依次为氯〉二氧化氯〉臭氧;同时对东湖水用高锰酸钾预处理,以降低氯化消毒饮水致突变活性的效果也进行了比较,结果发现用高锰酸钾预处理东湖水,可降低氯化
In this study, the mutagenicity was detected andcompared after treatment of the Wuhan EastLake water with chlorine, chlorine dioxide ofozone. The concentrates of untreated and ozonetreated water at all sample collection dates we-renonmutagenic in the Ames test. Both chlorineand chlorine dioxide treatment of the water resulted in increases of TA98 mutagenicity. Comparative analysis of these treated waters for mutagenicity showed a consistent pattern of mutagenicpotency, with decreasing activity in the Order:chlorine > chlorine dioxide > ozone. The studyalso found that pretre.Ptment of water with potas.slum permanganate prior to chlorination Was ef.fective in reducing the level of rnutagenicity whichformed durihg chlorination.,
