国内外流行病学调查提示,人类某些癌症死亡率和发病率与饮水质量存在一定相关性,至1981年,全世界饮水已鉴定出767种有机污染物。其中,确认为致癌物的20种,可疑致癌物26种,促癌物或助癌物18种,Ames试验致突变性物质48种。美国等国家对饮水诱变性也进行了大量的实验室研究,表明饮水存在致突变性物质。我国自七十年代后期开
Epidemiological studies at home and abroad suggest that some human cancer mortality and morbidity have a certain relationship with drinking water quality. By 1981, 767 kinds of organic pollutants were identified in drinking water worldwide. Of these, 20 were identified as carcinogens, 26 as suspected carcinogens, 18 as carcinogens or carcinogens, and 48 as mutagens by Ames. The United States and other countries on the mutagenicity of water also conducted a large number of laboratory studies, indicating that mutagenicity exists in drinking water. My country has been open since the late seventies
