用叙利亚地鼠胚胎（syrianhamesterembryo，SHE）细胞转化实验研究了G市自来水公司所属的4个水厂的水源水、自来水及2个新拟建的水源点水样有机提取物的细胞毒性和潜在的致癌性。结果：4个采样点的水源水及自来水可不同程度地诱导转化灶的形成，并有一定的细胞毒性；各点自来水的转化率与源水相比有增高的趋势；新拟建的2个水源取水点水样虽有一定的细胞毒性，但无致转化作用。结论：水源水经一般的氯化消毒处理。可增加水中的致突变致癌物质；细胞毒性与遗传毒性并不成平行关系。
Cytotoxicity and potential toxicity of water extract, tap water and two newly proposed water-point organic extracts from four water plants owned by G City Water Company were studied using Syrian hamesterembryo (SHE) cell transformation experiments. Carcinogenicity. Results: The water and tap water at 4 sampling points induced the formation of foci to varying degrees and had certain cytotoxicity. The conversion rate of tap water at each point was higher than that of the source water. The newly proposed 2 Although the water intake of water samples have some cytotoxicity, but no conversion. Conclusion: The source water is treated by general chlorination. Mutagenic carcinogens can increase the water; Cytotoxicity and genotoxicity is not parallel.
