近年来,饮用水中某些化学物质的致突变性研究,国外已有报道;但饮水净化消毒剂本身是否有致突变性尚缺乏报道。经实验证明饮水中的一些化学致癌物如:苯并芘,一溴二氯甲烷等;虽然含量低,但累积后可引起细胞DNA损伤和基因突变,从而导致癌肿和遗传性缺陷等病变,由此表明致癌物亦可能就是致突变物。所以研究饮水净化 In recent years, some chemicals in drinking water mutagenicity studies have been reported abroad; but drinking water purification disinfectant itself mutagenicity is still lack of coverage. Experiments show that some of the chemical carcinogens in drinking water such as: benzopyrene, bromine dichloromethane, etc .; although the content is low, but after accumulation can cause cell DNA damage and gene mutations, leading to cancer and genetic defects and other diseases, This shows that carcinogens may also be mutagenic. So study drinking water purification
