对饮水中有机物的关注,由来已久。1956年Middleton等报道了作为许多城市饮用水源的俄亥俄河水中有机物的含量。1962年制订了饮水中碳氯仿提取物(CCE)限值200μg/L。据1974年报道,饮水加氯消毒使水中某些卤代有机物浓度增高,形成数量最多的是三氯甲烷即氯仿。七十年代美国调查80个给水系统,发现氯化后水中普遍存在氯仿,在5个城市的饮水中鉴定出72种化合物。与此同时,美国国立癌症研究所的实验指出,氯仿使实验动物致癌。1976年Page等在探讨路易斯安那州饮水与癌症死亡率的关系肘,在新奥尔良饮水中鉴定出86种有机化合物。
The concern for organic matter in drinking water has been around for a long time. In 1956 Middleton et al. Reported on the organic matter content of the Ohio River as a source of drinking water for many cities. In 1962, the limit of CCE in drinking water was 200μg / L. According to the 1974 report, chlorinated water disinfection of drinking water increased the concentration of some halogenated organic compounds, the formation of the largest number of chloroform or chloroform. In the 1970s, the United States surveyed 80 water supply systems and found that chloroform was generally found in chlorinated water and that 72 compounds were identified in drinking water in five cities. In the meantime, experiments by the National Cancer Institute have pointed out that chloroform causes cancer in laboratory animals. In 1976, Page et al explored the relationship between drinking water and cancer mortality in Louisiana and identified 86 organic compounds in New Orleans drinking water.
