本世纪70年代以来,美国给水工作协会杂志,连续的刊登自来水经氯化消毒,因水中有机物与氯反应,生成卤化有机物,有些有致癌性,因而引起了人们的重视与关注。现将部分文献资料介绍如下: (一)氯化消毒的自来水中检出了卤化有机物在过去10年里,由于分析化学的进展,已能检出水中大量的有机物,并可作微量测定。美国环境保护局1974年发表的报告指出,1972～1974年,在美国最大的河流密西西比河口新奥尔良市自来水中,检出了66种有机物,其浓度为0.01微克/升～5.0微克/升。之后,又检出了一些有机化合物总数已超过100种。这些有机物,主要来自工业废水的污染。环境保护基金会报道,饮用新奥尔良市自来
Since the 1970s, the American Water Supply Association magazine has continuously published chlorinated disinfection of tap water. Because organic matter reacts with chlorine to form halogenated organic compounds, some of them are carcinogenic, which has caused people’s attention and concern. Now part of the literature and information is introduced as follows: (I) Halogenated organic matter detected in chlorinated tap water In the past 10 years, due to the progress of analytical chemistry, a large amount of organic matter in water has been detected, and micro determinations can be made. According to a report issued by the U.S. Environmental Protection Agency in 1974, from 1972 to 1974, 66 organic substances were detected in tap water in New Orleans, the largest river in the Mississippi River in the United States. The concentrations ranged from 0.01 μg/L to 5.0 μg/L. Later, the total number of organic compounds detected has exceeded 100. These organics are mainly from the pollution of industrial wastewater.
