C hlorine is an effective and reliable disinfectant whose use in the treatment of drinking water has ensured water of high microbiological quality. Although the benefits of chlorination are beyond doubt, the fact that chlorine reacts with many of the organic substances in raw waters forming some substances of potential risk to health has led to concern and has stimulated a series of investigations. These investigations have used a variety of approaches and techniques, including advanced organic analysis, epidemiology, and toxicology. The paper reviews this research and discusses some of the factors affecting the risks associated with drinking chlorinated water. 相似文献
