天然水源普遍含有氯化物,一般饮用水中氯化物含量在2～100毫克/升之间,当水中氯化物>500毫克/升时,可出现咸味,所以一般饮水卫生标准为200～250毫克/升;在某些困难地区为400毫克/升;军队特殊情况下,最大容许浓度为600毫克/升,一个地区内,水源中氯化物含量是比较恒定的,如出现突然升高,可能是水源受污染。氯化物的检测方法很多,国内外推广使用的简易法是检测管法。中国预防医学科学院卫生研究所研制
Natural sources of water generally contain chloride, chloride content in general drinking water between 2 to 100 mg / l, when the chloride> 500 mg / l, salty taste may appear, so the general drinking water sanitation standards for 200 to 250 mg / L; 400 mg / L in some difficult areas; and 600 mg / L in special cases of the military. Chloride content in water sources in a region is relatively constant. Sudden increase may be Water pollution. There are many detection methods of chloride. The simple method of popularization and use at home and abroad is to detect the tube method. Chinese Academy of Preventive Medicine Research Institute of Health
