随着工业的发展,世界范围内饮水水源污染越来越严重,上世纪50年代以前水源主要受病原微生物的污染,20世纪中叶水源受到重金属的污染,20年来,水的有机物污染日益严重,饮水危害健康十分严峻。我国的《生活饮用水标准》仍是上世纪80年代初讨论制定的,而近20年来出现的大量新的合成有机物是不可能纳入十几年前的水质标准的。目前国外饮用水标准,尤其是美国的饮用水标准每隔一年就要审查修订,以增加新的测试项目和指标。因此,本文介绍了时时更新的美国饮水条例,以期对我国饮用水标准的修订予以借鉴。
With the development of industry, the drinking water sources around the world are polluted more and more seriously. Before the 1950s, water was mainly polluted by pathogenic microorganisms. In the middle of the 20th century, the water was polluted by heavy metals. In the past 20 years, Harmful to health is very serious. China’s “drinking water standard” is still the discussion of the early 1980s developed, and the emergence of a large number of new synthetic organic substances in the past 20 years is not likely to be included more than a decade ago the water quality standards. At present, drinking water standards in foreign countries, especially the drinking water standards in the United States, should be reviewed and revised every other year to add new test items and indicators. Therefore, this article introduces the American Drinking Regulations updated from time to time, with a view to reference our revision of drinking water standards in our country.
