目的了解2013年吉林省28个市、县156份生活饮用水中13种无机元素的存在情况。方法根据《生活饮用水标准检验方法》(GB/T 5750.6-2006)中电感耦合等离子体质谱法进行检测,检测项目为铁、锰、铜、锌、铍、镍、钼、银、镉、锑、钡、铊、铅共13项指标。结果 2013年吉林省28个市、县156份生活饮用水中13种无机元素铁的合格率为94.9%,锰的合格率为92.3%,铜的合格率为99.4%,其他10种元素合格率均为100.0%。13种无机元素的合格率市政供水为91.9%,自建水厂供水为69.8%,二次供水合格率最高为94.1%。结论所监测的13种无机元素市政供水合格率明显高于自建水厂供水的合格率,自建水厂应当加强管理和监管。
Objective To understand the presence of 13 inorganic elements in 156 drinking water in 28 cities and counties in 2013 in Jilin Province. Methods According to the “Standard Test Method for Domestic Drinking Water” (GB / T 5750.6-2006), ICP-MS was used to detect iron, manganese, copper, zinc, beryllium, nickel, molybdenum, silver, cadmium and antimony , Barium, thallium, lead a total of 13 indicators. Results In 2013, drinking water quality of 156 drinking water in 28 cities and counties of Jilin Province was 94.9%, the pass rate of manganese was 92.3%, the pass rate of copper was 99.4%, and the pass rate of other 10 kinds of elements All 100.0%. The pass rate of 13 inorganic elements was 91.9% for municipal water supply, 69.8% for self-built water supply and 94.1% for secondary water supply. Conclusion The qualified rate of municipal water supply of the 13 inorganic elements monitored is obviously higher than the qualified rate of self-built water supply. Self-built waterworks should be strengthened management and supervision.
