摘要
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 13 kinds of inorganic elements in 156 drinking water samples collected from 28 cities and counties in Jilin province 2013. Methods According to Standards for Drinking Water Quality（ GB/T 5750. 6 - 2006 ）, 13 kinds of elements were tested by inductively coupled plasma mass spectroometry including irun, manganese, cop- per, zinc, beryllium, nickel, molybdenum, silver, cadmium, antimony, barium, thallium and lead. Results Among the 13 kinds of inorganic elements, the qualified rates of iron manganese and copper were 94.9% , 92. 3% and 92. 3%, respectively. Qualified rates of the others were I00. 0%. Pass rate of the 13 kinds of inorganic elements from municipal water supply was 91.9% , self- built waterworks water supply was 69.8% , the secondary water supply was 94. 1%. Con- clusion The pass rate of the 13 kinds of inorganic elements from municipal water supply is obvious higher than from self - built waterworks water supply. It＇ s suggested to strengthen the supervision and management of the water supply form self - built waterworks
