摘要
目的对成都市2012年-2013年生活饮用水中19项元素指标进行检测分析,以了解水质状况,确保饮用水安全。方法根据GB 5749—2006《生活饮用水卫生标准》,采用电感耦合等离子体发射光谱(ICP-AES)和电感耦合等离子体质谱(ICP-MS)方法,对2012年-2013年成都市疾病预防控制中心辖区内生活饮用水中的19项元素指标进行检测,并对检验结果进行评价。结果 2012年-2013年共检测成都市水源水、出厂水、二次供水等各类生活饮用水共计1 741件,总合格率为97.30%,其中铁、锰、铝等元素检出较多。结论成都市城市生活饮用水中检测的元素指标总体情况较好,但仍应加强自备供水及二次供水的监管,防止生活饮用水中某些元素的含量出现超标现象。
Objective The index of 19 elements in drinking water in Chengdu during 2012- 2013 were detected and analyzed in order to understand the water quality conditions to ensure safe drinking water. Methods According to GB 5749—2006Drinking Water Health Standards,using inductively coupled plasma atomic emission spectrometry（ ICP- AES） and inductively coupled plasma mass spectrometry（ ICP- MS） method,19 element indicators of drinking water in the center of the Chengdu disease prevention and control during 2012- 2013 year were detected,and the test results were evaluated. Results A total of1 741 pieces of source water,finished water,secondary supplying water and other types of drinking water of Chengdu during2012- 2013 were detected,the total pass rate was 97. 30%,and and among them iron,manganese,aluminum and other elements were detected out more. Conclusion The overall situation of metal index in Chengdu drinking water is better,but we should strengthen the regulation of secondary water supply and prevent the content of elements in drinking water exceeding phenomenon.
