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 To detect and analyze 19 elements of drinking water in Chengdu from 2012 to 2013 to understand the water quality and ensure the safety of drinking water. Methods According to GB 5749-2006 Standard for Drinking Water Quality, the author used inductively coupled plasma-atomic emission spectrometry (ICP-AES) and inductively coupled plasma mass spectrometry (ICP-MS) The central area of drinking water in the 19 elements of the index test, and the test results were evaluated. Results A total of 1 741 drinking water samples were collected from drinking water, factory water and secondary water supply in Chengdu from 2012 to 2013, with a total pass rate of 97.30%. Among them, more elements such as iron, manganese and aluminum were detected. Conclusion The urban drinking water in urban areas has a better overall indicator of the quality of the detected elements. However, the monitoring of self-provided water supply and secondary water supply should be strengthened so as to prevent excessive occurrence of some elements in domestic drinking water.
