2010年饮用水中硫酸盐和铜质控结果分析

Analysis of inner-laboratory comparison results of sulfate and copper in drinking water in 2010

目的:为了更好的提高全省疾控中心实验室在饮用水方面的检测水平。方法:依照《生活饮用水标准检验方法》(GB/T5750.5/6-2006)对应方法对合成水样中硫酸盐和铜进行质控考核。用Z比分数统计评价检测结果,分为满意、可疑和不满意3种。结果:此次对全省18个地市和55个县市疾控中心共73个实验室进行水质检验质量控制考核,硫酸盐测定结果满意的57家,占78.1%;结果可疑的8家,占11.0%;结果不满意的8家,占11.0%。铜测定结果满意的64家,占87.7%;结果可疑的8家,占11.0%。结果不满意的1家,占1.3%。结论:全省各级疾病预防控制中心硫酸盐、铜总体检测能力较高,少数实验室检测能力有待提高。

Objective：In order to well enhance the accuracy of laboratory detection result in drinking water.Methods： The sample was detected according to ＂Standard examination methods for drinking water＂（GB/T5750.5/6-2006） and the detection results were analyzed by ＂Z-score＂.Results： Detection results were provided by 73 laboratories of city and county centers for disease control and prevention.The detection results of sulfate were satisfactory in 57 laboratories（78.1%）,suspicious in 8 laboratories（11.0%） and dissatisfactory in 8 laboratories（11.0%）;while the detection results of copper were satisfactory in 64 laboratories（87.7%）,suspicious in 8 laboratories（11.0%） and dissatisfactory in1 laboratory（1.3%）.Conclusion： The general testing capability on sulfate and copper is relatively high.However,there is still much room for improvement on testing quality level in several laboratories.
