摘　　要：目的:为了提高实验室检测结果的准确性与可比性,以及检验机构的整体能力,识别实验室间存在的差异。方法:采用国际通用的稳健统计用"Z比分数"的统计方法对水中砷、汞的检测结果进行分析。结果:此次质控样品共发放至全省各相关的检验机构中心共189家实验室,其中砷检测结果满意的有137家,满意率为78.7%;汞检测结果满意的有100家,满意率为76.9%。结论:全省检验机构的汞、砷总体检测能力较高,部分实验室技术质量水平有待提高。Objective ：To enhance the accuracy, reliability and comparability of laboratory testing results, and to improve the general testing capability of laboratories as well as identify the differences among laboratories. Methods：The testing results of arsenic and mercury in water were analyzed by using ＂Z - score＂ statistical method which is for international purpose. Results ： The quality - control samples were distributed to 189 related laboratories in Zhejiang province. 137 laboratories delivered satisfying tes- ting results of arsenic, which accounted for 78.7% of the total. And 100 laboratories delivered satisfying testing results of mercury, which accounted for 76. 9%. Conclusion： The general testing capability of arsenic and mercury in laboratories of Zhejiang province is quite good. However, several testing laboratories still have much to do to improve their technical quality.
