摘要
目的了解贵州省饮用水检测实验室对氟化物的检测能力状况。方法2010年对全省9个市（州）和31个县级实验室进行氟化物检测能力考核，采用单一Z比分数法进行检测结果单项指标的评价．测定方法采用《生活饮用水卫生标准检验方法》（GBIT5750．5—2006）中氟离子选择电极或氟试剂分光光度法。结果氟化物测定结果反馈率为100％，实验室满意结果率为82．5％（33／40），可疑结果率为7．5％（3／40），不满意结果率为10．0％（4／40）。结论参加能力验证绝大多数实验室的检测能力状况符合要求，部分的实验室检测能力有待提高。
Objective To find out the situation of laboratory testing capacity of fluoride in drinking water in Guizhou Province. Method Assessment of fluoride detection capabilities in nine cities （states） and 31 county- level laboratories of the province in 2010 was carried out, the test results of individual indicators were evaluated using a single Z-score method, and the determination was based on the fluoride ion selective electrode method of ＂Drinking Water Saritary Standard Test Method＂ （GB/T 5750.5-2006） or fluorine reagent spectrophotometry. Results The feedback rate of fluoride measurement results was 100%, the satisfactory rate of laboratory results was 82.5% ,the suspicious rate of results was 7.5%（33/40）,and the unsatisfied rate was 10.0%（3/40）. Conclusion The fluoride detection capability of most laboratories that participated in the proficiency test has met the requirements, and 10 percent of the laboratory＇s capacity needs to be improved.
