Abstract:
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 countylevel 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.
