Objective To understand the fluorine content of human body in Nanzhuang Town and Xiaotang Town, Nanhai City as the basis for formulating the anti-caries plan and the baseline data for the evaluation of anti-caries project. Methods The blood of the crowd was collected in two towns and digested. The total fluoride content in whole blood was determined by fluoride ion selective electrode. Results The average total fluorine content of whole blood samples of Nanzhuang was (1.5 7 ± 0.43) mg / L. The average total fluorine content of whole blood samples was (1.2 1 ± 0.46) mg / L. The two groups of people in total blood fluoride levels compared by u test difference was significant. Conclusion Nanzhuang Nanzhuang Town and Xiaotang Town did not find any abnormalities in the total fluoride content of whole blood.
