ABSTRACT
Objective To find out the distribution and status of drinking-water-borne fluorosis in Qinghai,and to provide basic data for prevention and control of the disease.Methods According to the "Action Plan of Endemic Fluorosis and Arsenic Poisoning in Qinghai (2016-2020)",10 counties were selected to carry out the epidemiological study in 2016.The operation of the improvment project was investigated.The fluoride content of water was determined with fluoride ion-selective electrode,and dental fluorosis of 8-12 years old children was diagnosed by the Deans method.Results A total of 97 villages have been investigated,and all water was improved.The range of water fluoride was 0.20-2.13 mg/L.Normal operation rate of water-improving project was 83.33% (50/60).The pass rate of water fluorine content was 96.67% (58/60).The prevalence rate of dental fluorosis of the children was 18.70% (774/4 140),and it was significantly lower than national standards (30%).Conclusions Water has been improved in all of the fluorosis villages.Most of the water-improving engineering projects to control drinking-water fluorosis has played a positive role,and drinking-water-borne fluorosis is under control.
