Methods Two villages named Xiaolongdong and Qinggangling were chosen as the surveillance spots for observing situation change for five years according to the requirements and methods of the national surveillance plan.Results (1)The fluorin level in the air has been controlled under the national standard level for several years after the stove reform;(2)The level of fluorin in corn which is the main food of the local people has been reduced;(3)The level of fluorin in the urine of children has been decreased under 1.0 mg/L;(4)The positive rate for dental fluorosis of children has been reduced to the controlled level of the epidemic area . Conclusions Stove reform is the main effective measure for reduce fluorin to prevent endemic fluorosis resulted from the pollution of coal burning, and the prevalence of fluorosis in the area has been gradually controlled with the increase of the rate for stove reform and the time is lasted.
