In order to find out the cause of endemic fluorosis in our county, we investigated the causes of endemic fluorosis in Luoping County in December 1990 (1800m above sea level, with an average annual temperature of 15 ℃ and a sunshine duration of 1677.4h) in drinking water, food, soil , Raw coal laboratory fluorine content control analysis. The results see the schedule.
