Abstract:
Objectives To explore the effects of control measures and dynamic prevalence of drinking water endemic fluorosis in China, to provide basis and technique support for endemic fluorosis control in China. Methods The survey was carried out according to the national surveillance Scheme of Endemic Fuorosis. The fulfillment of control measures and the quality of water improving projects were surveyed. Household water sample and urine of children aged 8-12 years were collected and fluoride content was detected by iron selective electrode method. Check the teeth of children aged 8-12 years. Dental fluorosis was diagnosed by Dean's method. Results projects were build in 84 endemic villages in 2006, and the average water improving rate came to 73.98% fluoride contents of half the surveyed spots were over the standard, mainly between 1.0-2.0 mg/L, and the urine controlled just in only few spots and it was in moderate or severe status in some endemic areas for many years. Conclusions Little progress of control measures in drinking water endemic fluorosis counties surveyed has been made in these two years. Projects of running out of status and over standard of water fluorosis are frequently seen. Dental fluorosis in many spots is not controlled.
