Objective To investigate the running condition of defluoridation projects and fluoride concentration in drinking-water in Anyang City of Henan Province.Methods Cluster sampfing of Anyang,Hua, Neihuang,Tangyin Counties emdimic fluomsis poining of Anyang City was conducted places of different orientation, about 1/3 towns in the selected examination towns had their defluoridation project investigated.Results Among 472 pwjects investigated,427 were running normally,accounting for 90.47%(427/472),only 9.53%(45/472)of the projects were out of service.68.62%(293/427)of the pwjects had normal fluoride concentration in drinking water, 31.38%(134/427)of the projects failed to do 80.In Hua County,41.00%(41/100)of the projects were out of service. In Neihuang County.70.39%(107/152)of the projects had abnormally high fluoride concentration in drinking water. Conclusions Defluoriding projects are out of service and fluoride concentration in drinking water exceeds the standard in Hua,Neihuang Counties of Anyang City.We must analyse the cause of it seriously,work out measures, promote a healthy and sustainable development of defluondation projects
