Title: Investigation on fluoride content in well water and prevalent state of fluorosis in endemic fluorosis area of Yangyuan County Hebei Province
Abstract: Objective To understand the fluoride contents of well water and prevalent state of fluorosis in endemic fluorosis area of Yangyuan County in Hebei Province.Method Randomly selecting 2 villages as objects,including one endemic area named Nanwa and one non-endemic area named Dongbu.Detemination fluoride content in well water and,investigation of dental fluorosis prevalence rate and deformed skeletal fluorosis in these villages.Results The fluoride content in well water of Nanwa was obviously higher than that in Dongbao(P0.01),contents at the range of 2.20 to 2.91mg/L,which were higher than the limit of Sanitary Standard for Drinking Water Quality(2001).The urine fluoride and dental fluorosis rate of children in Nanwa were obviously higher than that in Dongbao(P0.01),the dental fluorosis rate was 81.4%.There were 26 deformed skeletal fluorosis patients in Nanwa.Conclusions The fluoride contents in well water of endemic fluorosis area were seriously higher than the sanitary standard and people in endemic area still had severe fluorosis.
