地方性氟中毒(又称地方性氟病),是一种因长年饮用含氟量高的水引起的一种地方病(个别地方也有因食物中含氟量高而引起的),以斑釉齿(又称氟斑牙)、腰腿疼痛、运动功能障碍和骨骼变形等为其特征。这种病划地为域,发病区和非病区境界分明,对群众健康和四化建设影响很大。氟是机体生长不可缺少的微量元素,通常从饮水和食物中摄取,每日约需3.0～4.5毫克,如缺乏,则龋齿的发病率增加;但如过多,则会造成蓄积中毒。为防止氟的蓄积中毒,预防龋齿,我国规定饮水含氟的适宜浓度为0.5～1.0毫克/升,不得超过1.0毫克/升。
Endemic fluorosis (also known as endemic fluorosis) is a endemic disease caused by years of drinking water containing high levels of fluoride (due to the high fluoride content in food in some places) Tooth (also known as dental fluorosis), waist and leg pain, motor dysfunction and skeletal deformation as its characteristics. The disease plan for the domain, disease-free areas and non-ward boundaries clear, on the health of the masses and the four buildings a great impact. Fluorine is an indispensable organism trace elements, usually from drinking water and food intake, about 3.0 ~ 4.5 mg daily, such as lack of, the incidence of dental caries increased; but if too much, it will cause accumulation of poisoning. To prevent the accumulation of fluoride poisoning, prevention of dental caries, China’s drinking water fluoride concentration of 0.5 ~ 1.0 mg / l, shall not exceed 1.0 mg / l.
