摘要
丰、沛、铜重氟病区，禽、畜体内氟主要积聚在骨骼中（羊骨１０９６×１０－６～２００１．９×１０－６，鸡骨３３５×１０－６～３７８×１０－６）及生理功能强的内脏（肝、心、肾等）器官中，氟的含量３．３×１０－６～７．１７×１０－６，肌肉和蛋、奶品中氟的含量大多接近或低于氟的卫生标准，显然肉、蛋、奶食品不是该区地氟病的致病因子。研究表明，动物体内氟含量与环境水氟及叶菜和树叶（含水分高）中的氟含量呈明显的正相关。因而造成食草动物比以食粮食为主的家禽体内的氟含量明显偏高。说明水是氟的传播媒界，为该区地氟病的主要致病因子。
狥luoride accumulates mainly in bones (sheep bone 1096×10 -6 ～2001.9×10 -6 ,chicken bone 335×10 -6 ～378×10 -6 ) and internal organs (liver,heart and kidney of strong physiological function with 3.3×10 -6 ～7.17×10 -6 ) of domestic animals in heavy fluorosis region in Feng,Pei and Tongsan counties.Fluoride content in milk,egg and muscle is mostly close to or less than fluoride hygienic standard,showing obviously that these foods are not disease-causing factors of the fluorosis.The results also show that there is a positive relationship between fluoride content in the animal bodies and that in water environment and leave of vegetables and trees,so the fluoride content in the body of aniamal eating grass is higher obviously than that of domestic fowl eating grain.It is a clarified that water is a spreading medium of fluoride and main disease causing factor of the epidemic fluorosis in the region.
