地方性氟中毒是严重危害人体健康的地方病。1964年,发现该病在我省有较大面积的流行,并查清了当地居民饮用的浅井水氟含量过高是造成该病流行的原因。同年,试用打深井改饮低氟水的方法来防制氟中毒。为了解改水后的防制效果,以及改水病区流行病学特点与概貌,作者在不同改水时间采用多项指标对改水后的居民健康状况进行了追踪观察。1 材料与方法1.1 时间与地点 在改水初的1964年及改水后的1974、1980、1985、1990和1995年分别对乾安、农安、大安三县的尔字、令字、刘家围子、小能、位字、小松、东宾、大宾、东鞠、东南竞屯的居民及氟骨症患者分别进行了调查。同时在上述地区选择条件类似的非病区小帅屯及未改水病区腰陶和逯家屯作为对照观察点做了与改水病区内容相同的对照调查。
Local fluorosis is a serious endemic disease to human health. In 1964, the disease was found to have a large area of endemicity in our province and it was found out that the high fluoride content in shallow wells drunk by local residents was the reason for the epidemic. In the same year, try to fight deep well to drink low fluoride water to prevent fluorosis. In order to understand the control effect after water diversion and the epidemiological features and profiles of water-changing areas, the author used several indicators to track the health status of residents after the water diversion. 1 Materials and methods 1.1 Time and place In 1964 and the water diversion in 1974, 1980,1985,1990 and 1995, respectively, after the dry water, Nong’an, Daan three counties word, the word, Liu We Wai , Small energy, the word, Komatsu, East Bin, Dabin, East Ju, southeastern Jing Tun residents and patients with skeletal fluorosis were investigated. At the same time, we chose the same non-ward Xiaoyuantun and non-watered-area loess pottery and Qijiantun as the control observation points in the above areas to make the same control survey as the water-wasting area.
