为了解我区地方性氟中毒在局部地区流行原因,我们于1985年8月开始在安顺县选点作人群氟中毒流行病学及环境氟调查,现将调查结果报告于后。一般情况安顺县位于贵州中部,终年气候温和,该调查点距县城13公里,周围无工业氟污染。经济条件尚可,主食为大米,粮食基本自给,燃料以烧煤为主(来源于本地),当地无烘烤 In order to understand the endemic fluorosis in our district in some areas, we started the epidemiology and environmental fluorosis survey of fluorosis in Anshun County in August 1985 and report the findings later. General Anshun is located in the central part of Guizhou, with a mild year-round climate. The survey point is 13 kilometers away from the county seat and there is no industrial fluorine pollution around it. Economic conditions are acceptable, the staple food is rice, the basic food self-sufficient fuel to coal-based (from local), local baking
