萍乡地区空气污染型氟中毒的氟化物转移特点

The Fluoride Transference Characteristics of Air Pollution type Fluorosis in Pingxiang Region

为探讨萍乡地区空气污染型氟中毒的氟化物转移特点，对萍乡地区环境地质进行了调查，并对土壤及水中氟化物进行测定，结果显示该地区环境地质背景类似于半湿润富铁铝地球化学环境，中性和酸性土壤氟化物聚集区。由于该地区的地质特点形成氟化物富集的土壤，这正是当地居民拌煤和烧制砖瓦的主要原料。煤和土壤在燃烧过程中排出大量氟化物，污染空气、水和食物等，危害人群的健康，引起氟中毒。

For the aim of approaching the fluoride transfer characteristics of air pollution type fluorosis,the investigation of environmental geology and determination for fluoride in soil and water were carried out in Pingxiang Region,Jiangxi Province.The resutts showed the background of environmental geology for air pollution type fluorosis in the region is similar to semimoist,allite rich and ferroaugite rich geochemical environment,in which,the fluoride of neutal and acidic soil were accumulated.The high fluoride soil caused by geochemical environment in the region just was the main resourse of mixing coal and baking bricks or tiles among the residents,during the process of coal burning and soil baking,a large amount of fluoride was eliminated to pollute air,water and food,etc.that endanger human health,and lead to fluorosis.
