摘要
为了探讨燃煤污染是否是安徽淮北地区氟中毒的主要氟源 ,选择芦岭镇作为调查点 ,测定了该地区饮水、粮食、蔬菜、室内外空气等样品中氟含量。经计算 ,总摄氟量为4.77mg/人·日 ,其中饮水占 82 .18% ,食物占 17.4% ,由呼吸道摄入的氟量仅占 0 .42 %。由呼吸道摄入的氟量不到大气卫生标准允许限量的四分之一 ,即燃煤氟污染对氟中毒影响很小 ,饮水摄入的氟量是氟中毒的主要原因。提示安徽淮北地区不存在燃煤污染型地方性氟中毒。
In order to investigate whether the fluorosis pollution caused by burning coal was the main source of endemic fluorosis in north of Huai River, Anhui, Luling Town located in the area was investigated. We determined the fluorine content in the drinking water, grain, vegetables, indoor and outdoor air, and etc.. By calculating, the total intake amount of fluorine (F) was 4.77mg/person/day. The intake from drinking water and food accounted for 82.18%, 17.40% of the total intake value respectively, that from air was only 0.42%. The fluoride intake from air was less than a fourth of the limit amount of atmospheric hygienic standard of fluoride, that is, the effect of fluoride pollution caused by burning coal on endemic fluorosis was little. The fluoride from drinking water was main source of endemic fluorosis in Luling Town. The results showed that there was not coal-pollution-burned endemic fluorosis in north of Huai River, Anhui.
