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 coal-burning pollution is the main fluoride source in fluorosis in Huaibei area of Anhui province, Luling town was selected as the investigation point to determine the fluoride content in drinking water, food, vegetables, indoor and outdoor air in the area. After calculation, the total amount of fluoride taken was 4.77mg / person · day, of which drinking water accounted for 82.18%, food accounted for 17.4%, fluoride intake by the respiratory tract accounted for only 0.42%. Fluorine intake by the respiratory tract less than one quarter of the allowable limit of the standard of the health of the atmosphere, that is, fluorine pollution from coal combustion has little effect on fluorine poisoning, and fluorine intake from drinking water is the main reason for fluorosis. Prompt Anhui Huaibei area does not exist coal-fired pollution endemic fluorosis.
