摘要
通过对9个燃煤型氟病区儿童发样硒含量测定,病区儿童发硒水平普遍较高,个别地区如巫山县建坪乡发硒高达6.9813μg/g),其居民主食硒含量比其它地区玉米高5—40倍,可能与煤烟污染内外环境有关。使用这种高硒粮,推算每人平均每日硒摄入量达362.8μg。此外,燃煤可直接污染头发,也是造成氟病区儿童发硒高的另一个原因。
According to analysis of the hair So co(?)tents of the children in 9 sites of coat burning pattornendemic fluorosis areas,the hair Se contents in endemic areas were more than those in non-en-demic areas.Such as an average of the hair Se contents in Wushan was about 6.9813 mg/kg andSe contents of corn which are main grain crops for the resisdents of these areas were 5 to 40 timesthose in other areas.The cause may be environmental potution by coal ashes.An average of Seconsumed of everybody is estimated at 362.85μg in a day.In addition burning coal can polute derectly the hair of children by air.This is another causewhy the hair Se contents increased.
