| 摘 要： | 酸浸／电极法是当前广泛采用的测定粮食中氟含量的国家标准方法，该方法仅对样品进行一次酸液浸泡测定。研究表明对燃煤型地氟病区的主要携氟介质玉米一次酸浸即可提取全部酸溶性氟，但辣椒却需要经过多次酸浸提取；玉米和辣椒的酸不溶态氟含量基本为一定值，这两点在制订粮食的含氟量及人体的摄氟量卫生标准时宜作适当考虑。

| Abstract: | The method of acid lixivium / ISE is widely used to determine fluorine in food,but the food is extracted by acid lixivium only by once in the state standard method. Corn is the staple food,and chili isthe favorite vegetable in the coal - burning endemic fluorosis areas. Fluorine in corn can be totally extracted by acid lixivium by once. Due to its abundant lipid, fluorine in chili can be totally extracted by several times. The fluorine content in the residue of acid lixivium is a constant. These factors should be taken into account when the limits is laid down for fluoride exposure and fluorine levels in foodstuff. |
