运城市家畜地方性氟病的调查报告

运城市家畜地方性氟病,主要分布在水氟含量在1.6毫克/升以上的16个乡189个村。病区牧草申氟含量超过国家规定标准(40毫克/公斤)4—8倍。病牛骨氟含量为2312.25ppm,超过正常牛骨氟值近两倍。尿氟超过正常值的1—4倍。调查结果表明,水氟含量越高,尿氟含量亦高,家畜年令越大,尿氟含量越高。运城市地方性氟病的发生主要由于家畜长期饮用含氟量高的水草后,使畜体内氟逐渐蓄积而导致家畜慢性氟中毒。

A STUDY OF ANIMAL LOCAL FRUOROSIS IN YUNCHENG AREA

This diseases was mainly distributed in 16 native places and 189 villages where there were 1. 6mg/L fluovine in the water. The fluorine level in diseases area was 4—8 times higher than that national level (40mg/kg). The disease—cow's bone—fluorine level was 2312. 25 ppm, to surpass about twice of normal cow's. The urine—fluorine level in patient was 1—4 times higher than normal's. The result showed that the more water—fluorine level, the more urine—fluorine level. The more animal age. the more urine—fluorine level. the cow body's fluorine saved up was mainly caused by drinking water and eating grass in Yuncheng city.
