Abstract

Using male rats, the availability of fluoride from five by products of the aluminium smelting industry was tested. This was done by considering the balance between fluoride administered in controlled diets and the total fluoride content of waste products eliminated over an experimental period of 1 week. 2. Results indicated that yields of available fluoride expressed as percentage weight of original material were cryolite (Na3ALF6), 45.9%; sodium fluoride (NaF), 41.7%; aluminium fluoride (AFL3.H20), 9.1%; mist eliminator grid solids (with CaF2), 9.4%; reclaimed alumina with adsorbed F, 0.27%. 3. Of the various tissues analysed for fluoride content, only the kidney and femur showed any significant correlation with the amounts of fluoride absorbed or retained.

摘要

使用雄性大鼠，对铝冶炼行业的五种副产品中的氟化物可用性进行了测试。通过考虑在对照饮食中施用的氟化物与在1周的实验期内消除的废物产品的总氟含量之间的平衡来完成此操作。2. 结果表明，以原始材料重量百分比表示的可用氟化物产量为：冰晶石（Na3ALF6），45.9%；氟化钠（NaF），41.7%；氟化铝（AFL3.H20），9.1%；除雾器格栅固体（含CaF2），9.4%；吸附氟的再生氧化铝，0.27%。3. 在分析氟含量的各种组织中，只有肾脏和股骨与吸收或保留的氟量显示出任何显著相关性。
