几位作者已报道了在过磷酸盐行业中的氟中毒。如 Derryberry 氏发现暴露于空气中含氟化物浓度平均3.38mg/m~3的一组工人中骨骼发生改变,尽管这种变化未发生在平均接触2.65mgF/m~3的工人中。接近 EI Gha-_w abi 氏报道了在埃及的一座过磷酸盐工厂的工人中有36%的工人在骨密度上显示了程
Several authors have reported fluorosis in the superphosphate industry. For example, Derryberry found that skeletal changes occurred in a group of workers exposed to an average fluoride concentration of 3.38 mg / m3 in the air, although this change did not occur in workers exposed to an average of 2.65 mg F / m3. Close to EI Gha-ab abi reported that 36% of workers in a phosphate plant in Egypt showed a significant difference in bone mineral density
