【摘要】 <正> 在开展无机氟对工人危害的防治研究工作中,我们曾先后进行了715名正常工人的尿氟测定和氟作业工人尿氟排泄规律的探讨。本文拟对电解铝工人和磷肥(过磷酸钙)生产工人的尿氟含量与生产场所空气中氟化物浓度进行调查测定,并对尿氟含量与空气中氟化物浓度的关系进行初步探讨。更多还原

【Abstract】 The urine-fluovides (F) of 1450 workers exposed to fluoride were determined, the F contents are much higher than that of nonexposure group. The urine-fluoride may be used as an index to evaluate industrial exposure lerel of fluoride. 171 Samples of air were collected for determination of F. The relationship between fluoride contentes in air and urine is very close. A straight regression equation is described as Y (mg/m~3)=0.4198+0.2365X (mg/l).更多还原
