对３个铝厂电解车间空气氟浓度及其对工人健康影响进行了１５年动态观察研究。结果表明，３个铝厂１９７９年车间空气氟明显超高，且以甲、乙厂为明显；１９８９年各厂车间空气氟均明显降低，但１９９４年又有所回升，与防护措施有密切的关系。１９８９年工人尿氟明显低于１９７９年，但１９９４年又有明显升高，三厂间比较，丙厂好于甲、乙两厂，说明尿氟的改变与空气氟浓度密切相关，并与氟暴露呈明显剂量─—反应关系。
The air fluoride concentration in three aluminum plant electrolysis workshops and their effects on workers’ health were observed and studied for 15 years. The results showed that in the three aluminum mills, the air fluorine in the workshop was obviously higher than that in 1979 and that A and B plants were obvious. In the workshop of 1989, the fluorine in the air of the factories decreased obviously, but recovered again in 1994, which was close to the protective measures relationship. In 1989, the urinary fluoride of workers was significantly lower than that of 1979, but in 1994 there was a marked increase. Comparing the three plants, plant A was better than that of plants A and B. It showed that the change of urinary fluoride was closely related to the fluoride concentration in air and was associated with fluorine Exposure showed a clear dose-response relationship.
