本文对上海某冶炼厂80名钒作业工人进行了肺功能检查,前后共二次,间隔9个月。结果接触钒组与对照组相比,MMEF的下降两次均有统计学意义;前后两次肺功能比较无明显差异;工人当天上班前后的肺功能观察结果表明,钒化合物无类似二异氰酸甲苯对肺功能有即时影响的作用。
In this paper, 80 vanadium workers in a smelter in Shanghai carried out pulmonary function tests, two times in total, with an interval of 9 months. Results Compared with the control group, the vanadium exposure group showed a significant decrease in MMEF twice and no significant difference in lung function between the two groups before and after exposure. The observation of pulmonary function before and after working day showed that the vanadium compound had no similar effects Toluene has a immediate effect on lung function.
