对50名甲酸生产工人及73名非甲酸接触者测定尿中甲酸的含量,同时对甲酸车间的劳动卫生环境进行了空测。结果表明劳动环境空气中甲酸浓度较高,观察组尿甲酸均值明显高于对照组,P<0.01。阳性率的 RR 为9.6,RR 的 x~2检验 P<0.001。不同岗位的空气浓
50 formic acid production workers and 73 non-formic acid contact determination of urinary formic acid content, at the same time Formic acid workshop labor and health environment was measured. The results showed that the concentration of formic acid in working environment air was higher, and the average urinary formic acid in observation group was significantly higher than that in control group (P <0.01). The positive rate of RR was 9.6, RR of x ~ 2 test P <0.001. Different positions of the air thick
