作者通过对5名从事汽油加四乙基铅,14名铁路油槽车和7名油船装油工人的研究,其工作场所四乙基铅8小时加权平均浓度分别为0.480,0.016和0.009mg/m~3,发现接触空气四乙基铅高、低浓度的工人其尿中都有Et_2pb~(+2),其排出量与空气中四乙基铅浓度间有显著的相关(r=0.70),说明Et_2b~(+2)可以为职业性接触四乙基铅的一种特异性的指标。接触不同空气四乙基铅浓度的工人的尿中Et_2pb~(+2)/总铅量间比率是不同的,从而推
The study of five workers engaged in petrol and tetraethyl lead, 14 rail tankers and seven oil tankers loaded the workplace with tetraethyl lead in the 8-hour weighted average concentrations of 0.480, 0.016 and 0.009 mg / m, respectively ~ 3, Et_2pb ~ (+2) was found in the urine of workers with low and high levels of exposure to tetraethyl lead. There was a significant correlation (r = 0.70) with Et 2 pb ~ (+2) Et_2b ~ (+2) can be a specific indicator of occupational exposure to tetraethyl lead. The ratio of Et_2pb ~ (+2) / total lead in urine of workers exposed to different concentrations of tetraethyl lead in air is different, thus pushing
