迄今不少国家仍用四乙基铅(Et_4Pb)作为汽油的抗爆剂,但有关职业接触Et_4Pb的评价指标问题尚未解决。有些资料曾报道在急性Et_4Pb中毒时,尿中排泄的代谢物主要是二乙基铅(Et_2Pb)。Chiesura曾提出Et_2Pb可以作为职业接触Et_4Pb的一项特异指标,但未能确认。为此作者对某汽油公司的有关作业场所空气中Et_4Pb浓度进行了监测,并重点测定了贮 To date, tetraethyl lead (Et_4Pb) is still used as an antiknock of gasoline in many countries. However, the issue of occupational exposure to Et_4Pb has not been solved yet. Some data have previously reported that the urinary excretion of metabolites is primarily diethyl lead (Et 2 Pb) in acute Et 4 Po poisoning. Chiesura has proposed Et_2Pb as a specific indicator of occupational exposure to Et_4Pb but failed to confirm. To this end the author of a gasoline company on the workplace air Et_4Pb concentrations were monitored and focused on the determination of storage
