摘要
目的 对某蓄电池厂铅作业工人的尿铅、血红蛋白（Hb）和血锌原卟啉（ZPP）进行生物监测分析.方法 检测电池厂工作场所空气中铅浓度,对接触铅作业的工人进行职业健康检查,包括尿铅、血红蛋白和血锌原卟啉测定.结果 部分工作场所空气中铅浓度超过国家职业卫生标准,铅作业工人中具有不同程度的神经衰弱症状和消化系统症状.162名铅作业工人中15人尿铅含量超过职业接触限值（≥0.34 μmol/L）,7人ZPP≥2.91 μmol/L,15人Hb下降,与对照组比较,差异有统计学意义（P＜0.01）.接触组浓度＞0.05 mg/m^3及接铅工龄在2 a～者,生物监测指标明显异常.结论 蓄电池厂的铅作业工人存在明显的职业危害,定期进行尿铅、血红蛋白和血锌原卟啉生物监测十分必要,可以早期发现职业健康损害,预防铅中毒的发生.
[Objective] Biological monitoring was conducted on the urinary lead, Hb and ZPP of the lead - exposed workers in a storage battery factory. [ Methods ] The lead concentration in the workplace air was determined; physical examination was conducted on the lead -exposed workers including the determination of urinary lead, Hb and blood ZPP. [ Results] The lead concentration in the air of some workplaces was higher than that of the national health standard; lead - exposed workers had the symptoms of nervous and digestive system; 15 workers among 162 had higher urinary lead level than the occupational exposure limit （ 〉 0.34 μmol/L）, 7 workers had higher ZPP （ 〉12.91 μmol/L） , and 21 workers had lower Hb levels, which were significantly different in comparison with the control group （ P 〈 0. 01 ）. [ Conclusion ] There were obviously occupational hazards in the battery factories, it is necessary to conduct biological monitoring of urinary lead, Hb and ZPP among the lead - exposed workers in order to prevent lead poisoning.
