铅作业工人293名血铅水平的调查

目的了解铅作业工人体内铅含量水平。方法采用石墨原子吸收法测定血铅含量,采用希斯美康1000 i血球仪测定血红蛋白含量。结果 293名铅作业工人中血铅超过1.9μmol/L有192人;超标率为65.53%;男工和女工的血铅水平和血红蛋白水平都存在负相关。结论 293铅作业工人血铅水平较高,企业应改进生产工艺,增强防护措施,对血铅超标者进行驱铅治疗,定期对工人进行体检。

Investigation on The Blood Lead Levels of 293 Workers with Lead Exposure

[Objective]To understand the in vivo lead levels of workers with lead exposure.[Methods]Graphite furnace atomic absorption spectrophotometer and blood analyzer XS-1000i were used for determination of blood lead level and hemoglobin level respectively.[Results]Of 293 workers,the blood lead level of 192 workers（65.5%） was over 1.9 μmol/L.The results showed negative correlations between blood lead level and hemoglobin level on male and female workers.[Conclusion]The blood lead level is relatively high in 293 lead-exposed workers.The enterprises should improve manufacturing technique,enhance protective measures,eliminate lead in workers with high lead level and perform health examination on workers regularly.
