低铅环境作业的铅危害研究

Lead Hazard Research for the Low Lead Environment Work

目的调查低铅环境作业铅危害现状并采取相应对策。方法采用现场职业卫生调查、健康检查和综合分析法等进行评价。结果 职业人群血铅值由高到低分别为铅冶炼工>放射人员>养路工>制造业工人(对照组)。低铅环境作业的放射工作人员、养路工血铅均值较高,与制造业工人及铅冶炼工人血铅差别有统计学意义(P<0.01)。结论以放射工作人员、养路工为代表的低铅环境作业的铅职业病危害应予以关注。

[Objective]To investigate the current status of hazards in low lead environment work and take corresponding countermeasures. [Methods]Field occupational health investigation,physical examination and the analysis by synthesis method were adopted for evaluation. [Results]The Occupational population blood lead levels from high to low respectively were the lead smelter radiation worker highway maintenance worker the manufacturing industry worker（control group）.In the low lead environment work,the blood lead average levels of radiation worker and highway maintenance worker were high,the difference with the lead smelting works and the manufacturing industry workers（P0.01）. [Conclusion]The low lead environmental works represented by radiation workers and road maintenance workers should be concerned about the occupational hazards of lead.
