某冶炼厂铅职业接触者血铅水平的影响因素分析

Analysis of Factors Influencing Blood Lead Levels of Workers with Occupational Lead Exposure in A Smelting Plant

目的分析某冶炼厂影响铅职业接触者血铅水平的因素。方法采集观察对象静脉血,用原子吸收光谱法测定血铅浓度,用SPSS16.0统计软件进行血铅影响因素的分析。结果铅职业接触者的血铅水平显著高于非职业接触者;不同年龄、性别、工龄、工作车间和岗位的职业接触者血铅水平差异均有统计学意义。结论该冶炼厂铅职业接触者血液中铅水平显著升高;铅职业接触者的年龄、性别、工龄、作业车间和岗位均为影响血铅水平的因素。

[Objective]To analyze the factors influencing the blood lead levels of workers with occupational lead exposure in a smelting plant.[Methods]The blood specimens of objects were collected and determined for blood lead levels by graphite furnace atomic absorption spectrometry.The results were analyzed by SPSS 16.0.[Results]The blood lead levels of workers with lead exposure were significantly higher than that of workers without lead exposure.The differences of blood lead levels were significant between lead exposed workers with different age,sex,length of service,workshop and working position.[Conclusion]The blood lead levels of lead exposed workers from this smelting plant are significantly high.Their age,sex,length of service,workshop and working position are the factors influencing the blood lead levels.
