目的对某蓄电池厂355名铅作业工人进行尿铅检测,了解该蓄电池厂工人体内铅负荷情况,筛查观察对象,为制定切实可行的预防措施提供依据。方法按照WS/T 17-1996《尿中铅的双硫腙分光光度测定方法》进行尿中铅性检测,并进行统计分析。结果在355份尿样检测结果中,尿中铅含量超标者共20人,超标率5.63%;男性超标率高于女性,但差异无统计学意义(P>0.05);不同工种和不同工龄工人间超标率差异均有统计学意义(P<0.05)。结论该蓄电池厂工人尿铅超标率仍处于较高水平,因此,应加强工人的职业健康监测工作,并改善车间环境,同时提高工作人员在生产中自我防护意识,保护职工身体健康。
Objective To test the urine lead level of 355 lead workers in a battery factory to understand the lead load of the battery factory workers and to screen the objects for observation so as to provide basis for making feasible preventive measures. Methods According to WS / T 17-1996, “Determination of lead in urine by dithizone spectrophotometric method” for urinary lead detection and statistical analysis. Results Among the 355 urine samples, the urinary lead levels exceeded 20 in total, exceeding the rate of 5.63%. The over-standard rate of males was higher than that of females, but the difference was not statistically significant (P> 0.05). Among different types of workers and different working-age workers There was significant difference between the exceeding standard rate (P <0.05). Conclusion The urinary lead excretion rate of the battery factory workers is still at a high level. Therefore, occupational health monitoring should be strengthened and the workshop environment should be improved. At the same time, workers should be more aware of their self-protection in production and protect their health.
