目的了解铅对作业工人的健康影响,分析尿铅与血红蛋白和红细胞的关系。方法对202名铅作业工人和213名对照人群进行尿铅、血红蛋白和红细胞检测。结果铅作业组的尿铅≥0.34μmol/L的占70.8%,明显高于对照组(P<0.01);铅作业组血红蛋白明显低于同性别对照组(男性P<0.01,女性P<0.05);铅作业组红细胞与同性别对照组比较,差异无统计学意义(P>0.01)。多元回归分析表明,血红蛋白与尿铅水平呈负相关。结论长期职业接触铅可引起尿铅含量增高和血红蛋白降低含量,血红蛋白含量与尿铅水平呈负相关。
Objective To understand the health effects of lead on workers and analyze the relationship between urinary lead and hemoglobin and erythrocytes. Methods Totally 202 lead workers and 213 control subjects were tested for urinary lead, hemoglobin and erythrocytes. Results Lead (≥ 0.34μmol / L) in lead group was significantly higher than that in control group (70.8%) (P <0.01). Hemoglobin in lead group was significantly lower than that in same sex group (P <0.01 for male and P < There was no significant difference between lead group and control group (P> 0.01). Multiple regression analysis showed that hemoglobin was negatively correlated with urinary lead levels. Conclusion Long-term occupational exposure to lead can lead to an increase in urinary lead and hemoglobin, and a negative correlation between hemoglobin and urinary lead levels.
