【摘要】：目的分析蓄电池企业铅接触工人血铅水平对职业健康检查有关指标的影响。方法采用判断抽样法,以412名蓄电池企业铅接触工人为研究对象,根据血铅水平分为100.0、100.0~、200.0~、300.0~和400.0~μg/L组,分析血铅水平对工人的临床症状、心电图、尿常规、血压、肝功能和血常规等指标的影响。结果 412名工人血铅水平中位数和第25、75百分位数[M(P25,P75)]为169.0(76.6~320.4)μg/L,血铅超标(血铅水平≥400.0μg/L)率为12.6%,男性工人血铅水平高于女性工人[225.8(91.3,351.2)vs 131.0(64.6,248.9)μg/L,P0.01]。女性工人中,血铅水平100.0μg/L组的心电图异常率低于400.0~μg/L组(6.7%vs 41.2%,P0.005),血铅水平100.0μg/L组的舒张压水平低于300.0~μg/L组[(78.4±11.7)vs(72.6±5.6)mm Hg,P0.01]。Spearman相关分析结果显示,尿β2-微球蛋白水平与血铅水平无相关关系[秩相关系数(rS)=-0.044,P=0.82],诊断性驱铅试验24 h尿铅水平与血铅水平呈正相关关系(rS=0.657,P0.01)。结论血铅对女性心血管的影响较男性明显,常规的肝功能指标和尿常规(尿蛋白)指标不能早期反映铅的肝、肾毒性。

Methods 412 lead-exposed workers in battery enterprises were divided into two groups according to their blood lead levels: 300.0- and 400.0- 渭 g / L groups. The clinical symptoms, electrocardiogram, urine routine and blood pressure were analyzed. The effect of liver function and blood routine.
