铅作业工人血铅、尿铅和血常规检测结果分析

目的比较铅作业工人和非铅作业工人血铅、尿铅和血红蛋白浓度的差异。了解长期低铅作业工人的健康状况。方法对2009年天津市某蓄电池厂400例铅作业工人和120例非铅作业工人分别进行血铅、尿铅和血红蛋白浓度的测定,并对结果进行统计学处理。结果铅作业组血红蛋白浓度低于非铅作业组。而血铅、尿铅浓度均显著高于非铅作业组（P〈0.01）。并且血铅和血红蛋白浓度间呈负相关性（r=-0.442）,尿铅与血铅和血红蛋白间的相关性均不理想（r值分别为-0.026和-0.018）。结论长期低铅作业可导致人体血铅尿铅升高,血红蛋白降低,但尿铅浓度波动大,且影响因素多,不能精确反映体内铅积蓄量,结果与其他指标的相关性较差。

Blood Lead, Urine Lead and Blood Test Results of Lead Exposed Workers

[Objective]To compare the difference of levels of blood lead,urine lead and hemoglobin between workers with lead exposure and workers without lead exposure,and understand the health status of workers with long-term lead exposure.[Methods]Level determination of blood lead,urine lead and hemoglobin were performed on 400 workers with lead exposure and 120 workers without lead exposure from a storage battery factory in Tianjin in 2009.The results were analyzed statistically.[Results]Hemoglobin levels in lead-ex...
