Keyword:  重金属岗前职业健康检查尿液负荷水平;
Abstract: 目的 了解上海市岗前职业健康检查人群尿中持久性有毒重金属及微量元素铜的负荷水平.方法 采用多阶段分层整群随机抽样法,抽取1 183名非职业暴露人员,对其岗前职业健康检查所得尿液中6种主要重金属水平进行分析.结果 尿砷、铜、铅、锰、汞平均值分别为0.14 μmol/L、0.07 mg/L、0.106 μmol/L、0.011 mg/L、0.013 μmol/L,均在现有参考值范围内.尿铬平均值为0.031 mg/L,高于现有参考值.尿铅水平P95(0.177 μmol/L)、尿锰水平P95(0.012 mg/L)明显低于现有正常参考值.尿铬水平P95(0.181 mg/L)明显高于现有正常参考值.尿砷、铬、铜、铅、锰、汞水平在各年龄组间差异均无统计学意义(P>0.05).尿铬、铅、锰、汞水平在男女性别间差异无统计学意义(P>0.05).结论 应重视铬在本地区人群的负荷水平.在职业健康检查或职业病诊断中采用各年龄段和性别间统一的尿铬、铅、锰、汞参考值是可行的;应进一步验证尿砷、尿铜在男女性别间的统计学差异.
