摘要 目的 探讨锰接触工人个体实际接触剂量与生物指标之间的关系,以寻找合适的早期生物学监测指标.方法 选择济南市某机车车辆厂电焊作业工人270名,收集其血液和尿液.原子吸收光谱法测定血锰、尿锰和个体锰接触剂量;高效液相色谱荧光法测定尿中高香草酸(HVA)和香草扁桃酸(VMA);对各指标进行相关性分析.结果 个体锰接触剂量(CTWA)为0.005 5~1.957 7mg/m3,平均浓度为(0.25±0.31)mg/m3;接锰工人尿锰浓度为0.011 2~2.447 2μg/mg Cr,平均(0.22±0.31)μg/mg Cr;血锰浓度为0.06~38.70 μg/ml,平均(3.94±6.66)μg/ml;尿HVA浓度为0.102~4.780 μg/mg Cr,平均(1.01±0.78)μg/mg Cr;VMA浓度为0.032~2.768 μg/mg Cr,平均(0.61±0.35)μg/mg Cr.个体锰接触剂量与血锰、尿锰、尿中VMA之间均无相关性(P>0.05);个体锰接触剂量与尿中HVA呈负相关,差异有统计学意义(r=-0.168,P<0.01).结论 血锰、尿锰、尿中VMA均不能作为评价锰接触的接触生物标志物;尿中HVA可以作为评价锰接触的效应生物标志物.
