Abstract
目的探讨焦炉工职业性多环芳烃暴露特征.方法个体采样、高效液相色谱法测定作业环境中多环芳烃含量,以分析焦炉工职业暴露特征,并引入毒性当量因子概念,评价焦炉工职业性多环芳烃暴露的致癌潜能.结果焦化厂炉顶工多环芳烃职业暴露水平明显高于炉侧工和炉底工,差异有统计学意义(P＜0.05);焦炉工多环芳烃职业暴露中非致癌性物质所占比例＞70%,致癌性物质中苯并(a)芘(B[a]Py)占总B[a]Py等当量浓度的65.5%～72.4%;多环芳烃职业暴露总量和B[a]Py及芘含量呈正相关(r2分别为0.84和0.94,P＜0.05).结论焦炉工职业性多环芳烃暴露水平较高且具有一定的致癌潜能,致癌性物质以B[a]Py为主.
