To Investigation of industrial sites involving coal tar pitch to detect PAHs in the occupational environment and to assess their occupational health risks to workers. Taking coal tar pitch enterprises as the research object, and making the occupational health field investigation and inspection. Detecting the 16 PAHs in the samples by high performance liquid chromatography (HPLC) , analyze the PAHs exposed dose of the workers in the place, and using cumulative toxic equivalent quantity method, loss of life expectancy method and carcinogenic risk factor method to assessment worker's occupational health risk. In the 15 posts involved, Some workers' exposed to the total concentration of PAHs is higher than others, the maximum exposure concentration is 1931.45ng/m3. There are different hazard risk levels in different working post due to different processes.The lifetime risk of workers is significantly higher than the acceptable range. Some workers has higher carcinogenic risk and workers' life expectancy loss is up to 1033.95 hours. Part of the coal tar pitch workers exposed to higher concentrations of PAHs, and beyond the occupational exposure limits.And there is a high occupational health risk due to high exposure to PAHs.
对涉及煤焦油沥青的工业场所进行调查，以检测职业环境中的多环芳烃（PAHs），并评估其对工人的职业健康风险。以煤焦油沥青企业为研究对象，开展职业健康现场调查与检测。采用高效液相色谱法（HPLC）检测样品中的16种多环芳烃，分析该场所工人的多环芳烃暴露剂量，并运用累积毒性当量法、预期寿命损失法和致癌风险因子法评估工人的职业健康风险。在所涉及的15个岗位中，部分工人的多环芳烃总暴露浓度高于其他工人，最大暴露浓度为1931.45ng/m³。由于工艺不同，不同工作岗位存在不同的危害风险水平。工人的终生风险显著高于可接受范围。部分工人具有较高的致癌风险，工人的预期寿命损失高达1033.95小时。部分煤焦油沥青工人接触到较高浓度的多环芳烃，超出职业接触限值。由于多环芳烃的高暴露，存在较高的职业健康风险。
