摘要
目的对涉及煤焦油沥青的工业场所进行调查，检测工人所处职业环境中的PAHs含量并评估其对工人产生的职业健康风险。方法以煤焦油沥青使用企业为研究对象，对其进行职业卫生现场调查与检测，用高效液相色谱法检测样本中的16种PAHs，分析工人在该场所中PAHs接触剂量，并用累积毒性等效剂量法、预期寿命损失法、致癌风险系数法等方法进行职业健康风险评估。结果在所涉及的15个岗位中，部分工种所接触的总PAHs浓度较高，最高接触浓度为1 931.45 ng/m^3。不同岗位因工艺不同存在不同的危害风险水平，工人的终身超额危险度明显超过可接受范围，部分工种存在较高致癌风险，作业工人的成年人预期寿命损失最高值达到1 033.95小时。结论部分煤焦油沥青职业工人所接触的PAHs浓度较高，超出职业接触限值，并存在较高的职业健康风险。
ObjectiveTo Investigation of industrial sites involving coal tar pitch to detect PAHs in the occupational environment and to assess their occupational health risks to workers.MethodsTaking 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.ResultsIn the 15 posts involved, Some workers＇ exposed to the total concentration of PAHs is higher than others, the maximum exposure concentration is 1931.45ng/m^3. 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.ConclusionPart 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.
