Abstract:
Objective: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.
Methods: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.
Results: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.
Conclusion: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.
