Abstract:
Objective To investigate the exposure to benzene,methylbenzene,and dimethylbenzene in workers in a petrochemical enterprise in Shanghai,China,and to conduct occupational hazard risk assessment.Methods The environmental monitoring data on benzene series in the workplace of this petrochemical enterprise from 2010 to 2014 were collected,as well as workers' general status.The inhalation risk assessment model developed by United States Environmental Protection Agency (EPA) was used for risk assessment to determine the occupational hazard risk level of benzene,methylbenzene,and dimethylbenzene.Results The pass rate of the monitoring concentration of benzene,methylbenzene,and dimethylbenzene in the workplace of this petrochemical enterprise was 100％.The results of the EPA model showed that benzene had a high carcinogenic risk,benzene and dimethylbenzene had a high non-carcinogenic risk,and methylbenzene had a low noncarcinogenic risk.Conclusion The workers exposed to benzene in this petrochemical enterprise have a high health risk,and the EPA model can be used for occupational hazard risk assessment in chemical industry.
