%X Lots of uncertainties lie in the procedure of environmental risk assessment (ERA) and how to analyze them exactly is studied comprehensively. Based on the investigation of petroleum contamination in a contaminated site, the representative benzene contaminant in soil was selected to analyze uncertainty of environmental risk resulting from drinking and inhalation exposure routes, using the Monte-Carlo simulations. According to the analysis results, the total health risk average value caused by benzene contamination from the alkene factory is 1.18×10-4 for the people living on the district A, which is more than the risk limit of U.S.EPA 10-6 and means contamination hazard to health. In four different areas of the alkene factory, the main source of risk comes from the cracking equipments with 1.17×10-4. With the impact factors of the uncertainty, the contamination harm to the human health's probability is different referring to the different risk level, which is a criteria value meaning no harm to health issued by different institution. The study results provide an important foundation of effective control and remediation actions of contaminated sites.
