In the site risk characterization, it divides the hazard of pollutants into carcinogenic risk and non carcinogenic hazard quotient, and analyzes the uncertainty in risk assessment, and suggests having a quantitative analysis by sensitivity analysis method. 在场地风险表征中,将污染物对人体的危害分为致癌风险和非致癌危害商,并分析了风险评价中的不确定性,建议以敏感性分析法来进行定量分析。
The joint probability risk of the 8 PAHs was calculated based on the sum of equivalent concentrations derived from calculated equivalence factors and compared with conventional approach of hazard quotient. 进一步,基于“等效系数”概念,计算各样点多环芳烃的等效总浓度,用概率风险评价方法分析了8种多环芳烃联合作用的总生态风险,并与风险商(RQ)结果对比。
