摘　　要：为了提高地下水健康风险评价的准确性,在对目标污染物进行健康风险评价时需考虑关联因子的影响。文章对健康风险评价模型进行改进,提出了关联因子影响下目标污染物浓度的校正方程,并用四川德阳地区地下水中目标污染物Cr(Ⅵ)和关联因子挥发酚的检测数据进行验证。得出校正后Cr(Ⅵ)的健康风险值比校正前减小21.86%,与当地未见Cr(Ⅵ)毒害的人群相符。When health risk assessment is performed towards the target pollutants, effects of the correlation factors should be taken into consideration for improving the accuracy of health risk assessment of the groundwater. In this study, on the basis of health risk assessment model, the model of health risk assessment for the target contaminants is improved and correction equation for the concentration of the target contaminants under the influence of correlation factors is proposed. Furthermore, detection data of Cr（VI）, the target pollutant in the groundwater located in Deyang region of Sichuan Province, and volatile phenol, the correlation factor, are used for verification. The results show that the corrected health risk value of Cr（VI） decreases by 21.86% in accordance with the fact that no local residents poisoned by Cr（VI） are found there.
