摘　　要：本研究基于逸度方法的Level Ⅲ环境多介质模型对延吉市BaP的环境归趋进行了模拟,探究了季节变化对BaP归趋的影响,并进行了致癌风险评价。结果表明:模型计算值与研究区实测值相吻合,模型参数选取合理可靠;延吉市地区5种环境相中BaP浓度较高的环境相为土壤、水和沉积物相,大气和水体中BaP呈现出夏季高冬季低的特点,而在固相环境中其特点为冬季高于夏季;终生致癌风险评价结果表明延吉市地区BaP不存在致癌风险。The Level Ⅲ environmental multi-media model based on fugacity method was used to simulate BaP environmental trend in Yanji city,explore the influence of seasonal change on BaP trend and evaluate the carcinogenic risk of BaP. The results show that the calculated concentration of the model is in good agreement with the measured value of BaP in the study area and the model parameters are reasonable and reliable. The environmental facies with higher BaP concentrations are soil, water and sediment facies;BaP is higher in summer and lower in winter in atmosphere and water, but higher in winter than in summer in solid environment. The results of ILCR show that there is no carcinogenic risk in BaP in Yanji.
