摘　　要：对石岐河17个监测断面表层水中20种取代芳烃进行研究。结果表明,石岐河水中取代芳烃为ND^0.51μg/L,均值为0.20μg/L。与国内其他地区相比,石岐河水中取代芳烃含量处于较低水平。通过风险商模型对石岐河水中检出的取代芳烃进行生态风险评价后发现,取代芳烃对石岐河的生态风险低,但需要对4、8、11、12、15、16号断面相关环境进行观察。对4种已报道非致癌剂量或致癌斜率因子的取代芳烃进行健康风险评价后发现,石岐河水中检出的取代芳烃非致癌风险和致癌风险并不严重,不会对人体健康产生明显的影响。Substituted aromatic hydrocarbons in water samples collected from Shiqi River were analyzed. The range of total substituted aromatic hydrocarbons was ND-0. 51 μg / L. Comparison with the results of other research areas,the pollution of substituted aromatic hydrocarbons was in the low level. The ecological risks of substituted aromatic hydrocarbons were also investigated by risk quotient,and the results indicated that they were in a low level. The health risks of four kinds of substituted aromatic hydrocarbons with reference doses or slope factor were also investigated. It can be considered that substituted aromatic hydrocarbons would not cause obvious health hazard to human beings currently.
