摘　　要：对石岐河表层水和沉积物中的20种取代芳烃进行了测定。结果表明,取代芳烃在表层水和沉积物中的含量范围分别为0.07~0.33μg/L、ND^5.72μg/g;水中取代芳烃的空间分布与沉积物相似,均呈现出中间高两边低的趋势。表层水中检出的取代芳烃均未超出地表水环境质量标准;与其他地区相比,石岐河表层沉积物中取代芳烃含量较低,生态风险也并不显著。Substituted aromatic hydrocarbons in water and sediments samples from Shiqi River were analyzed. Their contents were O. 07 ~ 0. 33 μg/L and ND - 5.72μg/g. The spatial distribution of water was similar to those of sediments. Substituted aromatic hydrocarbons in water did not exceed the standard of surface water environment quality. Compared with other regions, the content of substituted aromatic hydrocarbons in sediments of Shiqi River was in a relatively low level. The ecological risks of substituted aro- matic hydrocarbons in sediments were also investizated bv risk uuotient, and the results indicated that they were in a lnw level.
