摘　　要：为有效保护黄河入海口流域水环境质量和水生态健康,并为硒(Se)的环境管理和风险评估提供数据支撑和科学依据,本研究使用基于组织的基准(tissue based criteria,TBC)并结合相平衡分配法(equilibrium partitioning approach,EqPA)初步推导了Se的沉积物质量基准(sediment quality criteria,SQC),评估了黄河入海口流域沉积物中Se的生态风险水平。测定了黄河入海口8个采样点的表层沉积物及其孔隙水Se含量,结果表明,沉积物中Se的浓度范围为2.13~3.41 mg/kg,平均浓度为2.95 mg/kg;Se在固相和水相之间的分配系数为2757 L/kg,且Se的SQC值为0.80 mg/kg。基于本研究中推导的SQC,黄河入海口流域沉积物中Se的生态风险水平较高,可能会对水生态系统产生有害作用,需要开展进一步的研究。To effectively protect the water environmental quality and water ecological health of the Yellow River Estuary,and to provide data support and scientific basis for environmental management and risk assessment of selenium(Se),this study was conducted to derive the sediment quality criteria(SQC)for Se by using the tissue based criteria(TBC)method combined with the equilibrium partitioning approach(EqPA),and to assess the ecological risk level of Se in the sediment of the Yellow River estuary basin.This study measured the Se content of surface sediments and their pore water at eight sampling sites in the Yellow River estuary.The results showed that the concentration of Se in sediments ranged from 2.13 to 3.41 mg/kg,with an average of 2.95 mg/kg;the distribution coefficient of Se between the solid phase and the aqueous phase was 2757 L/kg,and the SQC value of Se was 0.80 mg/kg.The results indicated that the ecological risk level of Se in sediments of the Yellow River Estuary is high,which may have harmful effects on the water ecosystem and requires further research.
