摘　　要：针对淡水环境中甾体雌激素对水生生物的毒理学影响,文中以雌二醇(E2)和乙炔基雌二醇(EE2)为研究对象,利用其对淡水生物系统中各营养级物种的慢性毒性效应浓度,建立基于对数-累积正态分布的物种敏感度分布模型。获得E2和EE2的5%危害质量浓度(HC_(5))分别为0.1137μg/L和0.0010μg/L,并推导出E2和EE2的基准连续浓度(CCC)分别为0.1137μg/L和0.0010μg/L。According to the pollution of steroid estrogen in fresh water environment at home,estradiol(E2)and ethinylestradiol(EE2)were studied in this paper as objects,which develops a species sensitivity distribution(SSD)model using toxicity values of E2 and EE2 on each trophic level of freshwater biological systems.Using logarithm-accumulation normal distribution based on the chronic toxicity value,the hazardous concentration for 5%of the species(HC5)of E2 and EE2 were 0.1137μg/L和0.0010μg/L,the criteria continuous concentration(CCC)of E2 and EE2 derived were 0.1137μg/L和0.0010μg/L,respectively.
