摘要
为明确松花江水体中内分泌干扰物的污染状况,利用固相萃取富集-气质联机/重组基因酵母对松花江全江11个典型断面进行全面采样分析.结果表明:江水中∑5ES质量浓度在6.59～30.97 ng/L,平均值为17.23 ng/L,出现最大质量浓度的位置是达连河排污口,雌酮(E1)和雌二醇(E2)是其中贡献最大雌激素,其质量浓度范围为1.54～6.34和1.86～20.78 ng/L,主要来源于城市污水;所有采样点均检出了壬基酚(NP)、辛基酚(OP)和双酚A(BPA),其质量浓度范围分别为236.3～1067.9、3.07～256.10和13.0～206.5 ng/L,均值为512.8、34.1和52.8 ng/L,其质量浓度均高于雌激素,主要来源于生活污水和工业废水;松花江水体的雌激素活性为0.50～26.16 ng/L,最大值出现在哈下采样点,生活污水是雌激素活性的一个重要来源,其他采样点EEQ质量浓度均小于3.60 ng/L,其质量浓度与国内外河流处于同一污染水平,但存在潜在的生态安全问题.
For determining the pollution status of endocrine disrupting compounds（EDCs） in Songhua River,solid phase extraction（SPE） followed by GC-MS/Yeast Estrogen Screen（YES） assay were used to analyze the EDCs concentration at 11 sampling sites of Songhua River.The results indicated that total five estrogen ∑5ES was in the range of 6.59-30.97 ng/L,the average value was 17.23 ng/L,and the water from Dalian river outfall had the highest ∑5ES.Estrogen（E1） and 17β-estradiol（E2）,which were mainly from urban sewage and contributed most of all estrogen and their concentrations,were in the range of 1.54-6.34 and 1.86-20.78 ng/L,respectively;Nonylphenol（NP）,octylphenol（OP） and bisphenol A（BPA） were detected in all the sampling sites,with the mean values of 512.8,34.1 and 52.8 ng/L,respectively,which were mainly from the domestic sewage and industrial wastewater;The estrogenicity of river water detected by YES was in the range of 0.50-26.16 ng/L,and the highest EEQ occurred at the Haxia sampling site.The EEQ at other sampling site was all below 3.60 ng/L,which was at the same pollution level with other river,but it also existed the potential problems of ecological security in Songhua River.
