• 摘要：用固相萃取(SPE)/高效液相色谱法(HPLC)同时测定了松花江水中的13种典型内分泌干扰物(EDCs).结果表明,哈尔滨段江水中雌三醇(E3)、雌二醇(E2)、雌酮(E1)、乙炔雌醇(EE2)及乙烯雌酚(DES)5种雌激素物质的浓度普遍较高,最高可达66ng·L^-1;酞酸二甲酯(DMP)、酞酸二乙酯(DEP)、酞酸二正丁酯(DnBP)及酞酸二(2-乙基己基)酯(DEHP)4种酞酸酯丰度最大,其中DnBP浓度最高可达330μg·L^-1;4-正壬基酚(4-n-NP)、带支链的对壬基酚(NP)及4-叔-辛基酚(4-t-OP)3种烷基酚的浓度范围为25～1261ng·L^-1;双酚A(BPA)浓度变化较小,保持在20～50ng·L^-1之间.经与相关报道比较,初步认为松花江水中雌激素类物质及酞酸酯污染较为严重,应当引起有关部门的警惕.

• Abstract：Solid phase extraction/high performance liquid chromatography was used for simultaneous determination of 13 representative endocrine disrupting chemicals (EDCs) in Songhua River water.It was observed that the concentrations of 5 estrogens,estriol(E3),17β-estradiol(E2),estrone(E1),17α-ethynylestradiol (EE2) and diethylstilbestrol (DES) were rather high over the Harbin reaches of the river,with the maximum content reaching 66 ng·L^-1.Dimethyl phthalate (DMP),diethyl phthalate (DEP),di-n-butyl phthalate (DnBP) and di-(2-ethylhexyl)phthalate (DEHP) were more abundant than other EDCs,and DnBP had the highest concentration at 330 μg·L^-1.Contents of 3 alkylphenols,4-n-nonylphenol(4-n-NP),branched p-nonylphenol (NP) and 4-tert-octylphenol(4-t-OP)were in the range of 25～1261 ng·L^-1.The concentrations of bisphenol A(BPA) were relatively stable,in the range of 20～50 ng·L^-1.In comparison to the concentrations of EDCs reported in the literature,these results demonstrate that the pollution of estrogens and phthalic acid esters(PAEs)is serious and needs special attention.
