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.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 25-1 261 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.
