摘要
采用固相萃取-衍生化-气相色谱法对奉化江中三个采样点的环境雌激素含量进行了检测,共检测到7种环境雌激素。其中长丰桥采样点的4-壬基酚(4-NP)含量高于其他采样点,但未检测到雌三醇(E3),而在其下游2个采样点中均检测到了E3,推测长丰桥附近可能存在违排现象。最后对3种残留量较大的双酚A(BPA)、邻苯二甲酸二乙酯(DEP)、邻苯二甲酸二丁酯(DBP)进行了风险评价,三个采样点的风险指数均小于1,故暂不会对人体造成影响。
Seven kinds of environmental estrogens were detected in Fenghua River by solid phase extraction,derivatization and gas chromatography. The content of 4-nonylphenol( 4-NP) in Changfeng Bridge sampling site was higher than that in other sampling sites,but Estriol( E3) was not detected. E3 was detected in both downstream sampling sites,suggesting that there might be violation of emission near Changfeng Bridge. Finally,three kinds of BPA,DEP and DBP with large residues were evaluated. The risk indices of the three sampling points were all less than 1,and it will do no harm to human.
