摘要
采用液相色谱-串联质谱法测定徐州地区地下水中内分泌干扰物,并用雌二醇当量EEQ计算法和风险熵RQ计算法分别对其活性和生态风险水平分析评价。结果表明,徐州地区地下水中不含雌酮(E1)、雌二醇(E2)、雌三醇(E3)、炔雌醇(EE2)等内分泌干扰物,只含有双酚A(BPA),且最高值达26.45 ng/L,提出应把BPA作为控制重点。
The concentration of estrogenic endocrine disrupting chemicals in groundwater in Xuzhou were determined by LC-MS,and their estrogenic activities and ecological risk were evaluated by estradiol equivalency( EEQ) and risk quotient( RQ),respectively. Except bisphenol A,estrone,estradiol,estriol and 17α-ethinylestradiol were undetected. The maximum concentration of BPA was 26. 45 ng / L of all sampling sites. Therefore,BPA should be controlled primarily.
