| 摘 要： | 以异狄氏剂、狄氏剂和p,p'-滴滴涕3种持久性有机氯农药为研究对象,通过室内模拟实验,验证了三油酸甘油脂-醋酸纤维素复合膜(TECAM)富集水中自由溶解态疏水性有机物的假设,研究了水中溶解性有机碳对TECAM富集3种有机氯农药的影响,并与相同暴露条件下日本青鳉鱼的富集结果进行了比较.结果表明,TECAM只富集水中自由溶解形态的疏水性有机物;水中存在的溶解性有机碳会降低3种有机氯农药被TECAM和青鳉富集的可利用性;TECAM和青鳉的富集结果有很好的可比性.因此,TECAM能够用来预测疏水性有机污染物在不同溶解性有机碳含量的水中被鱼体富集的生物有效性.

| Abstract: | Three organochlorine pesticides(OCPs)-endrin,dieldrin,and p,p'-DDT-were used as target compounds to test the hypothesis that triolein embedded cellulose acetate membrane(TECAM) only extracts freely dissolved hydrophobic organic compounds(HOCs).The effect of dissolved organic carbon(DOC) on the bioavailability of the OCPs was also examined through accumulation study with TECAM and Japanese medaka(Oryzias latipes).Results showed that TECAM only extracted the freely dissolved HOCs and the presence of DOC in water reduced the availability of HOCs to both TECAM and Japanese medaka.The effect of DOC on the accumulation profiles of the three target compounds in TECAM and medaka was similar.Therefore,TECAM can be used to predict the effect of DOC on the bioavailability of HOCs in fish. |
