| 摘 要： | 利用急性接触试验和人工土壤试验分别研究了壬基酚聚氧乙烯醚（NPEO）对赤子爱胜蚓（Eisenia foetida）的致死性和氧化损伤.急性接触试验结果显示,NPEO对赤子爱胜蚓的48 h毒性半致死剂量p（48 h,LD50）为0.58 mg·L^-1;人工土壤试验结果显示,NPEO可诱导赤子爱胜蚓CAT酶活力、GST酶活力、GSH含量和氧化产物（MDA）含量上升,暴露28 d时,NPEO浓度与赤子爱胜蚓CAT酶活力、GST酶活力、GSH含量和MDA含量呈正相关,且均存在显著的剂量-效应关系（P＜0.05）,NPEO剂量增加对赤子爱胜蚓SOD酶活性和Cu-Zn SOD酶活性有轻微抑制作用.以上结果表明NPEO在亚致死暴露浓度下＜0.50 mg· kg^-1）会对赤子爱胜蚓产生生理胁迫并导致一定程度的氧化损伤.

| Abstract: | An acute contact test and an artificial soil test was conducted to study lethal and oxidizing effects of nonylphenol polyethylene glycol ether （NPEO） on earthworm （Eisenia foetida）.Results show that the 48-h median lethal dose of NPEO was 0.58 mg · L^-1.The artificial soil test shows that NPEO induced the activity of CAT and GST and increased the content of GSH and MDA.After 28 hours of exposure,CAT and GST activities and GSH content was found to be positively related to the concentration of NPEO （P〈 0.05）.However,increased NPEO concentration slightly suppressed the activities of SOD and Cu-Zn SOD.The above findings indicate that NEPO of sub-lethal dose may generate physiological stress and certain extent of oxidizing damage to the earthworms. |
