离子型和非离子型表面活性剂，氧化应激和胆碱酯酶活性的涡虫的影响

摘要

八广泛使用的表面活性剂（十六烷基三甲基溴化铵CTAB法，氯化苄甲乙氧铵; Hyamine1622，4 - 壬基酚，NP，辛基苯酚乙氧基化物;的Triton X-100，十二烷基苯磺酸钠; LAS，月桂基硫酸钠; SDS，pentadecafluorooctanoic酸，全氟辛酸铵，全氟辛烷磺酸，全氟辛烷磺酸）重新审视自己的急性毒性和氧化应激的影响和胆碱酯酶（CHE）在日本三角涡虫的活动。 8的表面活性剂，以涡虫急性毒性之间的差异是至少在范围

3个数量级。据估计，48小时LC50表面活性剂的毒性等级SDS> NP> LAS>

Hyamine1622> CTAB>的Triton X-100>全氟辛烷磺酸PFOA。根据96小时LC50表面活性剂的毒性排名如下：SDS> CTAB> NP> LAS> Hyamine1622>的Triton

X-100>全氟辛烷磺酸PFOA。有过氧化氢酶的活性显着增加

涡虫暴露在LAS名义浓度的0.5或1毫克升？1和1 after48小时暴露在5年或10毫克升的名义浓度的全氟辛烷磺酸。车活动中发现的抑制作用Hyamine1622涡虫暴露在所有浓度测试，标称浓度为10毫克升？PFOS，PFOA的名义浓度50毫克或100毫克升？和NP标称浓度为0.5 ？1毫克升。在标称浓度的Triton

X-100涡虫暴露在车活动中也观察到显著增加

5毫克升1。暗示的胆碱酯酶抑制NP，PFOS和PFOA在水产动物的神经和行为的影响，需要进一步调查。

介绍-introduction

表面活性剂广泛使用在日常生活中的个人护理和家用产品，以及在各种工业应用。其结果是，大量的表面活性剂通常排出大量污水处理厂或直接向水生环境中有没有污水处理的地方。事实上，很多表面活性剂及其降解产物已遍布世界各地，在污水排放，污水处理厂的污水，天然水和沉积物（英，2006年）。因为很多表面活性剂是无处不在（英等人，2002; Venhuis和Mehrvar，2004年），这些化学品的潜在的毒性作用吸引了大量的研究关注在过去的几十年（亚伯，1974年刘易斯和Suprenant，1983年刘易斯，1991）。然而，以前的研究结果已主要集中在阴离子表面活性剂，有有限的毒物的资料对其他类型的表面活性剂，或一些新兴的表面活性剂，如4 - 壬基苯酚（NP），pentadecafluorooctanoic辛酸（PFOA）或全氟辛烷磺酸（PFOS）。
