Abstract

This study examined antioxidant system responses and gastrointestinal pathological changes related to alpha olefin sulfonate (α-OS) toxicity in generated oxidative stress. , self-bred fish, including the control, were exposed to α-OS concentrations observed in the field (0.05, 0.10, 0.15, and 0.20 mg/l) for 30 days. Sigma-Aldrich test kits were used to assess reduced glutathione -transferase (GST) spectrophotometrically, while abnormal changes or damage in the gastrointestinal tract (GIT) were examined under a microscope. In plasma, α-OS exposure increased GST activities by 73%, varying with dose and duration. Glutathione (GSH) activity decreased by 26% but had few impacts. Increasing α-OS concentration and exposure duration led to histopathologic damage in the GIT, while the control fish had a normal GIT architecture. Fish absorb surfactants easily through their skin and gills, and blood circulates them to their organs. Fish contamination lowers human resistance by altering numerous enzymes through the food chain. When other contaminants are present in high amounts, the combined toxicity damages biota more than either pollutant alone. Any detergent contamination in coastal waters should be addressed seriously because the organisms that are low on the food chain and other sensitive ones will be eliminated even at low concentrations.

摘要

本研究检测了与α-烯烃磺酸盐(α-OS)在产生氧化应激时的毒性相关的抗氧化系统反应及胃肠道病理变化。将包括对照组在内的自育鱼类暴露于在野外观察到的α-OS浓度(0.05、0.10、0.15和0.20毫克/升)下30天。使用西格玛奥德里奇测试试剂盒通过分光光度法评估还原型谷胱甘肽转移酶(GST),同时在显微镜下检查胃肠道(GIT)的异常变化或损伤。在血浆中,α-OS暴露使GST活性增加了73%,其随剂量和持续时间而变化。谷胱甘肽(GSH)活性下降了26%,但影响较小。α-OS浓度和暴露持续时间的增加导致GIT出现组织病理学损伤,而对照鱼的GIT结构正常。鱼类通过皮肤和鳃很容易吸收表面活性剂,并通过血液循环将它们输送到各个器官。鱼类受到污染会通过食物链改变多种酶,从而降低人类的抵抗力。当存在大量其他污染物时,联合毒性对生物群的损害比任何一种污染物单独造成的损害都更大。沿海水域的任何洗涤剂污染都应得到严肃对待,因为即使在低浓度下,食物链底层的生物和其他敏感生物也会被消灭。
