“…Reduction in GSH concentration in this study might be explained by the increased concentrations of detergents that induce severe oxidative stress may be either due to suppression of GSH levels in response to xenobiotics due to loss of adaptive mechanisms or oxidation of GSH to GSSG to eliminate the produced ROS ( Bradai et al, 2014 ). Decrease in the activity of CAT and SOD and concentration of GSH in the present study was harmonized with the investigations proceeded on Ruditapes phillipinarum treated with non-ionic surfactant NPEO ( Alvarez-Munoz et al, 2006 ), Solea senegalensis ( Alvarez-Munoz et al, 2007 ), Anabas testudineus ( Nair et al, 2017 ), Danio rerio ( Sobrino-Figueroa, 2013 ) exposed to commercial detergents and LAS, Prochilodus lineatus ( Modesto and Martinez, 2010 ) exposed to Roundup Transorb (RDT) which is a glyphosate-based herbicide containing a mixture of surfactants, Oreochromis niloticus ( Atli and Canli, 2010 ) exposed to sublethal concentrations of metals and Melanotaenia fluviatilis ( Miranda et al, 2020 ) subjected to perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA), which are a group of persistent anthropogenic organic surfactants. However, the present investigation conflicted with the findings of Shukla and Trivedi (2018) which showed elevation in both SOD and CAT activities in Channa punctatus and the stimulating effect of LAS whether was alone or additively with detergents on oxidative stress.…”
