Effects of Iron Chloride/Zeolıte on GST of Rainbow Trout (Oncorhynchus mykiss)’s Kidney Tissue

Abstract

Aquatic ecosystems have been negatively affected by the contamination of ground and surface waters as a result of various activities. Due to the ferrous chloride (FeCl₂), which is used as the reducing agent for the organic synthesis reactions in the contamination of water column and sediment, iron salts may be very toxic for some aquatic organisms. In order to minimize these effects, natural products such as zeolite have been widely used in recently years. For this reason, rainbow trout were exposed to FeCl₂ and/or zeolite ((FeCl₂ (0.002 mg/l)(A), FeCl₂+zeolite (0.002 mg/l+1 gr/l) (B), zeolite (1 gr/l) (C) and control (without FeCl₂ and/or zeolite (D)).  At the end of the exposure time,  28 days and their oxidative stress responses were investigated. At the end of the treatment period, glutathione-S-transferase (GST) activity was determined in the samples taken from kidney. GST values for kidney tissues were found statistically important in the control and treatment groups (p<0.01).
