Orginal research papers
Chlorpyrifos (CPF) is used intensively as an insecticide. There is a high risk of interference with the aquatic environment due to unconscious use and has a negative effects especially fish. In this study, the responses of rainbow trout (<em>Oncorhynchus mykiss</em>) and brown trout (<em>Salmo trutta fario</em>) exposed to the same pollutants have been evaluated and compared in terms of target organs. Fish were exposed to different concentrations of CPF (0.25, 0.5, and 1 µg L<sup>-1</sup>) through 21 days. After the process oxidative stress [superoxide dismutase (SOD), catalase (CAT glucose-6-phosphate dehydrogenase (G6PD), glutathione reductase (GR), glutathione-S-transferase (GST), glutathione peroxidase (GPx)], acetylcholinesterase (AChE) and malondialdehyde (MDA) have been measured in gill, kidney and liver tissues. CPF exposure led to a significant changes in the enzyme activities and decreased AChE in all tissues (<em>p</em><0.05). All antioxidant enzyme activities and MDA levels showed tissue-specific alterations (<em>p</em><0.05). These results put forward a close relationship between AChE inhibition and chlorpyrifos concentrations. <a>In addition to</a> , CPF concentrations caused oxidative stress and inhibition in all enzyme activities of two different trout species’ gill, liver and kidney tissues.
