Abstract
As a result of the effect of various factors on aquatic ecosystems, polluting agents such as many heavy metals are mixed, and as a result, the living creatures in the aquatic ecosystem are adversely affected because of contamination with these chemical agents. In recent years, it is important to monitor living organisms and their metabolic processes to determine the cleanliness of water. Therefore, in our study, malondialdehyde (MDA), glutathione (GSH), and Total Antioxidant Status (TAS) which is an oxidative stress marker in the gills, liver, and lungs of Cyprinus Carpio L., which is widely found in the Obruk Dam Lake in Oğuzlar district of Çorum province? A total of 90 Cyprinus carpio specimens were collected from different parts of the Obruk Dam Lake. Relevant tissues of the samples were taken and homogenized. Methods suitable for spectrophotometric measurement were used to determine MDA, GSH and TAS levels. According to the results, it was determined that antioxidant biomarkers were higher in the liver and gills. According to the data obtained from our previous studies, it is reported that the water of the Obruk Dam Lake complies with the standards in terms of heavy metals. These data showed that the physiological events that occur in the relevant tissues to provide oxidative balance contribute to the stabilization of the aquatic ecosystem.
