Abstract
A comparison of the functional state of goby fish caught at the ecological monitoring station in the locations of oil-producing wells is carried out. The results of the assessment of the antioxidant system and the processes of lipid peroxidation of aquatic organisms are presented. Biochemical markers are used in biomonitoring studies to analyze the toxicity of polluting factors in the aquatic environment. Low indices of malondialdehyde content in fish liver from 1.1 to 9.6 nmol were found at three studied stations. A significant increase in the content of the product of lipid peroxidation in the liver and muscle tissue of fish was revealed at certain stations in the Northern Caspian. In general, indicators that exceed the conditional norm for the accumulation of MDA in the liver and muscle tissue of aquatic organisms were noted at 5 out of 31 studied stations. The data obtained indicate the development of oxidative stress and the enhancement of the protective properties of the fish organism under conditions of high anthropogenic load.
