Abstract

The article discusses the influence of toxic elements in muscles on the activities of antioxidant enzymes and oxidative modification of serum blood proteins in round goby (Neogobius melanostomus) collected from coastal area of the Black Sea (Sevastopol). The obtained results showed that the most sensitive to tissue accumulation of elements are enzymes SOD and PER, while Pb and Hg have the most toxic effect on the organism as a result of linking with the functional groups of biomolecules. The activities of antioxidant enzymes and oxidative modification of serum blood proteins can be used for evaluation of fish status and water quality. Refs 26. Tables 7.
