Biochemical parameters of blood as the markers of oxidative stress development in organism of annotinous carp (Cyprinus carpio L.) in conditions of water medium intoxication by lead ions

Influence of a chronic intoxication by lead ions on biochemical parameters of annotinous carp blood (the maintenance of the common protein, albumin, bilirubin, urea, malonic dialdehyde, activity of catalase, alanin- and aspartataminotranspherase and the common antioxidant activity of blood plasma) is studied. The data testifying the development of oxidizing stress in aquatic organisms that is important for an es-timation of state of their health and monitoring fishery reservoirs are obtained.
