Heavy metal-іnduced oxidative stress and changes in physiological process of free radicals in the blood of white stork (Ciconia ciconia) chicks in polluted areas

Abstract

The aim of this study was to examine the impact of Ca, Mg, Fe, Na, k, zn, Cd, and Pb upon enzymatic activity of superoxide dismutase (Sod), catalase (CAT), and ceruloplasmine (CP) diurnal and nocturnal activity, and the content of thiobarbituric acid-reactive substances (TBARS), and their interaction with free radicals, in the blood of the White Stork (Ciconia ciconia), an altricial bird, during postnatal development, in polluted areas (copper manufacture) and in control environments. The age of chicks examined from an output from an egg was increased from 19 to 54 days. Samples of investigated wing venous blood were taken for AAS analyses of element concentration. We collected blood samples via veni-puncture of the brachial vein of chicks.
