The dynamics of cadmium elimination were assessed in various organs (liver, kidneys, skin, gills, alimentary tract, muscles) of freshwater common carp, Cyprinus carpio L. The fish used in the study were undergoing a period of intensive growth between the third and sixth months of life. Comparatively cadmium elimination dynamics by various organs of common carp after transferring them to a laboratory environment, taking into account their growth rate and accompanying seasonal changes was assessed. The study focused on individuals of common carp obtained from an experimental station where they had been kept in post-cooling water. Average cadmium contents in the examined carp organs ranged from 0.004 to 0.053 mg/g wet weight. The highest values of Cd content were recorded in the liver, the mid posterior section of the alimentary tract, and the gills, while the lowest value was noted in the muscles
