The aim of the study was to determine the influence of cadmium sub-lethal intoxication doses (10 µg Cd · kg-1 body weight) on zinc levels in freshwater fish tissues, using the common carp as the experimental example. The 60-day experiment was divided into 8 stages during which organs and tissues were collected (liver, kidneys, skin, gills, alimentary tract and muscles). Zinc levels were determined in the collected samples at designated time periods. Statistically important changes in zinc concentrations were obtained. The performed experiment facilitated obtaining images of zinc level changes in cadmium poisoned carps during the detoxification process.
