Changes of Pb concentration in the kidney, gills, hepatopancreas, and muscle of Prussian carp females during 12 months dietary exposure to that metal and following 12 months depuration periods. Significant differences of lead concentration between groups (uppercase letters) and in dependence on time depuration (lowercase letters). Different letters mean significant difference p < 0.05. There were no significant differences in muscle tissue. Note the different y-axis scale
