Comparison of Pb concentration in the ovarian tissue of female Prussian carp during 12 months of dietary exposure to lead and 12 months of depuration. No significant differences between the groups after 3, 6, and 12 months of depuration, and a significant decrease (p < 0.01) (star) in concentration after 3-month depuration compared to the 12th month of accumulation was found in the 13-, 24-, and 49-mg Pb kg⁻¹-dep groups (Mann–Whitney test).
