Content of mercury in organs and tissues of the Caspian seal (Phoca caspica Gmelin, 1788)
The aim of this study was to determine the level of mercury accumulation in organs and tissues of the Caspian seal of different ages. The determination of mercury in the organs and tissues of seals has been performed on RA -915 atomic absorption spectrometer with RP-91S station. Comparative analysis of the concentrations of mercury in organs of different aged Caspian seals has shown similarities in their distribution. Mercury concentrations in the liver and kidneys are higher than in other organs. The level of mercury accumulation in the liver exceeded the maximum permissible concentration (MPC) in each age group, increasing with age…
