Abstract
Bioaccumulation of mercury in the food chain can pose a threat to human health. Therefore, in our article, we obtained data on the concentrations of mercury in the tissues of wild animals, which are a food resource for humans. We determined the mercury concentrations in liver, kidneys, muscles and hair of wild boar and moose, which are consumed by the population of the Russky Sever National Park. The average mercury concentrations in moose tissues ranged from 0.004 mg / kg wet weight in muscles to 0.079 mg / kg wet weight in kidneys. The average concentrations of mercury in boar tissues ranged from 0.136 mg / kg wet weight in wool to 0.711 mg / kg wet weight in kidneys. The main trends of mercury bioaccumulation in the tissues of moose and wild boar were determined.
Highlights
Mercury (Hg) is a global toxic pollutant that tends to bioaccumulate and biomagnify in the food chain [1, 2, 3, 4]

Summary
Mercury (Hg) is a global toxic pollutant that tends to bioaccumulate and biomagnify in the food chain [1, 2, 3, 4]. The toxic properties of mercury make it a serious threat to the environment and living organisms [5]. Local residents traditionally eat wild boar and moose meat, so the presence of potentially toxic elements, such as mercury, can lead to increased impact consumers of these animals ' organs. It is important to assess the mercury concentrations in the tissues of these species of commercial mammals of the Russky Sever National Park, as well as to check possible trends of the bioaccumulation of this toxic metal in their tissues
