Pollution with heavy metals of mushrooms and animals living in reclaimed territories of coal dumps of Kuzbass

The return of coal mining sites to the forest fund in Kuzbass is solved through forest reclamation, usually using Scots pine Pinus sylvestris L. and silver birch Betula pendula Roth, much less often, Siberian pine Pinus sibirica Du Tour, sea buckthorn Hippophae rhamnoides L. and various willows Salix L. Studies have shown that areas reclaimed 30– 40 years ago are regularly used by the local population as recreation areas. In coniferous and deciduous forests, as well as sea buckthorn thickets formed on the site of dumps of coal mines, the local population collects hat mushrooms and conducts amateur hunting for game birds. Fruiting bodies of fungi of the class Agaricomycetes Agaricomycetes, as well as black grouse Lyrurus tetrix (Linnaeus, 1758) were selected on reclaimed dumps of coal enterprises in the Kemerovo and Novokuznetsk administrative districts of the Kemerovo region-Kuzbass. Their analysis for the presence of Hg, Cd, Cu, As and Pb did not reveal an excess of the norms established for food products. However, in most cases, the concentration of heavy metals in samples collected from remediated dumps is higher than in samples from control undisturbed areas. To assess the cumulative effect on heavy metals, small mammals-insectivores and rodents were studied. An increase in the concentrations of toxic elements, especially cadmium and mercury, is observed in the tissues of insectivorous mammals.
