Аннотация: Significant environmental impacts of mining activities connected with high-sulfur materials result from the production of acid mine drainage and potentially toxic elements that easily migrate to adjacent ecosystems due to the typical absence of vegetation on spoil heaps and toeslope talus mantle. In this paper, we present the results of the first comprehensive study of the ecosystems affected by acidic and metal-enriched (Al, Ca, Co, Cu, Fe, Mg, Mn, Ni and Zn) mine drainage conducted at spoil heaps and adjacent talus mantle under semihumid climate conditions within the Moscow Brown Coal Basin (Central Russian Upland, Tula Region, Russia). A total of 162 samples were collected including 98 soil, 42 surface water and 22 plant (aerial tissues of birch) samples. Coal talus mantle materials of Regosols were characterized by the increased concentration of wa-ter-soluble Ca, K, Mg and S and all mobile fractions of Al, Co, S and Zn. The chemical composition of birch samples within the zones affected by acid mine drainage insignificantly differed from that in the unpolluted ecosystems with black soils due to the high tolerance of birch to such conditions. Differences between the studied affected and undisturbed sites in terms of the chemical composition decreased in the following order: waters > soils > plants. The geochemical characterization of plants and soils in coal mining areas is essential for the mitigation of negative consequences of mining activities.
