The long-term development of tin deposits in the Komsomolsk region by the Solnechny GOK and Processing Plant has led to a significant increase in pollution of environmental components. The results of the study show that the environmental condition within the boundaries of this tin producer is critical. The above studies discuss the mobile forms of zinc, chromium, lead, copper, mercury, arsenic, antimony compounds in the upper horizons of soils. Chromium, arsenic and antimony compounds make the maximum contribution to pollution and, accordingly, the amount of damage to the soil, since the excess content for these elements and their compounds in relation to background values is maximum. The necessity of creating an environmental monitoring center in the research area is discussed. The data of mining and environmental monitoring make it possible to calculate the amount of damage caused to environmental objects in value terms and justify methods of reclamation of disturbed lands.
