The actual material for the present work were the results of elemental analysis of soil samples taken in the Central part of the neighborhood Novotroitsk city Baleya, the section from the former tailings processing plant for the extraction of thorium from monazite concentrate sand through the valley of the river with waste monazite alluvial bulk to the tailings gold processing plants. The interpretation of the obtained data showed high contents of a number of elements, significantly exceeding the MPC. The total indicator of soil pollution (pollution indicator), calculated for five chemical elements (Pb, As, Sb, Ag, Th), indicates a dangerous and extremely dangerous environmental situation for public health and the need for detailed geochemical monitoring of soils. An urgent problem is also the assessment of the contribution of aerosol transport of pollutants during the transportation of sludge from gold recovery factories on the territory of the district Novotroitsk
