ABSTRACT. The activities of the mining industry in the regions of the Trans-Urals of the Republic of Bashkortostan contributed to the rapid development of enterprises. As a result, contamination of natural environments with technogenic emissions from rocky heaps of quarries of pyrite ores is applied to the background contamination of soils with heavy metals. Polymetallic contamination is affected by soils of individual and collective orchards and vegetable gardens adjacent to quarries, the Sibay concentrator and the tailings pond. The features of the distribution of the gross and mobile forms of Cu, Zn, Cd, Mn and Pb in the soils of the gardens and cities of Sibay are investigated. As a result, high concentrations of elements in soils in the areas adjacent to the dumps of the "Sibay" and "Kamagan" quarries and in the vicinity of the Sibay concentrator were identified. Soils contain an elevated level of Cu, Zn, in some cases - Cd, Mn and Pb. The greatest contamination is affected by soils and potato tubers growing in them in the districts of the city of "Zoloto", "Gorny", "Yuzhny" and the collective garden No. 10. The high content of Zn (more than 10 mg/kg) was observed in potato tubers grown on all test sites. Potato tubers grown in the districts of the city "Zoloto" and "Gornyi" also showed high concentrations of Cd. This fact requires increased attention to the products produced in the city. To improve the trace element composition and improve the quality of plant products, rational use of zeolites, organic fertilizers, liming is necessary.
