Abstract
Abstract The parameters of migration models of Cr, Ni, Cu, Pb, F in the soils of the Eastern Orenburg technogenic biogeochemical province are estimated. The enterprises of ferrous metallurgy, non-ferrous metallurgy, chemical industry are concentrated in this region, and there are many-year soil pollution. The results of field surveys of the 1980 s. Diffusion and convection-diffusion models were used. These models met the criteria of adequacy in most cases. The values of the diffusion parameters found are compared with the previously published values. The “apparent” diffusion coefficients are in the range (0.2-27) 10-8 cm2 /s. Soil contamination forecast for 2020 is calculated. Calculated forecast values can be compared with the results of the next monitoring survey.
