Abstract—: The purpose of this review is to systematize data on the level of soil pollution and the rate of erosion processes in the Republic of Kazakhstan (RK) and to identify river basins with the high probability of secondary soil pollution due to the lateral migration of pollutants transported together with sediments. Using the Google Scholar, Springer Link, Science Direct, Scopus, and RSCI search engines, publications on soil pollution with heavy metals (HMs), radionuclides of technogenic and natural origins, oil and petroleum products, and rocket fuel components, as well as characterizing the rates of water and wind erosion and the degree of soil erosion in the RK were collected. On the basis of these data, thematic maps of the RK showing river basins with increased concentrations of pollutants in soils were compiled. Using the maps of soil pollution and water and wind erosion, river basins with the high probability of secondary soil pollution due to the transport of contaminated soil particles by water-erosion processes and local transport by wind were identified. It was found that the most intense secondary pollution, primarily of alluvial soils, can occur in the basins of the Irtysh and Shu rivers. It should be taken into account that existing estimates of water erosion rates are based on calculations using erosion models, while estimates of wind erosion rates are based on semiquantitative data. In this regard, research is needed to verify calculations using erosion models based on field data.
