Abstract

A geochemical survey of lead contamination was conducted for soils of the Republic of Tatarstan. 1164 topsoil samples were collected from different soil types. The effect of land use type (natural, agricultural, urbanized) on lead content and mobility in the topsoil was evaluated. The method of regression trees was used to study the structure of interactions between lead and other soil factors (organic matter, physical clay, Fe, Mn, pH). The relative impacts of soil constituents on the content and mobility of lead in soils were assessed. The results showed that human activities were not the primary source of lead in the soils under natural and agricultural land use types. The correlations between content and mobility of lead and soil components are determined by the soil type and land use type
