Background. The main reason of substantial flow of pollutants (heavy metals, etc.), entering the soil agglomeration of Volgograd-Volzhskiy is a huge amount of anthropogenic sources of environmental pollution (industrial plants, highways, gas stations, etc.). Therefore, scientific and practical interest is the monitoring of content of heavy metals (HM) of various forms in soils of various genesis in close proximity to sources of anthropogenic impact on ecosystems, required to develop efficient and environmentally friendly measures to reduce the “metal press”.
Material and methods. The samples are light brown and alluvial soils for analysis was carried out on the territory of Volzhsky of the Volgograd region (the gas station number 1 and number 3, the river port) in 2015–2017. In the samples was determined the concentration of gross, mobile, water-soluble and sorbate forms of heavy metals. The concentration of water soluble forms of TM were determined in water extracts from soils, and their sorbate forms in soil samples exposed to elevated temperature and pressure in an autoclave.
Results and conclusions. In work the comparative analysis of concentrations of gross, mobile, water-soluble and sorbate forms of heavy metals (Cu, Zn and Ni) and their percentage in relation to their gross forms. When analyzing the test data it is obvious that in soils dominated by zinc, less copper. In the soil of river port detected maximum concentrations of total forms of Cu and Ni and sorbing form of Ni and minimum concentrations of the gross forms of Zn, the mobile forms of Ni, sorbing forms of Cu and Zn. The number of TM enshrined in the minerals in all soils more than the maintenance of mobile and water-soluble. Motile fractions of HM in
3–13 times less than their total forms. Water-soluble fractions of HM 2–10 times less than moving. Fractions isolated after thermal desorption 2–4 times less than the total content of TM.
