Annotation:  The article presents the analysis of concentrations of gross, mobile and water-soluble forms of heavy metals (HM): copper, zinc and nickel in light chestnut soils (kastanozems) of petrol stations of different granulometric composition and alluvial soils (fluviosoils) of the river port of agglomeration Volgograd-Volzhsky (the River port). In light chestnut clay soil of petrol station number 1 was discovered the maximum content of mobile form Ni and water-soluble form Cu. The highest concentrations of all forms of Zn, mobile form Cu and the lowest concentration of water-soluble form Cu are revealed in light chestnut sandy soil petrol station number 3. In alluvial soil of the River port was found the maximum concentrations of gross forms Cu and Ni and the minimum concentrations of all forms Zn and mobile forms Cu and Ni. The content of water-soluble Ni forms in soils of all objects is the same and does not depend on the type of soil, granulometric composition and total accumulation of the element. The main factor in the accumulation of heavy metals is technogenesis, which often "overlaps" the influence of natural factors of soil formation, but depends on the degree of anthropogenic load and chemical properties of the elements themselves. The values of heavy metals obtained from the experimental studies can be used for soil monitoring and development of measures to reduce negative impacts on the environment.

Keywords:  heavy metals (HM), total, mobile and water-soluble form, light chestnut soil (kastanozems), alluvial soil (fluviosoils), the accumulation, maximum permissible concentration (MPC), deportment
