The current pace of construction and operation of roads along the coast, increasing tourism facilities increase the burden on the environment. One of the important problems is the increase of a chemical contamination of soils. In the simulation study it is established that brown forest sour soils are least resistant to the effects of Cr, Cu, Ni, Pb and oil among the major soils of the Black Sea coast of the Caucasus. Pollution leads to a significant deterioration of their biological properties: reduced total number of bacteria, the activity of catalase and dehydrogenase, cellulolytic ability, abundance of bacteria of the genus Azotobacter, worsening indicators of germination and initial growth of radish. According to the degree of an adverse effect on biological properties of a brown forest sour soil the heavy metals form the following series: Cr> Cu= Ni>Pb.
