Abstract
The work shows how the average content of elements changes under the impact of motor transport with an increase in the intensity of their movement. For this, the concentration clarkes (coefficients) proposed by V. I. Vernadsky are used. The accumulation of elements is considered using indices of absolute (IAA) and relative (IRA) accumulation (IAA is expressed in t/km2). This makes it possible to plan the improvement of the ecological and geochemical situation in the recreational and tourist centers (RTC) of the Black Sea coast. The IAA values relative to the clarke of soils reach 300 t/km2 (Sr in the soils of the Massandra settlement in comparison with the clarke content in soils). Most often, in the soils of the RTC of the Black Sea coast, in addition to Sr the contents of Cu, Zn and, somewhat less often, of Li and V are also increased. It was found that the following elements, the increased content of which are associated with the movement of vehicles, had the greatest influence on the current ecological and geochemical state of the soils of the RTC of the Black Sea coast and on the conditions for the development of living matter in them: Cu> Zn> Sr> Li.
