establishment of objective regional background landscape geochemical parameters,
based on scientifically proven indicators of the MPC.
To determine the quality and condition of soils, as well as the degree of
accumulation of heavy metals, we calculate the coefficient of concentration (Kc),
which is characterized by the ratio of the content of the chemical element in the soil to
its background value [11].

The calculation of the coefficient of concentration of trace elements in soils is
calculated by the formula (Table 3):
К
с
= С
i
/Ф
і
where С
i
– the content of a chemical element in a particular object, mg / kg; Ф
і
–
the background content of the chemical element in the soil, mg/kg (Table 2).

In order to assess the environmental situation, the indicator of the pollution
intensities of the natural component Rj and the integral index of environmental hazard
of the landscape I
нб
are also used. These indicators are important in assessing the
ecological and geochemical conditions of the populated areas because they are
complex and characterize pollution of soil, atmosphere, water and all other elements.
