Abstract
The content of such typical ecologically hazardous chemical elements as Pb, Ni, Cu, Sr, and Zn in soil and plant ash from the vicinity of an industrial center is measured. Since the main sources of these elements are smoke aerosols of industrial origin, the dependence of the concentrations of these elements on the distance from highly profuse, continually operating sources of emission is measured to a distance of ∼10 km. It is shown that the laws governing the variation of the concentration of different chemical elements in soil with the distance from the source of emission into the atmosphere are determined by the conditions of their gravity settling with consideration of the electrical interaction of the aerosol with the ground electric field and that the laws in plant ash are determined by the accumulation of highly dispersed, charged aerosol on the surface of plant leaves polarized in the ground electric field.
