ASSESSMENT OF SOIL CONTAMINATION IN ISTRA

Abstract

The paper reviews the spatial distribution of zinc (Zn), lead (Pb), cadmium (Cd), nickel (Ni), and copper (Cu) in soil. The study was performed in the city of Istra. The common samples of soil were selected within the limits of the city. It is found that almost in all examined areas the content of heavy metals in soil belongs to the category of permissible contamination except for the areas adjacent to the industrial enterprises. The first-priority soil pollutants are Pb and Cd, the release of which is mainly associated with the motor vehicles.
