The paper deals with the soil pollution by heavy metals as a consequence of anthropogenic activities in Zolochiv Rayon, Lviv Oblast. Chemical and physical properties of the elements are considered as well as their impact on the population’s health. Considerable attention is given to the distribution of the heavy metals according to soil types, land forms and hydrological regimes. Key words: heavy metals, copper, nickel, magnum, chrome.
