Abstract
The forms of zinc compounds under the polyelement and zinc kinds of pollution of light- and dark-chestnut soil are studied. It is established that the initial relations between the element forms changes under any kind of pollution. Zinc accumulation in the most mobile forms with an increase in soil pollution was detected for both kinds of pollution. In the case of the polyelement soil pollution, the mobility of the element is much higher than that in the case of the monoelement pollution. Different capacities of the soil kinds under investigation to zinc fixation were determined. It was revealed that the basic mechanism of zinc fixation in polluted soil is ion exchange absorption.
