Abstract
Forms of zinc compounds in light-chestnut soil under pollution with zinc, copper, cadmium, lead introduced separately and jointly were studied. It was discovered that for any kinds of pollution the initial relations between the forms of an element change. With an increase in the level of pollution, for all its kinds, accumulation of the most mobile forms of zinc in the soil is observed. It was revealed that ion exchange has the highest significance in the fixation of zinc in polluted soil.
