CHANGES IN THE MOBILITY OF HEAVY METALS IN GRAY MEADOW SOILS DEPENDING ON THE DEGREE OF THEIR HUMUS CONTENT AND THE USE OF HIGH DOSES OF ORGANIC FERTILIZERS

Abstract

Currently, the problem of soil pollution with heavy metals in technogenic and agricultural industries is acute. Heavy metals occupy one of the leading places among environmental pollutants. Many representatives of this group of substances, such as lead, copper, zinc, cadmium, even in very small quantities, can cause immunological, oncological and other types of diseases. As a result of studies conducted by scientists from different countries, it has been proven that about 70 percent of heavy metals enter the human body with food.
