INTENSITY OF HEAVY METAL POLLUTION OF NATURAL SOILS OF NATURAL FORAGE BOWLS IN THE CONDITIONS OF VINNITSA REGION

Abstract

The article is devoted to the research of the influence of man-made load on the soils of natural forage lands. The peculiarities of the accumulation of heavy metals in plant biodiversity under different man-made loads on natural forage lands have not been sufficiently studied. The priority of such goals is caused by the social factor of reducing the technogenic impact on the population by preventing the transformation of contaminants of pollution in plant feed materials. The studied natural forage lands are characterized by uneven relief, high waterlogging in the lowlands, large slopes and low productivity, which are not always attractive and economically viable for their restoration. However, they are a powerful source of cheap plant raw materials for livestock, especially for individual use. The use of weeds of natural fodder meadows contaminated with heavy metals leads to an increase in their accumulation in livestock products, in particular, in milk, meat and other products. The article highlights the intensity of heavy metal contamination of soils of natural fodder meadows of Vinnytsya region. Today, in the conditions of technogenesis, natural forage lands are subjected to a strong anthropogenic load in some areas, which leads to soil contamination by various toxicants, in particular, heavy metals such as Pb, Сd, Zn and Cu. The given data in the article illuminates the results of studying the intensity of soil contamination and phytomas of natural fodder lands in conditions of absolute landsols, normal land drainages and excessive moisturizing agents for total background contamination. It was found that the highest concentration of heavy metals was characterized by soils of excessive moisturizing lands, but exceeds the MPC by lead, cadmium, zinc and copper are not detected. It has been established that the lowest content of heavy metals was found in the soils of absolute landsols. However, the concentration of heavy metals in phytomass did not exceed the MPC. The priority of research on the intensity of pollution of plant biodiversity is also caused by a social factor, namely the reduction of man-made impact on the population by preventing the transformation of contaminants in plant feed materials "soil - plants - crop products - human body".
