Summary: In accordance with the principles of sustainable development, one of the most urgent tasks of today is to provide the population with a sufficient amount of high-quality and safe food of both plant and animal origin. It is known that the quality and safety of food products are directly dependent on the environmental conditions of food raw material production. Vegetation of natural fodder lands is an important element of livestock production, which is characterised by low cost compared to cultivated lands. However, in some areas, natural fodder lands undergo a strong anthropogenic load in the context of technogenesis, which leads to soil contamination with various toxicants, in particular, heavy metals such as Pb, Cd, Zn and Cu. The main sources of pollution of natural forage lands are industry, motor vehicles, chemicalisation of the crop production sector, and others. Under such conditions, the use of phytocoenoses as feedstock for both domestic and wild animals increases the risk of heavy metals entering their bodies, which threatens the production of safe and high-quality products, and contaminated soils may be withdrawn from agricultural use. The aim of the study was to determine the levels of accumulation of Pb, Cd, Zn and Cu in the ecosystems of natural forage lands under different anthropogenic load in the conditions of Eastern Podillia in Vinnytsia region. The intensity of accumulation of Pb, Cd, Zn and Cu by plants of absolute drylands, normal drylands and drylands of excessive moisture in the lowland dry meadows of Vinnytsia region under conditions of different technogenic load was assessed. The excess of heavy metals in the phytomass of cadmium alone was found to be 1.01 times higher in the areas of excessive moisture adjacent to the railway; - the tendency of the phytomass of excessively moist lands to higher accumulation of heavy metals, which can exceed the MPC by 1.18 times for lead and 1.1 times for cadmium (compared to meadow ecosystems of absolute and normal lands) and acquire the category of technogenically contaminated lands, was revealed. Prediction of the intensity of Pb, Cd, Zn and Cu intake into plants of natural fodder lands under conditions of anthropogenic load was improved based on the study of their accumulation coefficients. As a result of theoretical analysis and field and laboratory experiments, the intensity of Pb, Cd, Zn and Cu accumulation in phytocoenoses of dry lowland meadows of natural fodder lands under different anthropogenic pollution was studied.
