The influence of heavy metals content in irrigation waters and irrigated soils on the quality of plant products was studied. In samples of irrigation water, irrigated soil and vegetables (tomato), the content of Cu, Zn, Co, Ni, Pb, Cd, Fe, Mn was determined. The studies were carried out in regions with different levels of technogenic loading. At a minimum technogenic loading, the heavy metals content in water and soil was estimated as background. The heavy metal contamination wasn't found in the water-soil-plant system. With local pollution, the Pb content in water and soil exceeds the background by 3-5 times, in vegetables it exceeds the Maximum allowable concentrations (MAC). With regional pollution (industrial zone, Donbas), the content of Cd, Co, Pb in water and soil exceeds the background by 3- 12 times, the content of Cd, Pb exceeds the MAC in vegetables. At significant technogenic loading irrigation intensifies the hazard of pollutants to accumulate in vegetables and poses serious risks to public health and the environment. The control of heavy metals content in the water-soil-plant system is necessary for ecologically safe agriculture.
