Summary: Peculiarities of Cd, Zn and Cu accumulation in wheat and barley grain depending on their vegetation period have
been studied. A certain influence of the vegetation period of cereals (winter, spring) in the natural and climatic
conditions of the right-bank Forest-Steppe of Ukraine on the intensity of accumulation of heavy metals in grain has
been established. In particular, it was found that in the grain of winter wheat and barley there is a lower
concentration, accumulation coefficient, risk factor Cd, Zn and Cu compared to similar spring cereals. Some
exceedances of the admissible norm of Cd according to GOST (national standart of Ukraine) 26932 in grain of
spring wheat and barley are revealed. The concentration of Zn and Cu in the grain of both winter and spring wheat
and barley was lower than the norm compared to the maximum allowable norm (GOST 26932). The grain of winter
cereals of wheat and barley was characterized by a lower coefficient of accumulation of heavy metals, and a
relatively higher coefficient of accumulation of spring cereals. The risk factor Cd exceeded the normative limit of
1.0 only in grain of spring wheat and barley. Exceedances of the normative indicator (hazard coefficient 1.0) of Zn
and Cu in wheat and barley grain of both winter and spring crops were not observed.
