ABSTRACT. The purpose of study was an investigation of the impact of high soil selenium (Se) on iron (Fe), copper (Cu), zinc (Zn), and manganese (Mn) in grain and flour from wheat, rice and maize. Determination of trace elements level was performed using mass spectroscopy with inductively coupled plasma after microwave digestion. It was established that cultivation on seleniferous soils results in an increase of Se accumulation in grain and wheat, rice and maize flourby a factor of 106 and 45, 107 and 80, and also 458 and 269, compared to control values, relatively. Selenium exposure is accompanied by significant elevation of Cu, Mn, and Fe accumulation in wheat grain samples by 41%, 48%, and 211%, whereas similar increase in flour was estimated to be 33%, 40%, and 97% respectively. In contrast to wheat, copper level in rice grain and powder with high selenium level was lower than the control values by 45% and 30%, respectively. Maize cultivation on the seleniferoussoils lead to significant decrease of copper level in maize grain by 41% while, zinc level was characterized by a more than 2-fold increase. At the same time, Cu, Fe, and Mn level in high selenium maize flour was nearly 3-fold lower than respective control values. Therefore, wheat grown on selenium-rich soils may be considered as an additional source of other essential elements, whereas their intake with selenium rich maize and its foods could be insufficient.
