Such contamination is closely linked to threats to human health, as the bioavailability of these elements allows their transfer from crops into the food chain. The aim of the study is to assess the bioavailability of selected elements in barley grain in case of possible soil contamination with selected selected elements. The main novelty of the work consists in the evaluation of the mutual correlation of selected elementss in the bioavailability of spring barley with respect to different treatments. To determine the selected elements bioavailability, the content of selected selected elements was monitored in soil with the addition of NPK and in soil treated with the addition of Mo, Sr, As, Cd. To evaluate the accessibility of selected elements, or their synergism, we used selected methods of inductive statistics. The α-level of 0.05 was set as the decision rule in all statistical tests. Based on our analysis at the unit change of Mo, Mn in spring barley grain increases by an average of 2.14 mg.kg− 1 when grown in strontium-enriched soil. According to our study, barley grain at a unit change of As increases by an average in Mn content by 24.44 mg.kg− 1 with the addition of Cd. According to our results, the addition of Mo to the soil caused an average decrease in Zn at the unit change of As by 3.4 mg.kg− 1. Likewise, an average increase in Mo of 38.45 mg.kg− 1 at the unit change of As (addition of Mo) was confirmed. A negative correlation was confirmed between pairs of elements Mo and Zn without the addition of selected elements. The study confirmed statistically significant differences in the content of selected elements in individual treatments compared to the control NPK sample. At the same time, a positive or negative correlation in the bioavailability of selected selected elements was confirmed.enCC BY-NC-ND Creative Commons Attribution-NonCommercial-NoDerivatives 4.0.
