The research was conducted with the aim of examining the presence of toxic elements (Pb, Cd, As and Hg) and essential elements (Zn, Cu, Fe and Mn) in selected samples of wheat flour and bran by Inductively Coupled Plasma Mass Spectrometry. The principal component analysis has been used for assessing the variety of samples. Quality results show that the first two principal components, accounting for 84.22% of the total variability, can be considered sufficient for data representation and the first two principal components for toxic elements and essential microelements. Zn (16.38%), Mn (16.19%), Cu (15.73), Fe (15.44%) and Cd (14.99%) have been found the most influential for the first factor coordinate calculation, while the contribution of Hg (89.09%) has been the most important variable for the second factor coordinate calculation.
