# Elemental Profiles of Legumes and Seeds in View of Chemometric Approach
## 3 Results and Discussion
### Correlations among Macro-, Microelements and Toxic Metals Content in Legumes and Oilseeds  
Spearman correlation analysis has shown several statistically significant correlations (\(p<0.001\), \(p<0.01\), and \(p<0.05\)) between concentrations of the elements studied in each group of the analyzed products, i.e., legumes and seeds (Table 4). There were observed both positive and negative correlations. Legumes were characterized with a greater number of such interrelationships than seeds. However, in the latter group, there were no correlations noted between K, Cu, Co, and Ni and the rest of the analyzed elements. Interestingly, Na correlated negatively with Mn (\(p<0.05\)) in seeds, whereas in the group of legumes Na did not exhibit any correlation to other elements. Moreover, negative interrelationships were observed only for seeds, i.e., between Na and Mn or Cd and Mg. Seeds were also characterized with strong positive correlations (\(p<0.001\)) between Mg and P or Zn-P. In the case of legumes majority of chemical elements exhibited positive correlations, however, the most significant (\(p<0.001\)) were noted for the following pairs of elements, i.e., Mg-Ca and

Mg-K. A positive correlation was also observed between Cu and Fe, which is similar to results presented by [PERSON] et al. [7]. However, in contrast to [PERSON] et al. [7] findings, we did not notice a correlation between Fe and Zn. Cadmium correlated positively with P and Zn in legumes and Ca in seeds while negatively with Mg. However, according to [PERSON] et al. [31], as well as [PERSON] et al. [22] P is known to decrease to phytoavailability of Ca, Cu, Fe, and Zn. [PERSON] et al. [22] found that concentrations of metals in legumes decrease with increasing P levels. Nevertheless, N fertilizers usage resulted in a significant increase of metals levels relative to control and other P treatments [22]. Moreover, the chemical similarity of Cd and Zn results in their interaction in soil-plant systems which influence their bioavailability to plants [22; 32]. Correlations between P, Mg, K, and Ca in plants, according to [PERSON] [33], seem to be based on biochemical similarities between these elements in cell metabolism.
