The radial patterns of 13 elements (N, P, K, Ca, Mg, Fe, Na, Mn, Zn, Cu, Pb, Cd and Co) were analyzed in the tree rings of European beech (Fagus sylvatica L.). The study site was located in an "unpolluted" beech ecosystem in Mavrovo National Park. Thus, the obtained radial patterns in the beech trees were considered to be physiologically driven without significant pollution influence. The influence of the main climatic factors (temperature and rainfall) was tested. The radial patterns of

For most of the elements, higher concentrations were recorded in the pith and outer-most rings and lower in the middle part of the wood. The concentration of heavy metals was low, and followed the physiological patterns of other biogenic elements.
