Abstract: | The content of natural (S, N, P, Ca, Mg, K, Mn, Zn, Cu) and extraneous elements (Pb, Cd, Al) in leaves of birch growing in
the Krusne hory Mts. (Czech Republic), a territory affected by air pollution (SO2), was evaluated with regard to the altitude and age of birch stands, and in relation to stand nutrition. The contents of
S, Ca, Mg, Zn and Pb culminated at the highest points of the altitudinal transect (elevation 900–1000 m). In contrast, at
high altitudes the content of Cd, Al and Mn decreased. The content of elements in leaves was mostly not dependent on tree
age. In terms of nutrition and growth of birch, the content of Cu was insufficient, the content of Ca, Mg, N, P and K was
optimum, and the content of S, Zn and primarily Mn was higher. The content of Pb and Al was at natural background levels,
that of Cd higher.
