Sažetak
The bark pH-values of deciduous trees were measured on the localities with different degrees of air pollution, i.e. S02 immission, in the regions of Zagreb and Sisak. In both cities Quercus robur and Tilia cordata were investigated, while Acer platanoides and A. pseudoplatanus were examined in Zagreb and Tilia tomentosa, Betula pendula and Populus italica only in Sisak.
Lower bark pH-values were measured on the localities with greater air pollution, i.e. SO2 immission, and higher values were shown by specimens of the same species growing on comparatively less polluted localities.
These data are in accordance with those obtained in some other areas of Europe (Sweden, Poland, FR Germany), confirming that bark pH-values could be used as indicators of SO2 immission.
