SUMMARY: Air pollution has a great impact on the damage and the vitality decrease of fir trees (Abies alba Mill.). The damage of fir trees is largely visible in Gorski Kotar in the Risnjak National Park. More than 50 % of trees have significant crown damage. Their decline is connected with air pollution and the heavy metal elements found in the forest ground. The research on fir damage was carried out through structure analysis of the tannins in the cells of fir needles, in reference to the quantity of the microelements in the needles, and as to the kind and quantity of microelements in bee honey. The research included one-year-old fir tree needles (Abies alba Mill.), which were collected in natural conditions in the years 2000 and 2001 on two locations. The first was Risnjak, which represented a polluted site of experimental type. The second was Donja Dobra, representing a clean site of a control or reference type. The needles were collected from the trees with various stage of damage, during three periods of time: May, July, and September of each sample year. On the Risnjak site, the needles were collected from the crowns with significant damage. This means that these trees had over 20 % of needle loss. The trees with crown damage of 35 %, 45 %, 55 %, 75 % and 85 % were chosen on this site. The needles from the trees with slightly damaged crowns, between 5 % and 10 %, were collected on the site of Donja Dobra. The needles used for the analysis of microelements were collected from the trees on both locations. Bee honey, in this case honeydew honey, was collected at the end of vegetation season from the beehives near the location where the needles were collected. The needles were moulded in paraffin wax and coloured using a special technique. The appearance of tannin, the shape and spreading, as well as the cell structure were analysed using a light microscope. The analysis of the microelements in the needles was carried out for ten elements (Ca, Fe, Rb, Sr, Cu, Zn, Pb, Ni, Mn and Cr), the concentrations of which were determined by X-ray fluorescence using energetic dispersion, Energy Dispersive X-Ray Fluorescence, and the EDXRF method. The bee an honey was analysed by the same method.In In addition, the contents of radionu |
