Sažetak
Vegetation is a useful indicator of environmental (heavy) metal contamination via root uptake as well as via precipitation on the outer surface. This fact can be used to monitor pollution across both spatial and temporal scales. Pine needles are considered to be good biomonitors of air pollutants due to their waxy surfaces, which accumulate not only gaseous pollutants, but also polluting particulates. The accumulation behaviour depends on the one hand on the present pollution situation and on the other hand on the species. Especially in areas with known high contamination of certain metals, the growth of special accumulators can reduce the impact on the surrounding environment. Thus the influence of hybridization of pines on the metal accumulation is of interest for environmental reasons. The present study focuses on the determination of Al, As, B, Ba, Ca, Cd, Co, Cu, Cr, Fe, K, Li, Mg, Mn, Mo, Na, Ni, Pb, Se, Sr, and Zn in needles of Pinus nigra and Pinus thunbergiana as well as of their hybrids. The elemental concentrations were determined by ICP-AES and ICP-MS after acidic microwave assisted digestion. Regarding differences in accumulation of metals in the needles, the hybrids show higher amounts of Al, Cd, Mn, Ni, Mg, Mn, and Zn than parent pine species. For the majority of the metals investigated, the accumulation behaviour is dominantly influenced by the mother.
