Abstract: Juniperus communis L. is one out of three naturally growing conifer species of Lithuania. This conifer is characterized as valuable species for medicine, pharmacology, culinary or ornamental purposes. Processes of secondary metabolite formation and changes in some vital functions of the plants could be influenced by concentration of non-essential elements. Concentration of heavy metals in the needles of common juniper sampled near industrial pollution sources have been documented [1], but information about these element concentrations depending on habitat type is still missing. J. communis is widely spread in non-polluted areas of Lithuania, so it could be useful indicator of areas with elevated level of contamination. In our study plant material was collected from 14 populations (140 juniper individuals) from different geographic regions of Lithuania distributed in 5 habitat types. Elements (Cr, Ni, Cd, Pb) from J. communis needles were analysed using atomic absorption spectrometry. Our results showed that mean (per population) concentration of Cr ranged from 0.238 to 0.531 μg/g dry mass (d. m.), Ni – 0.180–1.520 μg/g d. m., Cd – 0.004–0.105 μg/g d. m., Pb – 0.126–0.537 μg/g d. m. The highest concentration of Cr and Cd was found in coastal brown dunes covered with natural Scots pine forest in Curonian spit. The lowest concentration of Cr was found in xero-thermophile fringe near Kaunas. The highest concentration of Ni was found in subcontinental moss Scots pine forest besides Kelme, while the lowest concentration was characteristic for transition mires quaking bog of Ignalina. The lowest concentration of Cd was common for xero-thermophile fringe in Jurbarkas. The highest Pb was found in transition mires quaking bog site near Kelme, the lowest – subcontinental moss Scots pine forest in Ignalina district. [...]
