Heavy Metal Accumulation In Bark Some Woody Plants

Fast technological and industrial development in the last two decades has caused accumulation of harmful matters in the air, water and on soil which nowadays have negative impact on climate and consequently on eco systems. In this paper we have presented the results of determination heavy metal in six plant species. Three plants belong to evergreen plants (Nerium oleander, Viburnum tinus, Pyracantha coccinea) and other three to deciduous plants (Celtis australis, Ficus carica, Sophora japonica). Each plant investigated in this study accumulated the four heavy metals: Zn, Cu, Pb and Cd. The concentrations of these metals were measured by AAS and UV/VIS spectrophotometry. The highest concentrations of metals, exspecially Zn and Pb were found for Viburnum tinus and Pyracantha coccinea while the lowest concentrations of all metals were found for Celtis australis. It was noted that metals concentrations were in corelatin with traffic.
