【 摘 要 】

The identification of tree species used in urban areas as ornamental trees, that have particular behaviour against different heavy metal pollution is of great importance. The aim of our study was to identify the biomonitoring capacity of five tree species used in a heavy traffic area of Cluj - Napoca, Aurel Vlaicu street, by quantification of foliar bioaccumulation of Cu, Cd, Pb and Zn. In the present paper are emphasized and discussed the results obtained in 2010. The leaves were collected weekly from five tree species: Pinus nigra, Aesculus hippocastanum, Betula pendula, Picea pungens var. glauca and Tilia cordata, and heavy metals quantified in the Laboratories of the Department of Environmental and Plant Protection from the Faculty of Agriculture of the UASVM Cluj - Napoca, with Perkin - Elmer  Atomic Absorption Spectrometer with flame and graphite furnace, Analyst 800. All analyzed trees have the biggest accumulation capacity for zinc, meaning that all can be used as biomonitoring agents for this element. is Aescullum hippocastanum is the most suitable biomonitoring agent for lead and copper pollution while, Betula pendula have the biggest bioaccumulation capacity for cadmium.
