Rezumat: The research goal was studying seasonal variations in the contents of heavy metals in leaves of Platanus orientalis in Yerevan. Assessment of condition of the selected tree specimens was also included in the study. Leaf sampling was done in May and September 2015. Pb, Hg, Ni, Mo, Cu, Zn concentrations in pretreated samples were measured by the accepted atomic absorption method. As indicated, concentrations of Pb, Hg, Mo are higher in the end of vegetation period. Besides, the leaves of studied Platanus orientalis sampled from Yerevan’s southern, southwest and central districts are also high in Hg, Ni, Mo.
