In the study the environmental problems con-nected with the content of heavy metals in leaves and needles of tree species are discussed: birches, fir-trees and poplars in the squares and parks of the right bank of Krasnoyarsk. It was established that the high level of atmospheric pollution caused by technogenic loadings led to deterioration of natural objects, such as the soil and plants. Big danger to vegetable community was constituted by heavy metals. Heavy metals, collecting in vitals of plants, led to oppression of the metabolism, slowing down the growth and development, and in other cases to death of the crops. It was revealed that various va-rieties of arboreal cultures possessed various ability of accumulation of heavy metals in leaves and needles. In the study the results of heavy metals accumulation in the territory of parks and squares of the right bank of the city in leaves and needles of arboreal species of the plants present in gardening of the urbanized territories were shown: drooping birch (betula pendula), poplar balsam (populus balsamifera) and Siberian fir-tree (picea siberian). In the squares of Odessa the overestimated con-centration of iron, manganese, lead and chrome in all studied varieties of trees were observed. On En-thusiasts Square among the priority pollutants re-vealed in the leaves and needles of arboreal cul-tures were lead and chrome. In Tatyshev Park were manganese, lead and chrome, and in recreation in the Park named after May, 1 were manganese, lead and chrome. All other heavy metals were in the limits of admissible concentration.
