Species features of bioaccumulation of heavy metals in leaves of poplar Populus canadensis Moench and ash Fraxinus americana L. in the urban ecosystem

Berezin G.I., Olkova A.S.  

The search for heavy metal concentrator plants is important in terms of diagnostics and remediation. In the course of the work, the gross contents of Cd, Zn, Ni, Cu, Pb were measured in the leaves of poplar Populus Canadensis Moench and ash Fraxinus Americana L. These trees are often used in the landscaping of populated areas. Air-dry samples of tree leaves collected during one growing season at 5 sites located on the territory of Kirov (Russia, Kirov oblast) were studied by atomic absorption spectroscopy. Zinc was accumulated to a greater extent in poplar leaves. Maximum accumulation of zinc was noted in the industrial areas of the city. Ash leaves largely accumulated copper
and lead, the content of which was high throughout.
