The element structure monitoring of birch, oak, hazel leaves and the small mammal population condition in technogeosystem

The heavy metal content in the leaves of wood vegetation main types and small mammal ecological population changes are investigated. It is established that with heavy metal air intake reduction on key sites, the Pb concentration decreased in 18 times in oak leaves and in 6 times in birch leaves; however it decreased in a much smaller degree for a number of elements (Cd, Cu, Zn). The reaction of the small mammal population is ambiguous; though there are health improvement signs in small animal population and organisms, it is not enough to state that the ecosystem was completely purified.
