Abstract
Geochemical studies were made to estimate the modern
ecological state of the unique submediterranean landscapes
of the Black Sea northeastern coast of Russia. A group
of simple and bioindicators. Different parts of typical
trees and bushes (leafs, rind, brunches, fruits), lichens,
grass were chosen as bioindicators. It is ascertained
that the composition of vegetation and soils depends
on various natural and anthropogenic factors: the character
of migration of elements, soil features, philogenetic
and ontogenetic biochemical specialization of plants,
the exposition of the slopes, the type of anthropogenic
impact. The urban and industry areas are characterized
by the formation of anomalies in soils and vegetation.
The concentration of Pb and Cd increases along the
motorways and parking areas, Cu in the soils of vineyards.
The trend of Cu high concentration retains in ecosystems
of former vineyards during some decades.
