Abstract
Accumulation of heavy metals and anatomical changes in the epidermis of leaves of Betula verrucosa and Plantago maior under the conditions of techno-genous contamination is considered. An increase in Cu, Zn and Pb content of vegetative organs of Plantago maior, as well as in the sap and leaves of Betula verrucosa in a gradient of toxic load has been found. The reaction of leaf epidermis is expressed in a decrease of the number of stomata in the two species.
