The possibility of use for biogeochemical indication of the air anthropogenic pollution of Melitopol of epiphytic lichen Hypogymnia physodes (L.) Nyl. and bark of Robinia pseudoacacia L. were studied. Determined absolute concentrations of Cu, Pb, Zn, Cd, Co, Mn, Fe in thalli of Hypogymnia physodes and their normalized values to aluminum. These indicate a low level of air pollution park zones of Melitopol. A marked increase of the copper concentration in lichen samples near the selected industrial enterprise “Avtotsvetlyt”, indicate enrichment of this metal emissions. Revealed that little use of bark Robinia pseudoacacia for biogeochemical monitoring, possibly associated with low air pollution of Melitopol and lower compared with lichen, the bioindicative sensitivity of this object.
