—ontents of Cu, Pb, Zn, Cd, Mn, Fe, Al in the lichens Hypogymnia physodes (L.) Nyl. and Xanthoria parietina (L.) Th. Fr were estimated. Absolute concentrations of metals in thalli of lichens and their normalized values relative to aluminum indicate the absence of air pollution with heavy metals in the majority of Lviv park areas, whereas slight air pollution with Pb is possible in green areas of the city central zone.
