Biomonitoring of Air Pollution in Bosnia and Herzegovina Using Epiphytic Lichen Hypogymnia physodes.

The aim of the study was to assess heavy metals (Cd, Cr, Cu, Fe, Mn, Ni, Pb and Zn) air pollution in Bosnia and Herzegovina by using a lichen, Hypogymnia physodes. Metal content was determined by flame atomic absorption spectrometry (FAAS) and was between very high naturality or alteration to middle naturality or alteration. Strong correlations between Cr and Ni confirmed mainly anthropogenic sources.
