Widely spread lichen specie Flavoparmelia caperata is used in a biomonitoring
study for atmospheric trace metal pollution in natural ecosystems in
Southeastern Serbia. The concentration and distribution pattern of 21 metals
in lichens were determined by inductively coupled plasma atomic emission
spectrometry. The difference observed between metal deposition in peripheral
and central parts of lichen thalli reflected air quality changes in the last
and previous years. These findings were confirmed with principal component
analysis. Our study demonstrated the accumulation of Ba, K, Mg, Na, Tl and Zn
in peripheral parts of thalli, while As, B, Cd, Cr, Cu, Fe, Ga, In, Li, Ni,
Pb and Se were concentrated in central parts of thalli.
