Abstract

Samples of the lichen Canoparmelia texana collected in seven differentsites of Săo Paulo State and one site of the Paraná State wereanalysed by neutron activation analysis in order to obtain information onthe air quality in these regions and also to select a region of interest forthe evaluation of baseline level of elements in lichen species. Concentrationsof the elements Al, As, Br, Ca, Cd, Cl, Co, Cs, Fe, Hf, K, Mg, Mn, Na, Rb,Sb, Sc, Se, Ti, Th, U, V, Zn and lanthanides were determined and a preliminarycomparisons was made between the results obtained for samples collected indifferent sites.
