Canoparmelia texana lichenized fungii species was chosen for passive biomonitoring of atmospheric pollutants. The population group selected for this study was adults over 45 years. Lichen samples collected in Sa˜o Paulo city were cleaned, freeze-dried and ground for the analyses. Aliquots of samples were irradiated at the IEA-R1 nuclear research reactor for short and long periods along with synthetic element standards. The induced gamma activities of the samples and standards were measured using a gamma ray spectrometer with an HPGe detector and the concentrations of As, Ba, Br, Ca, Cd, Cl, Co, Cr, Cs, Fe, Hf, K, Mg, Mn, Na, Rb, Sb, Sc, Se,Th, V, Zn and lanthanides were determined. For quality control of the results, certified reference materials were analyzed together. Mortality data for the population due to cardiorespiratory diseases were obtained from the database of the Secretariat of Health of the Sa˜o Paulo Municipality for the years 2005–2009. Results obtained point to vehicular and industrial emissions as the origins of pollutants in Sa˜o Paulo city. The statistical treatment of Pearson’s correlation applied to the results of lichen element concentrations and mortality rates indicated significant positive correlation for the elements Co, Mn and Zn for adults.773-779openAccesslichenssample preparationbiological indicatorsneutron activation analysismulti-element analysisair pollutioncardiovascular diseasesrespiratory system diseasescomparative evaluationsArtigo de periódico129910.1007/s10967-013-2698-1https://orcid.org/0000-0002-6318-6805
