Resumo
In this study neutron activation analysis was
applied to analyze lichen samples used as atmospheric
pollutant biomonitors in order to verify if there is correlation between air pollution and its effects on the cardio
respiratory system. 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.
