Description
In this paper neutron activation analysis was applied to the trace element determinations in lungs of rats housed in regions with different levels of pollution. Lung samples were previously submitted to cryogenic homogenization, freeze drying and sterilization and they were irradiated with together the standards of elements under a thermal neutron flux of 1011 -1013 n.cm-2.s-1 in the IEA-R1 nuclear reactor. Concentrations for Br, Ca, Cl, Cs, Fe, K, Mg, Mn, Na, Rb, Sb, Sc, Se and Zn were determined, in general, with a good precision. In order to evaluate the accuracy of the method, the NIST 1577 a Bovine Liver and IUPAC Bowens's Kale reference materials were analyzed. Comparison among the results obtained for samples of rats originated from different regions was also performed. (author). 3 refs., 2 tabs
