Resumo
Leaves of Casearia sylvestris, Casearia decandra and Casearia obliqua plant species, collected at the Atlantic Forest in
Brazil, were analyzed by using instrumental neutron activation analysis (INAA). Short and long irradiations using
thermal neutron flux of the IEA-R1 nuclear reactor were carried out for these analyses. Concentrations of Ca, K and
Mg were found in these samples at the percentage levels, Br, Cl, Fe, Mn, Na, Rband Zn at the mg g 1 levels and Co, Cr,
Cs, La, and Sc at the mg kg 1 levels. Comparisons were made among the element concentrations obtained in these three
Casearia species and significant differences were found for the elements Cl, Co, Cs, Cr, La, Mn, Na and Sc. The
precision and the accuracy of the results were evaluated by analyzing the certified reference materials NIST-1515 Apple
Leaves and NIST-1573a Tomato Leaves.
