Resumo
Tobacco plant Nicotiana tabacum L. is used in the manufacture of all derivate
products and the chemistry composition resulting of smoking varies with the kind of
tobacco leaves, how they are grown, their original region, the features of preparation
and the temperature variations resulting from the incomplete combustion of tobacco.
There is a lack of information about the radiological and chemistry characterization
of the tobacco plant in international and mainly Brazilian literature. The objective of
this study was to determine the concentration of the elements As, Ba, Br, Ca, Ce,
Co, Cr, Cs, Eu, Fe, Hf, K, La, Lu, Na, Nd, Rb, Sb, Sc, Se, Sm, Ta, Tb, Th, U, Yb
and Zn in the Nicotiana tabacum L., Virginia variety, by the Instrumental Neutron
Activation Analysis (INAA) technique. The INAA was used in the Virginia variety
cultivated at IPEN and the same variety cultivated in the city of Arvorezinha, Rio
Grande do Sul by a regular producer. The samples cultivated in Arvorezinha were
separated in soil, root, stem and leaves and the samples cultivated at IPEN were
separated in substrate, root, stem and leaves. The results of rare earth elements
showed a similar behavior among the plants, with higher results in soil and substrate
and in the leaves. It was observed that the plants of the producers presented higher
concentration of the studied elements when compared to the plants cultivated in
IPEN. These higher concentrations are probably due to the addition of fertilizers to
the producer’s crop and also because these elements can accumulate in the soil due
to many years of use, different from the substrate used in the IPEN cultivation.
