Resumo
Tobacco addiction has been mentioned as a leading cause of preventable illnesses and premature
disability since tobacco smoking is the main cause of lung cancer and one of the factors that most contribute to the
occurrence of heart diseases, among others. The herbaceous species Nicotiana tabacum is a plant of the solanaceae
family used for tobacco production. Some authors have conducted research about heavy metals and the toxicity of
tobacco. It is, frequently, found in low concentrations in the ground, superficial and underground waters, even
though they do not have environmental anthropogenic contributions. However, with the increase of industrial
activities and mining together with the agrochemical use of contaminated organic and inorganic fertilizers, an
alteration of the geochemical cycle occurs. As a consequence, the natural flow of that materials increases and release
into the biosphere, where they are often accumulated in the superior layer of the ground, accessible to the roots of the
plants. During planting and plant development, fertilizers and insecticides, including organochlorines and
organophosphates, are used; consequently, the smoke from cigarette smoking presents various toxic substances,
including heavy metals, such as Chromium (Cr), Manganese (Mn) and Antimony (Sb). Elements studied in this work.
The procedures for the preparation of the samples were carried out in our laboratories and submitted to irradiation
with thermal neutrons at IPEN/CNEN-SP, in the IEA-R1 research reactor. The irradiated material was, then,
analyzed by gamma spectrometry, using a high purity germanium detector (HPGe).
