Analysis of toxic heavy metals of cigarettes by Instrumental Neutron Activation Analysis

Publication date: Available online 28 March 2017 Source:Journal of Taibah University for Science Author(s): M. Abd El-Samad, H.A. Hanafi The Instrumental Neutron Activation Analysis (INAA) technique was used to analyze 10 brands of cigarette sold in the Egyptian market. Concentrations of trace and major constituents were measured to better understand the hazardous effects of smoking Egyptian cigarette tobacco. The samples were irradiated at the core of the Second Research Egyptian Reactor ET-RR-2 and the induced activities were counted by <gamma>-ray spectrometry using an efficiency calibrated High Purity Germanium (HPGe) detector. The k0-standardization method of NAA was used to determine the concentrations of 14 elements (Ba, Br, Ca, Cd, Eu, K, Hf, Mg, Na, Rb, Sb, Sc, Th and Yb). The high concentrations found of some of these elements pose a health hazard to individuals exposed to these cigarettes
