Correlation analysis of elements in tobacco leaf, cigarette and cheroot samples Dr.Hla Win Aung Dr.Khin Maung Htwe Dr.Tin Htun Naing Energy dispersive X-ray fluorescence spectroscopy was used for the multi-elemental analysis of four tobacco leaves, one brand of cigarette and cheroot. The dried samples of tobacco leaves, cigarette, cheroot and ashes of the samples have been analyzed for fourteen elements like potassium (K), calcium (Ca), arsenics (As), bromine (Br), rubidium (Rb), strontium (Sr), titanium (Ti), zirconium (Zr), iron (Fe), nickel (Ni), copper (Cu), zinc (Zn), selenium (Se) and lead (Pb). As, Ni, Cu, Zn, Sr, Se and Pb have the averages of 0.7, 1.28, 20.58, 57.38, 203.83, 0.5, and 3.73 ppm and 0.73, 1.75, 71.22, 184.3, 694.02, and 7.87 ppm in samples and ashed samples respectively. Statistical correlations are found to exist between K and Ca (-0.99), Sr and K (-0.8), Sr and Ca (+0.8), Sr and Br (+0.6), Pb and Br (-0.6), Zn and Sr (-0.8) and Cu and Ti (+0.9), Pb and Ti (+0.8) and Pb and Cu (+0.8). 2017 http://hdl.handle.net/20.500.12678/0000000290 https://meral.edu.mm/records/290
