In this book, the levels of trace metals in tobacco cigarettes from samples of eight (8) cigarettes sold in Ethiopia were determined. A wet digestion procedure involving a 0.5 g of oven dried cigarette sample was digested using 5 mL of HNO3 and 2 mL of H2O2 (30% w/v) at 200 C for 1:30 h. Cadmium (Cd), Lead (Pb), Zinc (Zn) and Copper (Cu) contents were determined in eight (8) brands of cigarettes commonly available in Ethiopia (both imported and Local cigarettes) by Flame Atomic Absorption Spectroscopy (FAAS).
