Simultaneous determination of cadmium and lead in cigarettes and cigarettesmoke by impaction-graphite furnace and graphite furnace atomic absorptionspectrometry

The simultaneous determination of cadmium and lead in cigarette smoke was a chieved using a unique impaction-graphite furnace atomic absorption spectro metry system (I-GFAAS), and in inert cigarette parts (whole, tobacco, filte r, and paper) using conventional graphite furnace atomic absorption spectro metry (GFAAS) following digestion using a previously established microwave digestion method. Results showed that in both the whole cigarette and the s moke there was about a factor of two in lead compared to cadmium concentrat ions, typically 17.56 compared to 31.94 mg/g for whole cigarette and 13.41 to 25.72 ng/m(3) for cigarette smoke.
