Estimation of some toxic metals from different brands of processed tobacco leaves

Chhatrapal Tarak, Beena Sharma, Amit Dubey

The aim of present study was to examine the levels of lead, cadmium and chromium in different brands of tobacco. Five different brands of processed tobacco leaves were purchased from local market of Raipur. Each sample was marked properly with a unique marking code, collected in an airtight polythene bag and transferred immediately to the laboratory. Then, samples were kept in the oven at 80 °C for 2 - 4 h. The samples were finely grinded and sieved through 100 (0.1 mm) nylon mesh. After complete drying and sieving, 1 g of each sample in three replicates was weighed with accurate scale; and acid digestion for each sample was done according to the validated procedure by NAFDAC (National Agency for Food and Drug Administration and Control). The digested samples were filtered and the contents were transferred in polythene sample bottles and analyzed for selected elements with Atomic Absorption Spectrometer. The results indicate the values obtained for Pb were ranged from 0.25 mg/kg to 0.34 mg/kg for different brands. Highest value was recorded for sample 1 (0.34mg/Kg) and remaining four samples had almost similar concentration i.e. 0.25 mg/Kg for sample 2, 3, 4 and 0.26 mg/Kg for sample 5. As compared to the permissible values recommended by WHO it is clear that all the samples of tobacco leaves have concentration of lead below the permissible value (0.5 mg/Kg). The values obtained for Cd were ranged from 0.039 to 0.049 mg/Kg. All the brands exceed the permissible values (0.02 mg/Kg) recommended by WHO (Table 2). Maximum value 0.049 mg/kg was recorded for sample 1 followed by 5, 4, 3 is 0.040 mg/kg, 0.040 mg/kg, 0.044 mg/kg respectively and minimum for brand 2 i.e. 0.039 mg/Kg. The overall Cd concentration was more than 0.02 mg/Kg. The values of Cr were ranged from 0.202 mg/Kg to 0.306 mg/Kg which was below the permissible values (1.30 mg/Kg) recommended by WHO. Maximum concentration of Cr was recorded in sample 3 and minimum in sample 2.
