Evaluation of mercury content in combustible tobacco products by employing cold vapor atomic absorption spectroscopy and considering the moisture content: a comprehensive study

Abstract Plants are mainly made up of water, which constitutes between 80 and 90% their weight. Moisture factor comes across as one the most important in tobacco products. Rapid determination moisture content products at necessity any management plants (before after production). Therefore, concern has been raised this study to evaluate four kinds combustible using gravimetric method. In addition, a total mercury cold vapour atomic absorption spectroscopy evaluated all chosen study. Determining types does not show significant differences within product group. ranged from 7.9% bidis 25% pipe tobaccos.
