• Plants are mainly made up of water, which constitutes between 80 and 90% of their weight. Moisture factor comes across as one of the most important in tobacco products. Rapid determination of moisture content in tobacco products comes at necessity in any tobacco management plants (before and after production). Therefore, the concern has been raised in this study to evaluate the moisture content in four kinds of combustible tobacco products using the gravimetric method. In addition, a total mercury content using cold vapour atomic absorption spectroscopy has been evaluated in all chosen combustible tobacco products in this study. Determining moisture content in four types of tobacco products does not show significant differences within a product group. Moisture content ranged from 7.9% in bidis to 25% in pipe tobaccos. Mercury content in tobacco ranged from 13 µg/kg to 32 µg/kg while in cigarette wrapper paper and filter from the limit of detection (LOD) < 1.3 µg/kg to 8.2 µg/kg. As evidenced, cigarette wrapper paper and filters alone are unlikely to be a significant source of consumer exposure to mercury. However, the proposed sample preparation method provides good results for the preparation of specific material, such as tobacco products. Graphical abstract
