    Area of Science:

    • Environmental Science
    • Analytical Chemistry
    • Public Health

    Background:

    • Cigarette smoking is a significant source of environmental pollution.
    • Mercury is a toxic heavy metal with known health implications.

    Purpose of the Study:

    • To quantify mercury content in domestic and foreign cigarette brands.
    • To determine mercury release into smoke during combustion.

    Main Methods:

    • Magon's method was employed for mercury measurement.
    • A smoking machine was used to collect smoke for analysis.

    Main Results:

    • Inorganic mercury was detected in both tobacco leaf and paper of all tested cigarettes.
    • Domestic cigarettes contained approximately 60 ng of mercury, while foreign brands had about 30 ng.
    • Burning one unit length of a cigarette released 5-7 ng of mercury into the smoke.

    Conclusions:

    • Cigarettes contain inorganic mercury, with variations between domestic and foreign products.
    • Cigarette combustion releases mercury, contributing to indoor and outdoor air pollution.
    • Further research is warranted on the health effects of inhaled mercury from smoking.
