View Long Abstract
Biomarkers are better able to assess exposure and consequently provide more accurate estimates of health risk from such exposures. Nicotine levels in toenails and hair have been recently developed to determine exposure to active and passive smoking in large epidemiological studies. They have advantages over other biomarkers by having longer half life and more stable average exposures, they can also be cost-effective in large population studies, there is ease of collection that can be done by study participants, and the ability to store the samples at room temperature for extended periods of time. Findings from recent studies will be discussed.
