Using Biomarkers to Distinguish Types of Smoke Exposure in Children

Biomarkers are chemicals that we can measure to estimate other harder-to-measure exposures. In this case, this project uses public use datasets of multiple biomarkers for tobacco exposure to differentiate between second- and thirdhand smoke, as well as e-cigarette smoke. Children are a population of particular concern because they are more vulnerable to the harms of tobacco exposure.
