NEWS-MEDICAL - Researchers at the University of California, Riverside, have completed a cross-sectional human study that compares biomarkers and metal concentrations in the urine of e-cigarette users, nonsmokers, and cigarette smokers.

They found that the biomarkers, which reflect exposure, effect, and potential harm, are both elevated in e-cigarette users compared to the other groups and linked to metal exposure and oxidative DNA damage.

"Our study found e-cigarette users are exposed to increased concentrations of potentially harmful levels of metals -- especially zinc -- that are correlated to elevated oxidative DNA damage."
