    NNN – a suitable biomarker of exposure from smoke and new nicotine delivery products?

    PLUYM N.; TAUCHER J.; SCHERER G.; SCHERER M.
    ABF Analytisch-Biologisches Forschungslabor GmbH, Planegg, Germany
    N-Nitrosonornicotine (NNN) is believed to play a critical role in the development of cancer in tobacco users and was therefore classified by the International Agency for Research on Cancer (IARC) as a Group 1 carcinogen. Hence, urinary NNN is commonly ...

    Analysis of propylene oxide and glycidol in tobacco smoke and e-cigarette vapour

    LANDMESSER A.; SCHERER G.; PLUYM N.; SCHERER M.
    ABF Analytisch-Biologisches Forschungslabor GmbH, Planegg, Germany
    We recently performed a clinical study with e-cigarette users (vapers) and smokers. The stable-isotope labeled e-cigarette constituents propylene glycol, glycerol, and nicotine in the test e-cigarette were used in order to investigate the e-cigarette ...
