Human Exposure to Perfluorinated Compounds via Smoking and Second-Hand Smoke

Pablo J. Tseng
The current study investigates the potential of human exposure to volatile fluorinated species such as fluorotelomer alcohols and acrylates as well as their non-volatile metabolites from direct or indirect inhalation of cigarette smoke. Using gas chromatography-mass spectrometry, it was observed that, there was no presence of exposure to fluorinated species via indirect inhalation of cigarette smoke, 36±4 ng of 8:2 fluorotelomer alcohol were collected and observed in the analysis of direct consumption of cigarettes. In the liquid chromatography tandem mass spectrometry analysis of the cigarette butt, wrapping paper and tobacco, there were no significant levels above background levels of non-volatile fluorinated compounds. 8:2 fluorotelomer alcohol is a compound that can degrade atmospherically and metabolically into the bioaccumulative and Potentially Toxic Perfluorooctanoic Acid (PFOA) and other metabolites. Direct consumption of cigarettes may be a source of exposure to PFCAs and other metabolites of the 8:2 FTOH.
