Little is known of the atm. fate(s) of fluorotelomer alcs. (FTOHs), a class of high-production-volume chems. used in the production of H2O- and oil-repelling surface coatings and which have been detected in a wide variety of urban and remote environmental matrixes. We studied the uptake and photochem. of FTOHs at the surface of TiO2, Fe2O3, Mauritanian sand, and Icelandic volcanic ash. Gas-phase 3,3,3-trifluoropropanol, 4:2 FTOH, and 6:2 FTOH exhibited significant uptake to each of the surfaces under study. The sand- and ash-catalyzed heterogeneous photooxidation of 6:2 FTOH resulted in the rapid production and subsequent slow degradation of surface-sorbed perfluorinated carboxylic acids (PFCAs). We suggest that this transformation, which proceeds via saturated and unsaturated fluorotelomer carboxylic acid intermediates (6:2 FTCA/FTUCA), is catalyzed by Fe and Ti contained within the samples. These results provide the 1st evidence that the heterogeneous oxidation of FTOHs at metal-rich atm. surfaces may provide a significant loss mechanism for these chems. and also act as a source of aerosol-phase PFCAs close to source regions. Subsequent long-range transport of these aerosol-sorbed PFCAs has the potential to join oceanic transport and local gas-phase FTOH oxidation as a source of PFCAs to Arctic regions.
