	abstract = {This study investigated the salinity and solvent effects on the characterization of naphthenic acids (NA) in oil sands. The mass spectra of NA were obtained using an electrospray ionization method combined with a Fourier transform ion cyclotron resonance (FT-ICR) mass spectrometer. The study showed that while monocarboxylic compounds (CnH2n+zO2) in the z=-4, -6, and -12 of the 2,3 and 6-ring NA in the carbon number range of 13 to 19 were prevalent in the dichloromethane and acetonitrile co-solvent systems, the addition of salt resulted in a reduction of the observed species, the complete elimination of dicarboxylic acids, and an 80 per cent reduction in O3 species with similar carbon number range and z values. The dicarboxylic acids were also less toxic than monocarboxylic acids. Results of the study will be used to refine methods of remediating oil sands and process water contaminated soils.
