Advances in mass spectrometry in the authors’ and key collaborators’ research are reviewed for analysis of oil sands naphthenic acids fraction compounds (NAFCs) and industrial process chemicals, sulfolane and alkanolamines in wetlands. Focus is given to developments of analyses of NAFCs in constructed wetland treatment systems and natural wetlands in the Athabasca oil sands region, Alberta, Canada. The analytical developments are applied to show the utility of wetlands to sequester and oxidize oil sands naphthenic acids. The advancements in molecular characterization led to the first application of high-resolution mass spectrometry (Fourier transform ion-cyclotron resonance; and Orbitrap mass spectrometry) for elucidation of toxic mono-and dicarboxylic NAFCs in oil sands environmental samples. Key findings reveal that oil sands NAFCs are not limited to saturated structures, but contain a diverse range of components, many of which contain S, N, heteroatomic species and aromatic species. Other developments of mass spectrometry methods for industrial process chemicals show for the first time that the completely water-miscible chemical, sulfolane, translocate to upper portions of cattails at natural wetland sites in the Canadian environment. Likewise, wetland-plant mediated changes of complex mixtures of alkanolamines were revealed based on the coupling of ion chromatography mass spectrometry and ultrahigh resolution mass spectrometry. The advances in mass spectrometry are of particular benefit to Canada, for development of soil and water quality guidelines for oil sands NAFCs and process chemicals. In turn, the water quality guidelines serve to protect Canadian aquatic environments.
