Naphthenic acids and naphthenic acid fraction compounds (NAFCs) are associated with production of unconventional petroleum resources, especially the Athabasca Oil Sands Alberta, Canada. This complex mixture acidic organic is toxic to a variety taxa, so represents an important environmental management challenge. Thus, there clear motivation better understand occurrence characteristics NAFCs in aquatic environments, their chemical behaviour, fate. Empowered by modern high-resolution mass spectrometry analyses, improved descriptions have emerged. These studies include spatiotemporal survey describing quantities NAFCs, as well forensic methods working towards reliable source differentiations. Work has also proceeded earnest advance mechanistic understandings how affected passive phenomena, such soil sediment sorption, chemically reactive mechanisms photolysis biodegradation. Further advances describe fate behaviour they transported transformed across compartments. In context Canadian oil sands, available data dynamic compound class that both affects receiving environment. By comprehensive understanding NAs we might anticipate extent which residual effects may persist reclaimed landscapes.
