Abundant naphthenic acids in oil sands process‐affected water: studies by synthesis, derivatisation and two‐dimensional gas chromatography/high‐resolution mass spectrometry

Abstract

The data support the contention that the three abundant unknowns were indeed C(16) tetracyclic acids. An equally rigorous approach will be necessary to characterise further acids in such mixtures. This is important so that chemistry can be used to guide the search for toxic modes of action.
