Journal ArticleDOI
Characterization of naphthenic acids in oil sands wastewaters by gas chromatography-mass spectrometry.
TL;DR: This is the first investigation in which changes in the fingerprint of the NA fraction of process-affected waters from the oil sands operations has corresponded with measured toxicity in these waters.
Journal ArticleDOI
Acute and subchronic mammalian toxicity of naphthenic acids from oil sands tailings
TL;DR: Results indicate that, under worst-case exposure conditions, acute toxicity is unlikely in wild mammals exposed to naphthenic acids in AOS tailings pond water, but repeated exposure may have adverse health effects.
Journal ArticleDOI
Estimating the in situ biodegradation of naphthenic acids in oil sands process waters by HPLC/HRMS
TL;DR: There is indirect evidence for rapid biodegradation of relatively labile Z=0 and Z=-2 NAs in active settling basins, but the remaining steady-state fraction of N as in OSPW appear to be very recalcitrant, with half-lives on the order of 12.8-13.6 years.
Journal ArticleDOI
Naphthenic acids in athabasca oil sands tailings waters are less biodegradable than commercial naphthenic acids.
TL;DR: Low molecular mass NAs (C < or =17) are more readily biodegraded than high molecular mass (C > or =18) NAs and this results indicate that biodegradation studies using commercial NAs alone will not accurately reflect the potential biodegradability of NAs in the oil sands tailings waters.
Journal ArticleDOI
Biodegradation of naphthenic acids by microbial populations indigenous to oil sands tailings
TL;DR: Respirometric measurements of microbial activity within microcosms containing oil sands tailings were used to provide further evidence that the indigenous microbial community could biodegrade naphthenic acids and components within the extracted organic acids mixture.
