Resumen
Organic acids, similar in structure to naphthenic acids, have been associated with the acute toxicity of tailings produced by the oil sands industry in northeastern Alberta, Canada. Bacterial cultures enriched from oil sands tailings were found to utilize as their sole carbon source both a commercial mixture of naphthenic acids and a mixture of organic acids extracted from oil sands tailings. Gas chromatographic analysis of both the commercial naphthenic acids and the extracted organic acids revealed an unresolved "hump" formed by the presence of many overlapping peaks.

Resumen
The biodegradation of both an n-alkane and several carboxylated cycloalkanes was examined within tailings produced by the extraction of bitumen from the Athabasca oil sands. The carboxylated cycloalkanes examined were structurally similar to naphthenic acids that have been associated with the acute toxicity of oil sand tailings. The biodegradation potential of naphthenic acids was estimated by determining the biodegradation of both the carboxylated cycloalkanes and hexadecane in oil sand tailings. Carboxylated cycloalkanes were biodegraded within oil sand tailings, although compounds with meth

Resumen
The adsorption of single-ring model naphthenic acids on soils was investigated using a batch partitioning method. The influence of the molecular structure of the sorbate, the organic carbon content of the sorbent, the temperature, the solution salt (calcium chloride) concentration, and the pH on the adsorption isotherms was determined. The adsorption coefficients (Kd) for two structurally related model naphthenic acids, 4-methycyclohexaneacetic acid (4MACH) and 4-methylcyclohexanecarboxylic acid (4MCCH), were 0.18 and 0.11 mL/g, respectively.

Resumen
Naphthenic acids (NAs) are carboxylated alkanes and cycloalkanes concentrated in wastewater during oil sands processing. The general chemical formula is C{n}H{n+Z}O{2}, where n represents the number of carbon atoms and Z specifies a homologous family with 0-6 rings (Z=0 to Z=-12). The wastewater is acutely toxic to surface water organisms and is stored in tailings ponds with over 230 million m³ of fines tailings and free water. The purpose of this thesis was to provide a preliminary evaluation of the potential attenuation of NAs during groundwater flow from the ponds. Laboratory

Resumen
Adequate wastewater management is a crucial element to achieve water sustainability in the petroleum refining sector, as their operations produce vast quantities of wastewater with potentially harmful contaminants. Treatment technologies are therefore pivotal for stopping these chemicals from entering the environment and protecting receiving environments. However, refining effluents are still linked to serious pollution problems, partly because little progress has been made in determining the causative agents of the observed biological effects, resulting in non-targeted treatment.

Resumen
Oil sand deposits in the Athabasca Basin in Alberta represent one of the largest global oil reserves. The bitumen contents of oil sand shallow deposits are recovered by surface mining using modified version of the Clark hot water process. Extraction of bitumen results in extremely large volumes of process water, which are contaminated with naphthenic acids. Various ex-situ treatment techniques including ozonation, advanced oxidation, adsorption, and bioremediation have been evaluated for the treatment of these waters.

Parmi les substrats organiques, les lipides sont les plus productifs de méthane par rapport aux glucides et aux protéines; mais leur dégradation est très difficile, en raison de leur hydrolyse qui peut être l’étape limitante. Les algues peuvent être une source importante pour la production de méthane à cause de leur contenu en lipides potentiellement élevé. L’objectif d

Resumen
The In Situ Aquifer Test Facility (ISATF) has been established on Suncor Energy Inc’s (Suncor) oil sands mining lease north of Fort McMurray, Alberta to investigate the fate and transport of oil sands process-affected (PA) water in the Wood Creek Sand Channel (WCSC) aquifer. In 2008, the ISATF was used for preliminary injection experiments in which 3,000 and 4,000 L plumes of PA water were created in the WCSC. Following injection, the evolution of the plumes was monitored to determine if naphthenic acids (NAs) naturally attenuated in the WCSC and if trace metals were mobilized from the aquif
