toxicity assessment of collected fractions from an extracted naphthenic acid mixture.	recent expansion within the oil sands industry of the athabasca basin of alberta, canada has led to increased concern regarding process-affected wastewaters produced during bitumen extraction. naphthenic acids (nas) have been identified as the primary toxic constituents of oil sands process-affected waters (ospw) and studies have shown that with time, microbial degradation of lower molecular weight nas has led to a decrease in observed toxicity. as earlier studies identified the need for an "une ...	2008	18555508
diethylaminoethyl-cellulose clean-up of a large volume naphthenic acid extract.	the athabasca oil sands of alberta, canada contain an estimated 174 billion barrels of bitumen. during oil sands refining processes, an extraction tailings mixture is produced that has been reported as toxic to aquatic organisms and is therefore collected in settling ponds on site. investigation into the toxicity of these tailings pond waters has identified naphthenic acids (nas) and their sodium salts as the major toxic components, and a multi-year study has been initiated to identify the princ ...	2006	16469358
