Genotoxicity and Mutagenicity of Extractable Organics from Oil Sands Process-Affected Water
DownloadFall 2015
Oil sands process-affected water (OSPW) is produced in the surface mining industry during the hot-water extraction of bitumen from oil-sands ore. Its acid extractable organic (AEO) fraction is known to be acutely toxic, but few studies have addressed its genotoxicity or mutagenicity. Here, the in...

Monitoring Macrophage Immune Gene Expression Profiles as an Early Indicator System for Examining the Bioactivity of Oil Sands Process Affected Waters
DownloadFall 2021
Oil sands process-affected waters (OSPW) are by-products of bitumen (i.e. oil) extraction from the oil sands located in northern Alberta. These large volumes of water are held in tailings ponds and cannot be released due to their potential toxic effects. Overall, tailings ponds and mining...

Fall 2018
The continuing use of crude oil and development of the oil industry have resulted in complex hydrocarbon mixtures becoming common environmental contaminants. These contaminants, such as oil sands process affected water (OSPW) and crude oil, are especially of concern in aquatic ecosystems. OSPW...

The evaluation of toxic effects induced by exposure of mammals to oil sands process-affected water and its organic fraction
DownloadSpring 2018
Oil sands process-affected water (OSPW) produced by the surface-mining oil sands industry in Alberta, has been shown to be toxic to a variety of organisms. Much of this toxicity has been attributed to the dissolved organic compounds, primarily naphthenic acids (NAs). Under a no-release practice,...

The impacts of metal and salts similar in composition to Oil sands processes affected water (OSPW) on Rainbow trout respirometry, gill structure, and gill enzyme dynamics
DownloadFall 2018
Remediation of Northern Athabasca Oil sands areas has become an essential goal for engineers, biologists and industry stakeholders. Tailing ponds containing oil sand process-affected water (OSPW) have been growing in number as a byproduct of bitumen extraction activity. Treatment of OSPW can...

Toxic effects induced in mammalian immune cells after in vitro exposure to oil sands process-affected water and its fractions
DownloadFall 2019
Oil sands process-affected water (OSPW) is produced by the surface mining industry in Alberta as a byproduct of the Clark hot water process, the currently used extraction method of crude oil from bitumen/tar sands. Under a provincial zero release policy all produced OSPW must be stored on site....

Toxicological Characterization of Hydraulic Fracturing Flowback and Produced Water Exposures to Aquatic Organisms
DownloadFall 2021
Hydraulic fracturing is an unconventional oil and gas extraction method used to liberate oil and gas reserves from low permeability geological formations by injecting large quantities of fracturing fluid into the well-bore under high pressures. A by-product of this process is flowback and...

Turbidity Mitigation in an Oil Sands End Pit Lake through pH Reduction and Fresh Water Addition
DownloadFall 2016
The remediation of oil sands wastes such as fluid fine tailings (FFT) and oil sands process-affected water (OSPW) are of increasing concern in the oil sands industry. End pit lakes are one remediation option currently being researched at commercial scale in Base Mine Lake (BML) operated by...
