The extraction of bitumen from the Alberta oil sands reserves has long been a major economic contributor to the Canadian society, but the impact this industry has had on the environment has raised concerns worldwide. The main problems are how to reclaim the area and reduce the number of tailings...

The acute and sub chronic effects of oil sands process affected water (OSPW) and its toxic component, naphthenic acids (NAs) were examined. I exposed goldfish for one (acute), or 12 (sub chronic) weeks and examined immune gene expression, macrophage function, the ability of exposed fish to...

Oil Sands Process-Affected Water (OSPW) is generated from oil sands operation processes such as mining, extraction, and upgrading. Currently, accumulated OSPW is temporarily stored in tailings ponds which are toxic to the environment and must be treated for either reuse or safe discharge in the...

One of the current technologies used by the oil sands industry to reduce the volume of fluid fine tailings and create a dry landscape is production of CT (Composite Tailings) and NST (Non-Segregating Tailings). CT and NST are engineered tailings streams obtained by recombination of fines (MFT or...

The remediation of oil sands tailings is a crucial environmental aspect of the Canadian oil sands industry. Oil sands tailings management involves the endless storage of massive volumes of fluid fine tailings (FFT). The slow gravity settling of tailings, the release of toxic compounds, and the...

The Alberta oil sands contain one of the world’s largest reserves of oil - over 169 billion barrels of bitumen are economically recoverable with current extraction technologies. Surface mining, whereby the ore is extricated from the earth and bitumen is obtained via a hot water extraction...

The accumulation of oil sands tailings poses serious environmental issues in Alberta, Canada. In the tailings ponds, the fine clays and residual bitumen form the so-called mature fine tailings (MFT) which contain 30~40 wt% fine solid particles primarily below 44 µm in size, 1~3 wt% residual...

The extraction, transport and refining of crude oil generates a diverse group of contaminants that pose a risk to both fresh and saltwater fishes. Adult fish can detect and actively avoid exposure to these pollutants; however, the embryonic and larval fish cannot outswim a toxic plume and are...

Splicing is an essential step in the post-transcriptional modification of pre-mRNAs in eukaryotes. This process is catalyzed by the spliceosome, a multi-megadalton nuclear protein-RNA enzyme which excises non-coding sequence from RNA transcripts prior to translation. Deficient or improper...

The oil sands process-affected water (OSPW) generated from bitumen extraction of oil sands by industries in Northern Alberta, Canada, is a great environmental concern because of the OSPW toxicity in the environment. This toxicity has been attributed to a group of alicyclic and aliphatic compounds...
