Vanadium concentrations of 2.4 to 5.6 mg/L were lethal in 7 days to rainbow trout of wet weight 1.2-6.2 g. The LC50 varied slightly over the 12 combinations of water quality, from hardness 30 to 350 units and pH 5.5 to 8.8. The 7-day LC5O may be estimated by the following equation, which...

Acute lethality of mine depressurization water to trout-perch (Percopsis omiscomaycus) and rainbow trout (Salmo gairdneri) Volume I
Download1979
Mine depressurization water obtained from five wells on Lease 17 held by Syncrude Canada Limited, was examined for chemical composition and acute toxicity to two species of fish. In the first series of experiments, mine depressurization water was diluted with various proportions of water...

Volume 2 In order to conduct oil sands mining operations in the surface mining region of the Athabasca oil sands deposits, most regions require depressurization of the basal sandstone formations. The groundwater produced by depressurization operations is of poor enough quality to be toxic to...

Acute lethality study of G.C.O.S. dike filter drainage using rainbow trout and brook sticklebacks
Download1976
When evaluating this data, lethality (i.e. death of the organism) is the symptom being observed. Acutely lethal refers to a sample killing 50% of a population after 96 hours exposure. 1. The dike filter drainage was found to be acutely toxic to both rainbow trout and brook sticklebacks. The...

During June, July, and August of 1976 three species of amphibians were found within the Alberta Oil Sands Project area. The wood frog (Rana sylvatica) was the most abundant and widespread species and was collected at each of 20 sites examined. Boreal chorus frogs (Pseudacris triseriata...

This study assessed the level of secondary production in the Muskeg River and tested the validity of hypotheses generated by Crowther and Griffing (1979) regarding the trophic structure and function of the Muskeg River as a \"typical\" tributary of the Alberta Oil Sands Environmental Research...

An experimental investigation of the impact of fat taxes: Price effects, food stigma, and information effects on economic instruments to improve dietary health
DownloadFall 2009
This thesis investigates how a tax and warning label on less healthy snack food products may affect consumer behaviour when the imposition of the tax is a source of consumer information. A survey that included choice experiments was implemented in supermarkets. Participants were asked to choose...
