A laboratory study of long-term effects of mine depressurization groundwater on fish and invertebratesDownload
This study was conducted to determine long-term toxic effects, on selected species of fish and invertebrates, of mine depressurization at concentrations non-lethal in acute toxicity tests. The study also includes chronic toxicity experiments, studies of sublethal effects of groundwater, and a...
A co-ordinated plan is proposed for the identification of toxic emissions from oil sand developments in the AOSERP study area. Interviews with over 40 specialists in various fields relevant to this study developed essentially no confirmed awareness of existing biological stresses due to...
Selected chemical and physical properties of the tailings pond were examined in 1980. The distributions of specific variables with depth and season within the tailings pond were determined (temperature, pH, conductivity, suspended particulate matter, total solids, bitumen, major anions, major...
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...
The purpose of this study was to determine the acute and subacute toxicity of bitumen to rainbow trout. The bitumen was collected along the banks of the Athabasca River downstream of Fort McMurray during 1984. Prior to experimentation, the bitumen was fractionated in water at 35°C, using an...
Acute lethality of mine depressurization water to trout-perch (Percopsis omiscomaycus) and rainbow trout (Salmo gairdneri) Volume IDownload
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...
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...
Al-Induced, 51-Kilodalton, Membrane-Bound Proteins Are Associated with Resistance to Al in a Segregating Population of WheatDownload
Incorporation of S-35 into protein is reduced by exposure to Al in wheat (Triticum aestivum), but the effects are genotype-specific. Exposure to 10 to 75 mu M Al had little effect on S-35 incorporation into total protein, nuclear and mitochondrial protein, microsomal protein, and cytosolic...
