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...

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...

The achievement of satisfactory air quality entails the adoption of one or more air pollution control strategies. Of the four basic strategies available, only air resource management requires the use of air quality models. Atmospheric dispersion models are a subset which can be employed either...

A network of 56 permanent plots, radiating from the periphery of the Syncrude Lease, was established during the summer of 1976. This network will allow continuous quantitative monitoring of the lichen flora using photographic techniques. Since lichens are highly sensitive to air pollutants such...

The third in a series of Atmospheric Environment Service Field Studies in the Alberta Oil Sands Study Area was carried out during June 16-27, 1977. The study was designed to cover the same objectives as those of the previous two studies but for summer conditions. As a consequence, the AES...

The second in a series of Atmospheric Environment Service field studies in the Athabasca Oil Sands area was carried out during 3-13 February 1977. The objectives of the study were the same as those of the March 1976 study, namely to obtain information on the meteorology of the area and/or the...
