Analyses are given for up to 12 metals and 4 pesticides with PCBs, of aquatic environment from 15 study sites along or near the Athabasca River from Fort McMurray north to the confluence of the Peace and Slave Rivers. There were 560 fish (8 species), 15 water, 14 sediment and a few phyto-plankton...

This project was a continuation of research begun in 1976. Earlier studies had been designed to test the moose census procedures employed, analyze census results, and determine statistically reliable moose population estimates. The project TF 1. 1.1 was designed to develop an analysis model which...

In a short period of time, the conversation around handling woody materials – deadwood such as logs, branches and stumps – has shifted dramatically. From piling and burning, to mulching and now towards keeping ‘whole logs’ on sites. The changes have led to confusion and this guide is intended to...

The results of a snowpack chemistry survey conducted in January 1978 in the Athabasca Oil Sands region of northeastern Alberta are presented. Snow collected at 60 sites within 100 km of the Great Canadian Oil Sands extraction plant was melted and analyzed for the major ions: SO4, NO3, K+, H+, Cl...

The colonization of limestone bricks and bitumen coated limestone bricks by benthic river organisms was followed over time. After nine weeks of colonization, no massive increase in the numbers of bacteria on the bitumen was noted, suggesting that degradation was not proceeding rapidly. However,...

Using Alberta, Canada, as a case study we use a trade-off analysis to systematically explore the relationship between conservation targets and economic opportunity costs in the context of coarse-filter reserve design. We use the Marxan conservation planning software to generate reserve designs at...

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...
