A laboratory study of long-term effects of mine depressurization groundwater on fish and invertebrates
Download1980-01-01
McCart, P. J., Tsui, P. T. P., McMahon, B. R., McCart, J. V.
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 review of aquatic biomonitoring with particular reference to its possible use in the AOSERP study area
Download1980
The general principles, approaches, and methods of aquatic biomonitoring are outlined from a review of the literature, with emphasis on those aspects directly applicable to the Alberta Oil Sands Environmental Research Program (AOSERP) study area. It is argued that an aquatic biomonitoring program...

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,...

Yarranton, G. A., Wallace, R. R., Davis, C. S., Crowther, R. A., Davies, M. J. E., Stevens, D. L. M., Caton, R. B.
Alberta Environment is in the process of reviewing the scientific and technical basis for refinement of a regulatory approach to the environmental impact of present and future industrial development in the Athabasca oil sands region. The review has encompassed the results of 10 years (1975 to...

1979
The epilithic microbial and micro-invertebrate communities under conditions of light and shade were studied from April to November 1978. During a period of increasing light intensity from May to June, the level of chlorophyll a (an algal biomass indicator) and numbers of Bacillariophyta in the...

Fall fisheries investigation in the Athabasca and Clearwater rivers upstream of Fort McMurray Vol I
Download1978
McCart, P. J., Mann, G. J., Jones, M. L.
Fisheries investigations were undertaken in the Athabasca and Clearwater rivers upstream of Fort McMurray in the fall of 1977. The major emphasis of these studies was to delineate actual and potential spawning areas for lake whitefish in the Athabasca and Clearwater rivers. Lake whitefish were...

Interim report on ecological studies on the benthic invertebrates of various rivers in the Alberta oil sands environmental research program study area, northeastern Alberta
Download1979
This report details preliminary experimental and survey research on benthic communities affected by selected hydrocarbons and tailings sludge produced by existing oil sands mining and upgrading operations. Taxonomic surveys of macrobenthic communities were carried out in the Muskeg and Steepbank...

Interim report on ecological studies on the lower trophic levels of muskeg rivers within the Alberta oil sands environmental research program study area
Download1979
This project (AF 2.0.2) was conducted in 1977-78 as a planned complement of another project (AF 2.0.1) on invertebrate resources. The scope of this project was to investigate productivity in the oil sands region and it involved both baseline data collection and manipulation experiments....
