Heavy metal dynamics in the Athabasca River: Sediment concentrations prior to major Alberta oil sands development
Download1977
Exploitation of the bituminous sands may elevate heavy metal levels in the sediments of drainage systems of the AOSERP area via waterborne or airborne emissions. One hundred and six dredged sediments and twenty-four sediment cores were collected from the Athabasca River system from just above...

Heavy metals in bottom sediments of the mainstem Athabasca river system in the AOSERP study area
Download1978
Dredged sediments and sediment cores were collected from sites along the Athabasca River system from between Fort McMurray and the confluence of Riviere des Rochers with the Slave River. A selected sample suite representing all of the drainage units and textural variations was analysed by...

Interim report on a comparative study of benthic algal primary productivity in the AOSERP study area
Download1979
Hickman, M., Charlton, S. E. D., Jenkerson, C. G.
Studies concentrating upon the epilithon were conducted in five tributary rivers flowing into the Athabasca River: the Muskeg, Steepbank, Hangingstone, MacKay, and Ells rivers. The species composition of the epilithic algae was determined during June to November 1978. Diatoms and blue-green...

Interim report on ecological benchmarking and biomonitoring for detection of air-borne pollutant effects on vegetation and soils, 1975 to 1978
Download1979
A set of 11 sites were established in the Alberta Oil Sands Environmental Research Program study area to provide baseline information on vegetation and soils with respect to air pollution impact. Sites were strategically located for use in long-term biomonitoring and were described with respect...

Interim report on physiology and mechanisms of air-borne pollutant injury to vegetation, 1975 to 1978
Download1979
Biochemical studies conducted under controlled conditions suggested that low concentrations of SO2 which normally do not produce any visual symptoms on the foliage cause injury to forest vegetation by altering pigment (chlorophyll, phaeophytin and chlorophyllide) metabolism, by inhibiting lipid...

Interim report on symptomology and threshold levels of air pollutant injury to vegetation, 1978-79

Malhotra, S. S., Addison, P. A.
The dominant woody boreal forest plant species were fumigated with 0.34 ppm SO2 under controlled conditions in the laboratory in order to rank their physiological and visual sensitivities to the air pollutant. Deciduous trees and shrubs were much more sensitive than conifers, presumably because...

Interim report on the acidification of Lake 223, experimental lakes area: Background data, the first year of acidification (1976), and pilot experiments
Download1979
Wagemann, R., Hesslein, R. H., Schindler, D. W.
At the outset of AOSERP there was considerable concern that significant quantities of acid precipitation and heavy metals emanating from oil sands plants might adversely affect lakes near the oil sands area. Thus, the Aquatic Fauna Technical Research Committee initiated this project with the...

Inventory of water use requirements and effluent discharge characteristics related to oil sands development
Download1980
An inventory of historical data on water use requirements and effluent discharge characteristics related to oil sands developments has been collected and tabulated. The inventory data indicate that surface water bodies are the main sources of the water supply and main recipients of effluent. ...

Investigations of the spring spawning fish populations in the Athabasca and Clearwater Rivers upstream from Fort McMurray: Volume 1
Download1979
Fisheries investigations were undertaken in the spring of 1978 (28 April to 25 June) in the Athabasca and Clearwater rivers upstream of Fort McMurray. The major objectives of the studies were to determine what spring spawners utilized these sections of the Athabasca and Clearwater rivers; to...

Lake acidification potential in the Alberta oil sands environmental research program study area
Download1979
Numerous lakes in Scandinavia and eastern North America have been damaged by acidic precipitation induced by anthropogenic oxides of sulphur and nitrogen. On first approximation, lakes near present oil sands operations would not be susceptible to acidification due to buffering provided by their...
