A fisheries and water quality survey of ten lakes in the Richardson Tower area, Northeastern Alberta. Vol I: Methodology, summary, and discussion
Download1980
A fisheries and water quality survey was conducted in September 1979 on 10 small lakes (67.4 to 338.9 ha) in the vicinity of Richardson Tower, approximately 140 km north of Fort McMurray, Alberta. The major objectives were: (1) to determine morphometric and water quality characteristics in...

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...

Calculations of annual averaged sulphur dioxide concentrations at ground level in the AOSERP study area
Download1977
The Climatological Dispersion Model and the input data required for calculation of annual averaged values of sulphur dioxide concentrations at ground level are described. The most important meteorological input to the model is the long-term joint frequency distribution of winds in the vicinity of...

A field study has been undertaken at the Sandalta lease near Fort McMurray to determine the sulphur dioxide dry deposition velocities above and within a tree canopy. The concentration gradient method has been used to compute fluxes and dry deposition velocities. The covariance of temperature...

Air pollution and its effects on various ecosystems has been a subject of increasing controversy. The European forest damage situation has heightened the public's awareness of the problem. Historically, the observed pollution damage was believed to be due mainly to sulphur dioxide pollution. ...

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...

Malhotra, S. S., Addison, P. A.
Six boreal forest plant species were fumigated in a newly developed environmental growth chamber with SO2 control capability,for up to 40 days at 0.34 ppm SO2. All species showed a gradual decline in CO2 gas exchange which was related to symptom development characteristic of SO2 toxicity. Paper...

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...
