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...

Ecological bench-marking and biomonitoring for detection of airborne pollutant effects on vegetation and soils
Download1980
Biomonitoring plots established in 1976 and 1977 were revisited in 1979 and quantified with respect to their vascular plant community of the lower stratum, lichen community of black spruce branches, and both soil and plant element contents. There was no measurable change in any of the above...

This report examines the effect of convective turbulence on the dispersion of pollutants emitted from tall stacks in the AOSERP area. As an introduction to this subject the structure of the convective boundary layer is described. Recent models to account for the effects of convection on plume...

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
Download1979
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...

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...

McMahon, T. A., Kramer, J. R., Denison, P. J.
An in-depth review of the literature related to deposition of gases and particulates by dry deposition and precipitation scavenging is reported. Recommendations are made on the hypotheses, algorithms or models considered to be most suitable for incorporation into a pollutant transport and...

Meteorological factors affecting ambient SO2 concentrations near an oil sands extraction plant
Download1980
Peters, R. R., Strosher, M. M.
Occurrences of maximum 0.5 h hour ground level measurements of SO2 near a point source are related to the meteorological processes at the time such that a cause analysis of the occurrences is established. Measurements, from a 10 station, continuous air quality monitoring network, range from 0.12...
