1984
The results of a baseline air quality and meteorological data collection program at a site in the Athabasca oil sands region, 65 km north of Fort McMurray, Alberta are presented. Sulphur dioxide, ozone, nitric oxide, nitrogen dioxide and meteorological parameters were monitored from May 1983...

Biomonitoring for the effects of air pollution in the AOSERP study area. Report of a workshop
Download1979
This document is a summary of a workshop held on 7-8 June 1979 at the Mayfield Inn, Edmonton, Alberta, in order to provide guidance to the Alberta Oil Sands Environmental Research Program (AOSERP) concerning the establishment of a system to biologically monitor the effects of air pollution in 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...

1979
The random fluctuations of concentration levels in a plume is studied using a wind tunnel simulation of dispersion in the neutrally stable atmospheric boundary layer. A fast response hot - film probe is developed and used to measure high frequency fluctuations of helium tracer concentration in...

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...

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...
