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
Resource
Artificial substrates were employed, water chemistry parameters measured, taxonomic identifications carried out, and productivity measurements conducted to elucidate bacterial and algal productivity
Resource
Jack pine, when fumigated with SO2 at the ambient air quality standards, exhibited various biochemical responses that can have a deleterious effect on the normal growth and yield of vegetation.
