This study was conducted to determine long-term toxic effects, on selected species of fish and invertebrates, of mine depressurization at concentrations non-lethal in acute toxicity tests. The study also includes chronic toxicity experiments, studies of sublethal effects of groundwater, and a...

McCart, P. J., Mayhood, D. W.

The general principles, approaches, and methods of aquatic biomonitoring are outlined from a review of the literature, with emphasis on those aspects directly applicable to the Alberta Oil Sands Environmental Research Program (AOSERP) study area. It is argued that an aquatic biomonitoring program...

The colonization of limestone bricks and bitumen coated limestone bricks by benthic river organisms was followed over time. After nine weeks of colonization, no massive increase in the numbers of bacteria on the bitumen was noted, suggesting that degradation was not proceeding rapidly. However,...

A climatological air quality dispersion was developed which provides more powerful analyses capabiIities than are avaiIable in traditional CDM-type models. The model incorporates a time series approach to satisfy identified user needs. The three components of the model are: the time series file...

Crowther, R. A., Lade, B. J.

This study assessed the level of secondary production in the Muskeg River and tested the validity of hypotheses generated by Crowther and Griffing (1979) regarding the trophic structure and function of the Muskeg River as a \"typical\" tributary of the Alberta Oil Sands Environmental Research...

Lock, M. A., Wallace, R. R.

The epilithic microbial and micro-invertebrate communities under conditions of light and shade were studied from April to November 1978. During a period of increasing light intensity from May to June, the level of chlorophyll a (an algal biomass indicator) and numbers of Bacillariophyta in the...

This project, which was a continuation of 1976-77 activities of AOSERP Project AF 2.0, \"Interim Report on Ecological Studies on the Benthic Invertebrates of Various Rivers in the Alberta Oil Sands Environmental Research Program Study Area, Northeastern Alberta\", was to describe the basic...
