An aquatic biomonitoring program must be implemented to ensure that measures taken to protect the water systems are working, so that improvements may be made if need be.

A co-ordinated plan is proposed for the identification of toxic emissions from oil sand developments in the AOSERP study area based on interviews with over 40 specialists in various fields

Appreciable changes in biochemical functions in an epiphytic lichen, Evernia mesomorpha, were observed in response to controlled SO2 exposures even at a very low SO2 concentration (0.1 ppm)

A number of coniferous and deciduous species that had been growing on the Suncor tailings sand dike for five to seven years were fumigated with 0.34 ppm SO2 under controlled environmental conditions

Six woody forest species showed a gradual decline in CO2 gas exchange which was related to symptom development characteristic of SO2 toxicity. Paper birch most sensitive species, black spruce least

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.

General objective of this study was to describe the baseline states of the fish component of the MacKay River watershed, the largest basin on the west side of the Athabasca River

The resident fish fauna of the Steepbank River consists largely of pearl dace, brook stickleback, lake chub, longnose dace and slimy sculpin.

The impact of saline waters upon freshwater biota, having special reference to the AOSERP study area, is reviewed. Toxicity summaries for individual ions are presented.

Analyses are given for up to 12 metals and 4 pesticides with PCBs, of aquatic environment from 15 sites along or near the Athabasca River from Fort McMurray north to the confluence of the Peace River
