D. George Dixon

• Effects of toxic chemicals, including metals and oilsands process water, on aquatic organisms, principally fish.
• Biotic modifying factors of toxicity.
• Development of methods for environmental effects monitoring.
• Physiologically based pharmacokinetic modelling of contaminant levels in fish.

Professor Dixon has more than 35 years experience in aquatic toxicology and environmental risk assessment.

Throughout his career he has also served as an advisor on metal contamination issues to Environment Canada, the Department of Fisheries and Oceans, the Department of Justice (Canada), the U. S. Environmental Protection Agency, the U. S. National Oceanographic and Atmospheric Administration, the Department of Justice (US) and the World Health Organization, among others.

He maintains an active research program, which at present is focused on development of methods for environmental effects monitoring, methods of assessing the environmental risks associated with exposure of aquatic organisms to metal mixtures, and on the aquatic environmental effects of oil sands extraction in northern Alberta.

Professor Dixon has developed and taught numerous courses in environmental toxicology and assessment. 

Professor Dixon has authored more than 180 refereed publications. Recent publications include
