Biography

Dr. Tony Scheuhammer is a research scientist at the National Wildlife Research Centre (Environment Canada) on the Carleton campus. He is currently an Adjunct Professor in Geography & Environmental Studies, Carleton University; and he also holds an Adjunct position with the Dept. of Natural Resource Sciences, McGill University. Tony received his Ph.D. in environmental toxicology from the University of Western Ontario and now conducts research on the ecotoxicology of metals, especially lead and mercury, and their hazards to wildlife. His research on patterns of lead exposure in hatch-year waterfowl across Canada led the way to a national prohibition on the use of Pb shot for waterfowl hunting; and his research and review of the environmental hazards of lead fishing sinkers and jigs has substantially influenced government policy to recommend replacing lead with other non-toxic materials in these products. Tony’s most current research is on the correlates of elevated methylmercury bioaccumulation through ecosystems, the subtle neurochemical effects of methylmercury exposure in fish-eating wildlife, and the development of biochemical markers of mercury exposure and effect in wildlife.

Research Interests

Dr. Scheuhammer’s primary expertise is the food-chain transfer and wildlife toxicology of environmental metals. A major focus of his research is the accumulation and ecotoxicology of lead and mercury. His current research includes studies on the exposure and bioeffects of environmental mercury in fish-eating wildlife, especially subtle neurochemical changes related to environmentally relevant methylmercury exposure; and investigations of the environmental impacts of lead from various sources, especially as relates to toxicity in avian wildlife. Dr. Scheuhammer also studies the exposure, accumulation, and bioeffects of several other metallic elements, including cadmium and selenium.
