A computerized model has been developed to estimate wildlife exposure in the Canadian environment to substances through inhalation and ingestion of food, water and soil. This Windows application was developed in Visual Basic using Microsoft Access databases and designed to make the evaluation process consistent, transparent and efficient. Bird, mammal, amphibian and reptile species were selected on the basis of food guild, body size, habitat and distribution in Canada. Intake rates were estimated using allometric equations or measured intake rates when available. Ingestion rates were estimated from free-living metabolic rates and dietary composition. With the information, the authors will develop the exposure scenarios required for assessments of risk to wildlife from priority substances listed in the Canadian Environmental Protection Act.
