The course is designed to identify, characterize and evaluate environmental contaminants as they are related to human health and adopts a global perspective to contaminant issues. Topics include biological, chemical and physical contaminants (both well-known and emergent ones) in air, food, soil and water. The behaviour of these contaminants will be discussed. Methods of environmental health risk assessment and risk management will be introduced as will policies designed to eliminate the effects of exposure to environmental contaminants.
