RequirementsN/A
ObjectivesIntroduce participants to ecotoxicology. Who does this work? Where? And Why? I hope to get across the idea that there are no perfectly safe chemicals and, at the same time, describe the checks and balances that provide the public with some confidence that chemical use in Canada is not a free for all. My talks will be full of stories from the lab and field, unexpected results
Teaching ProcessIn person, interactive lectures with power point presentations
UPEI Parking Pass Required?No
Additional Costs?No
