Course Details

DescriptionUsing real-world examples of field and laboratory studies, the facilitator will introduce participants to the field of ecotoxicology, the study of effects of man-made chemicals on aquatic organisms. Session 1: Introduction of facilitator and his background, aims of the course, feedback from participants regarding their interests and expectations. History of environmental sciences relating to biological effects of chemicals – Silent Spring (1962) to examples of current practices (2022). A brief introduction to how data are generated and how they are used in deciding whether or not a compound is safe for use. Some guiding principles for using data in decision making. (approximately 90 minutes plus break). Session 2: Part 1: Pesticide use to protect softwood forests in New Brunswick from Spruce budworm. Historical data from NB and field studies in Ireland. Was/is there any effect on fish? (45 minutes) Part 2: Gender benders: How some chemicals affect gender in fish and invertebrates and consequences for “making” future generations. (30 minutes) Session 3: Part 1: Aquaculture: PEI mussels, are there any problems here? (30minutes) Part 2: Aquaculture: Introduction to finfish (salmon) aquaculture. Common practices and potential consequences for local species. Setting the stage for Session 4. (30-45 minutes) Session 4: Salmon Aquaculture. Use of pesticides in aquaculture, effects of these compounds on various life stages of lobsters and other marine invertebrates. Does it matter? (90 minutes plus break)
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

Course Facilitator

NameDr.Les Burridge
Dr. Burridge worked for over 40 years (nationally and internationally) with government and private labs conducting experiments and field studies to inform regulators of effects of chemicals on aquatic species. His work was part of a number of risk assessments and affected decisions on use of chemicals in Canada.
