Southern Alberta Council on Public Affairs (SACPA)

Pesticides are chemicals of natural or synthetic origin, used to kill unwanted animals or plants including algae, weeds, insects, or rodents, organisms which may lower crop yields, cause or transmit diseases, damage structures and in general, have undesired impacts. We rely on the Risk/Benefit analysis for the use of pesticides, expecting to gain maximum benefits from pesticide use with minimum risks to our health and the health of the environment. There is substantial evidence that this assumption of low health risk is often false and there are in fact significant risks associated with extensive use of pesticides. The speaker will present and evaluate some of this recent evidence, explain the mechanisms of action and potential health impacts of key pesticides used in Southern Alberta, and introduce the process used in Risk Assessment for pesticides. New discoveries which might improve the use and efficacy of pesticides in the future will also be discussed. Speaker: Dr. Alice Hontela
