Document Summary

For those of you with knowledge of toxicology, the class activity will be straightforward but for those without, it will provide a helpful resource. Individually you will explain an advantage and a disadvantage of the use of neurotoxic insecticides. You will also have the opportunity to test your group members on their understanding of the similarities and differences among chemical insecticide classes. This unit illustrates the mechanisms by which pesticides can affect exposed organisms as well as biotic and abiotic characteristics that can modify toxicity. The results of toxicity tests are used to derive ecotoxicology guidelines that are in turn used to monitor the potential for non-target effects in the environment. Collectively this information is used to inform pesticide risk assessment and regulation. Numerous and overlapping definitions of toxicology and ecotoxicology exist. Here we will consider biochemical, physiological and individual organism responses in the toxicology unit and population, community and ecosystem effects in the ecotoxicology unit.
