Document Summary

You will learn reasons pesticide use can become an international concern. Comparing and contrasting how environmental quality guidelines are developed will be a group effort. We will re-visit the ecotoxicological examples you share with the class this week. The toxicology unit illustrated the mechanisms by which pesticides can affect exposed organisms. In this unit we will consider the circumstances in which those effects can be translated to populations and/ or communities within ecosystems. The endpoints discussed in both the toxicology and ecotoxicology units are used in ecological risk assessments and to regulate the use of pesticides. The endpoints used to study ecotoxicological effects can subsequently be used in ecological risk assessment (table). Change to a less useful or appealing state. Read persistent organic pollutants: a global issue, a global response. Select three ecotoxicological endpoints that were discussed on the webpage. For each endpoint, explain a characteristic that makes it an effective indicator of ecotoxicology, in your activity log (50-150 words).
