Impact/Purpose:
Lecture for NKY Chris Curran Environmental Toxicology Course. Overview of CECs and some associated studies.
Description:
This presentation will overview what Contaminants of Emerging Concern (CECs) are, provide some examples of various CECs and some of the biological and chemistry approaches to assess their exposure and effects to aquatic life. The term CECs has been used since the 1990s to identify chemical, physical or biological contaminants that have no regulatory standard, have been recently “discovered” in natural streams because of improved analytical chemistry detection levels, and potentially cause deleterious effects on aquatic life, human health, or ecosystems. Several case studies will be presented that assess estrogenic or other toxic exposure and effects found in laboratory, field deployments, experimental streams and a worldwide recognized Whole Lake dosing experiment.
