NIEHS/EPA PCBs - Monitoring and Detection
Internet-based seminar
Hosted by NIEHS & U.S. EPA/OSRTI

This seminar, sponsored by the National Institute for Environmental Health Sciences (NIEHS) and U.S. EPA Office of Emergency and Remedial Response, will discuss the limitations of Aroclor (commercial PCB mixture) analysis and why congener analysis provides for better decision-making with regards to human health and ecological risks of exposure to polychlorinated biphenyls (PCBs). Andy Beliveau, of the EPA's Office of Environmental Measurements and Evaluation, will focus on how congener analysis can be used to detect total PCBs, WHO congeners, as well as environmentally modified PCBs. The pros and cons of each type of congener analysis will be discussed as well as the costs. The major uses of each type of analysis will be put in a historical framework, as well as presenting the state-of-the-art current applications. In addition to the discussion of congener analysis, Dr. Sylvia Daunert, of the University of Kentucky Superfund Basic Research Program, will present her team's current work on development of genetically engineered cell-based biosensing systems. Both PCBs and their breakdown products have been shown to have significant effects on human health. The researchers are developing optical sensing systems for the detection of PCBs and their breakdown products found in hazardous waste sites. Current work includes the development of biosensing systems for chlorocatechols, which are toxic intermediates often produced by the breakdown of PCBs.
