2008 Meeting in Germany: Emerging Environmental Contaminants and Current Issues
Citation:
RICHARDSON, S. D. 2008 Meeting in Germany: Emerging Environmental Contaminants and Current Issues. Presented at 2nd International Symposium on Genotoxicity in Aquatic Systems: Causes, Effects and Regulatory Needs, Dessau, GERMANY, April 14 - 16, 2008.
Impact/Purpose:
Characterize risks associated with drinking water sources, treatment, distribution, and use.
Description:
This presentation will discuss emerging environmental contaminants that are currently of concern to the U.S. EPA and to other agencies. Emerging contaminants include drinking water disinfection by-products (DBPs), perfluorinated chemicals, pharmaceuticals, flame retardants, benzotriazoles, gasoline additives, pesticide degradation products, sunscreens/UV filters, and algal toxins. Emerging DBPs include iodo¬acids, iodo-trihalomethanes, bromonitromethanes, haloamides, and nitrosamines (including nitrosodimethylamine, NDMA). New toxicological research is revealing that some of these emerging DBPs are more genotoxic and cytotoxic than DBPs currently regulated, and the use of newer alternative disinfectants (chloramines, ozone, chlorine dioxide) can increase their formation.
