MEETING IN CANADA: EMERGING ENVIRONMENTAL CONTAMINANTS AND CURRENT ISSUES

RICHARDSON, S. D. MEETING IN CANADA: EMERGING ENVIRONMENTAL CONTAMINANTS AND CURRENT ISSUES. Presented at 3rd Annual LC/MS and LC/MS/MS Applications in Environmental Analysis Conference, Guelph, ON, CANADA, April 10 - 11, 2007.
Impact/Purpose:
(1) Use a toxicity-based approach to prioritize and identify DBPs that show the greatest toxic response. (2) Comprehensively identify DBPs formed by different disinfectant regimes for the 'Four Lab Study'. (3) Determine the mechanisms of formation for potentially hazardous bromonitromethane DBPs.
Description:
Much has been achieved in the way of environmental protection over the last 30 years. However, as we learn more, new concerns arise (including potential adverse health effects, bioaccumulation, and widespread distribution). This presentation will discuss emerging environmental contaminants that the U.S. EPA and other agencies are currently concerned about. Emerging contaminants include drinking water disinfection by-products (DBPs), pharmaceuticals, perfluorooctanoic acid (PFOA), polybrominated diphenyl ether (PBDE) flame retardants, pesticide degradation products, sunscreens/UV filters, and algal toxins. Emerging DBPs include iodo-acids, iodo-trihalomethanes, bromonitromethanes, haloamides, and nitrosamines (including nitrosodimethylamine, NOMA).
