Gonzalez, A. C., S. W. Krasner, H. Weinberg, AND S D. Richardson. SOLID PHASE MICROEXTRACTION FOR TRACE LEVEL ANALYSIS OF DISINFECTION BY-PRODUCTS. Presented at 48th American Society for Mass Spectrometry Conference, Long Beach, CA, June 11-15, 2000.
Impact/Purpose:
(1) Use toxicity-based approach to 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:
This presentation focuses on the development of a solid-phase microextraction (SPME)-gas chromatography (GC)/ion trap mass spectrometry (MS) method for the analysis of semivolatile disinfection by-products (DBPs) in drinking water in the low ug/L range. These DBPs were selected from approximately 600-700 DBPs that have been reported in the literature,
due to their possible adverse health effects, as judged by expert toxicologists.
