RICHARDSON, S. D., J. J. ELLINGTON, F. G. CRUMLEY, J. J. EVANS, M. J. PLEWA, AND E. D. WAGNER. MEASUREMENT AND TOXICITY OF IODO-ACID DISINFECTION BY-PRODUCTS IN CHLORAMINATED DRINKING WATER. Presented at American Society for Mass Spectrometry Conference, San Antonio, TX, June 05 - 09, 2005.
Impact/Purpose:
Develop analytical methods to quantify iodinated DBPs in chloraminated drinking waters and to collaborate with CDC which is developing methods to measure iodo-THMs in human blood/urine
Description:
The goal of this work was to develop an analytical method to quantify these five iodo-acids (iodoacetic acid, bromoiodoacetic acid, (E)-3-bromo-3-iodo-propenoic acid, (Z)-3-bromo-3-iodo-propenoic acid, and (E)-2-iodo-3-methylbutenedioic acid) in drinking water, measure their occurrence in several drinking waters treated with chloramination, determine whether they are maximized in waters treated with chloramines only (compared to chlorine and chlorine-chloramines), and investigate the mammalian cell cytotoxicity and genotoxicity of the four synthesized iodo-acids (beyond iodoacetic acid).
