XIONG, G. AND J. M. VAN EMON. IMMUNOAFFINITY CHROMATOGRAPHY COUPLED WITH LC-MS FOR THE IDENTIFICATION AND DETERMINATION OF INDIVIDUAL PYRETHROIDS AND THEIR MAIN METABOLITES IN ENVIRONMENTAL SAMPLES. Presented at American Chemical Society 232nd National Meeting, San Francisco, CA, September 10 - 14, 2006.
Impact/Purpose:
The overall goal of this research program is to identify those chemicals, pathways, and activities that represent the highest potential exposures to children and to determine the factors that influence these exposures. The following objectives will address this goal:
Revise and refine the existing research plan for children's exposure measurements research.
Collect measurement data on children's exposures.
Provide analytical support to children's pesticide exposure research.
Develop analytical methods for pesticides in duplicate diet food samples.
Develop and apply analytical methods for other chemicals including but not limited to brominated diphenyl ethers, phthalates, perfluorinated chemicals.
Evaluate the impact of chiral chemistry on the risk to children and exposure assessment.
Provide support to the National Children's Study.
Perform data analyses to fill critical data gaps.
Conduct analyses of dietary samples and refine the dietary model for the dietary exposure algorithm.
Description:
This is an ABSTRACT of an oral presentation which will be given at the 232nd ACS National Meeting. This work describes the development of a novel method for efficient screening and determination of commonly used pyrethroid pesticides and their 3-PBA metabolites based on the combination of immunoaffinity chromatography and liquid chromatography-mass spectrometry techniques.
