CREED, JOHN T., P. A. CREED, C. GALLAWA, A. YOUNG, AND C. A. SCHWEGEL. EXPOSURE ASSESSMENT CONSIDERATIONS IN UTILIZING CONVENTIAL CHEMICAL AND PHYSIOLOGICAL BASED EXTRACTION TECHNIQUES PRIOR TO TO ARSENIC SPECIATION. Presented at FACSS Meeting, Orlando, FL, September 24 - 28, 2006.

Impact/Purpose:

The goal is to develop an extraction protocol that mimics the human digestive tract and then to use it to assess the bioavailable fraction of arsenic from complex dietary mixtures such as a daily composite -- to move current methods toward a better human physiologically-based exposure estimate method which approximates the "true" bioavailability of arsenic within an environmental or dietary matrix.
