Title: Bioaccessible and Bioavailable Metals in Foods
Author: Reimer, Ken; Ollson, Chris; Hale, Beverley
Abstract: The use of bioaccessibile metals in contaminated soils as site-specific soil criteria for assessing risk is gaining regulatory acceptance as an alternate to generic criteria, although it is an approach that is somewhat in its infancy. The barrier to greater comfort with these in vitro assays is that few have been validated with in vivo data. This project will evaluate several in vitro methods for determining the bioaccessible metals in soils from contaminated sites; the criteria for evaluation will be primarily their correlation with in vivo data (which will be conducted in this project) but also their reproducibility in a laboratory setting. The metals of focus are Cu, Cd and Ni, as these metals are of interest to a number of MITHE-RN partners, and are scantly addressed in existing bioaccessibility studies, most of which have focussed on As and Pb.
