ABSTRACT- A Pellston Workshop titled "The Role of Dietborne Exposures in the Evaluation of Risk of Metals to Aquatic Organisms" was held in July 2002. The workshop was organized by SETAC, with funding from several government and industry organizations. The objective was to examine key scientific and regulatory issues associated with the toxicity of dietborne metals to aquatic biota. Discussion topics included (1) uncertainties related to dietborne metal toxicity, (2) the extent to which residue-based models/approaches can be used to analyze and/or predict dietborne metal toxicity, (3) ways to consider dietborne metal ingestion in conjunction with waterborne metal exposure, and (4) possible incorporation of the dietborne pathway into risk assessment and regulatory guidelines. These and other issues were addressed by a group of scientists and regulators drawn from the fields of aquatic ecology, toxicology, chemistry, mathematical modeling, environmental engineering, and fish and invertebrate nutrition. The participants were employed in academia, government, and industry in a variety of geographic regions. In this presentation, we will review the scientific findings of the workshop and discuss their potential regulatory implications.
