SUPPLEMENTARY INFORMATION:

I. Information About the Project/Document

U.S. EPA's Ecological Risk Assessment Support Center (ERASC) is a knowledge center that provides technical information and addresses scientific questions on topics relevant to ecological risk assessment at hazardous waste sites for EPA's Office of Solid Waste and Emergency Response (OSWER) and Regional Superfund/Resource Conservation and Recovery Act (RCRA) staff. Topics are submitted to ERASC by users in EPA program offices and regions. The ERASC is managed by the Office of Research and Development's (ORD's) National Center for Environmental Assessment and is located in Cincinnati, Ohio.

The ERASC recently completed an external review draft of the document titled, “Estimation of Biota Sediment Accumulation Factor (BSAF) from Paired Observations of Chemical Concentrations in Biota and Sediment.” BSAF is a parameter describing bioaccumulation of sediment-associated organic compounds or metals into tissues of ecological receptors. The draft provides information on methodologies to estimate BSAF. It is focused solely on the determination of BSAFs for nonionic organic chemicals and is primarily applicable to fish and high level shellfish, e.g., crabs. The determination of BSAFs for metals is not discussed.
