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.
