Estimation of Biota Sediment Accumulation Factor (BSAF) from Paired Observations of Chemical Concentrations in Biota and Sediment (External Review Draft)
The Ecological Risk Assessment Support Center (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 for nonionic organic chemicals. This was announced in the June 8, 2006 Federal Register Notice.

Impact/Purpose:
This report focuses on the determination of Biota-Sediment Accumulation Factors (BSAFs) for nonionic organic chemicals and is primarily applicable to fish and high level shellfish, e.g., crabs.
Description:
This report was written in response to a March 2004 request from EPA's Ecological Risk Assessment Forum (ERAF) for information about estimating Biota-Sediment Accumulation Factors (BSAFs). BSAF is a parameter describing bioaccumulation of sediment-associated organic compounds or metals into tissues of ecological receptors. The External Review Draft addressing this request 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.
