Abstract
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.
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.
Status
The document will be revised in accordance with any public comments from the external review. Then the Final document will be posted shortly thereafter.
