Estimation of Biota Sediment Accumulation Factor (BSAF) from Paired Observations of Chemical Concentrations in Biota and Sediment (Final Report)
Notice The Ecological Risk Assessment Support Center (ERASC) is announcing the release of the final report entitled, Estimation of Biota Sediment Accumulation Factor (BSAF) from Paired Observations of Chemical Concentrations in Biota and Sediment.
This report was written in response to a 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 report 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.
