Biota-Sediment Accumulation Factor Database

Welcome to the BSAF Database

The biota-sediment accumulation factor (BSAF) database is a collection of bioaccumulation data obtained from peer-reviewed literature and reports submitted by U.S. government agencies. The database was developed by researchers at the U.S. Army Engineer Research and Development Center, Environmental Laboratory, through support provided by the Dredging Operations Technical Support Program. The data are useful for comparing measured tissue concentrations from a bioaccumulation test — such as those performed to evaluate dredged sediment — to published information that describes the ratio between the lipid normalized chemical concentrations in the organism's tissue to organic carbon noramlized concentration in the sediment.
