Biota-Sediment Accumulation Factor Database

US Army Corps of Engineers ERDC Dredging Operations Technical Support


Welcome to the BSAF Database

The 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 chemical concentrations in the organism's tissue to concentration in the sediment.
