The Environmental Residue Effects Database (ERED) is a database maintained by the U.S. Army Corps of Engineers that pairs data regarding the bioaccumulation of toxicants in tissue (via tissue residue) to endpoint effects such as mortality, growth, or physiological and biochemical responses. Response data also include low effect detected (LOED) and no effect detected (NOED) concentrations. This database is derived from 2329 peer-reviewed references regarding 413 chemicals. The database covers literature from 1964 to the present and includes more than 15,000 records. This database is updated with 300 or more records every year on average. The ERED database is specific to sediment toxicity and the effects of contaminates in dredged materials on freshwater organisms. It is intended to be used in evaluating the potential for contaminate concentrations of dredged sediment to have unacceptable adverse effects on aquatic organisms. Although the ERED database was designed as a tool for the Army Corps of Engineers to manage adverse effects of dredging, it is widely applicable to sediment toxicity studies and management.
