Ecological Benchmarks
Screening ecological benchmarks are used to identify chemical
concentrations in environmental media that are at or below thresholds for
effects to ecological receptors. The Environmental Sciences Division of
Oak Ridge National Laboratory developed and compiled a comprehensive set of
ecotoxicological screening benchmarks for surface water, sediment, and
surface soil applicable to a range of aquatic organisms, soil
invertebrates, and terrestrial plants. These benchmarks, or updates
performed in collaboration with The Institute for Environmental Modeling at the
University of Tennessee and the Bechtel Jacobs Corp., are provided as a
searchable database. Links to supporting technical reports from which the
benchmarks were obtained are also provided.
In addition, benchmarks from many other national and international sources
have been added to the database in September 2003. These additions are also
presented in the SADA risk
assessment software.
