Analyses of acute and chronic data for aquatic life. Draft report
Technical Report

OSTI ID:6568641
The Environmental Research Laboratory in Duluth Minnesota is the EPA's Center of expertise in freshwater aquatic toxicology. The Laboratory is examining ways that might be used to draw valid conclusions on the basis of a small amount of data concerning toxicity to aquatic organisms without requiring the collection of large amounts of additional toxicity data in all situations. Data concerning acute toxicity and acute-chronic ratios were obtained from draft and final aquatic life criteria documents so that several kinds of analysis could be performed. An analysis of the dependence of the Final Acute Value (FAV) on the number of Genus Mean Acute Values (GMAVs) used in its calculation demonstrated that, although for many data sets the FAV increased as the number of GMAVs increased above the minimum of eight, the FAV decreased for a few data sets. Final Acute Value Factors (FAVFs), which are intended to relate the results of one or a few acute toxicity tests to a FAV, were derived by empirical and theoretical methods. The empirical derivation of FAVFs was accomplished using specially selected samples (i.e., subsets) of acute values obtained from data sets contained in the criteria documents.
