All acute toxicity data developed by the Columbia National Fisheries Research Laboratory, U.S. Fish and Wildlife Service, since 1965 were evaluated for quality, and a data base was established for 4,901 tests with 410 chemicals (mainly pesticides) and 66 species of aquatic animals. The data were also analyzed by various statistical approaches to make taxonomic comparisons, and to assess the degree to which various factors affect toxicity. Insects were the most sensitive group, followed by crustaceans, fishes, and amphibians. Among the four most commonly tested forms, daphnids were the most sensitive 58% of the time, followed by rainbow trout, Salmo gairdneri (35%), bluegills, Lepomis macrochirus (5%), and fathead minnows, Pimephales promelas (2%).
