Short‐term bioassays were conducted with adult fathead minnows and hexavalent chromium, phenol, and sodium pentachlorophenate at 2 temperatures to determine the relationship of the 96‐hour LC 50 to the lethal threshold concentration. The lethal threshold concentration was less than the 96‐hour LC 50 in 10 of 12 bioassays, was affected by temperature, and was not a constant multiple of the 96‐hour LC 50 for any of the toxicants tested.
