Interlaboratory Comparison of Continous Flow, Early Life Stage Testing with Fathead Minnows

摘要

Six laboratories conducted toxicity experiments according to a supplied protocol. Also supplied were the chemicals to be tested (acenaphthene and isophorone). Test organisms were fathead minnow (Pimephales promelas) embryos which were raised until 28 days post hatch. All fish were weighted and compared with the controls. Results ranged between 0.049 mg/l and 0.42 mg/l for the low solubility acenaphthene and between 1.35 mg/l and 45.4 mg/l for a more soluble isophorone. The isophorone results were strongly correlated inversely to growth of the controls which varied between 0.969 gr and 0.018 gr for a high and low, respectively.
