Toxicity of Fenitrothion to Fathead Minnows (Pimephales promelas) and Alternative Exposure Duration Studies with Fenitrothion and Endosulfan

摘要

The objectives of this study were to determine the toxic effects of fenitrothion to fathead minnows (Pimephales promelas), to investigate effects of short-term exposures to fenitrothion and endosulfan on this species, and to determine if these compounds caused delayed mortality. Fenitrothion significantly reduced survival of fathead minnows at 0.86 and 0.74 mg/l during two 14-day embryo-larvae studies.
