Short-Term Test Method for Assessing the Reproductive Toxicity of Endocrine-Disrupting Chemicals using the Fathead Minnow (Pimephales promelas)

摘要

This manual describes a test method with the fathead minnow suitable for assessing potential reproductive effects of chemicals, with an emphasis on endocrine pathways controlled by estrogens and androgens. The test is conducted with reproductively-mature animals for 21 d. Endpoints assessed include: adult survival, reproductive behavior, secondary sex characteristics, gonadosomatic index, gonadal histology, plasma concentrations of vitellogenin and sex steroids (beta-estradiol, testosterone, 11-ketotestosterone), fecundity, fertility, and if desired, F(sub 1) viability. In addition to describing the test method, guidance is presented as to interpretation of test results with respect to identifican of potential endocrine-disrupting chemicals.
