Assessing Whether Exposure to Low Levels of Estrogen Whose Biological Actions Mimic that of Effluent from Great Lakes Sewage Treatment Plants Poses a Threat to the Reproductive Health of Fish

Male fathead minnows will be raised in water with concentrations of   estrogen-mimicking compounds similar to those that researchers find   to be released by sewage treatment plants and pulp mills along the   Great Lakes.  The researchers will examine whether these relatively   low levels of estrogen-mimicking  chemicals change any aspect of the   minnows' development-particularly by monitoring the presence of a   female yolk precursor protein, vitellogenin.   Based on a   combination of field and laboratory studies, the researchers plan to   determine if typical effluent from treatment facilities will impair   the ability of small populations of male fish to reproduce.
