Modulation of brain serotonin by benzyl butyl phthalate in Fundulus heteroclitus (mummichog).

Endocrine-disrupting chemicals have been known to alter important animal behaviors by modulating serotonin (5-hydroxytryptamine, 5-HT) and dopamine. F. heteroclitus (mummichog) brain serotonin and dopamine levels were quantified by enzyme-linked immunosorbent assay (ELISA) following a 28-day exposure regimen involving daily doses of either 0.
