Immunomodulatory effects of dietary exposure to selected polycyclic aromatic hydrocarbons in the bluegill (Lepomis macrochirus).

Polycyclic aromatic hydrocarbons (PAH) have been demonstrated to affect immune system modulation. The freshwater species of fish, Lepomis macrochirus (bluegill), was employed to investigate the effects of a 14-day dietary exposure to PAH including 2-aminoanthracene (2-AA), 2-methylnaphthalene (2-MN), and 9,10-dimethylanthracene (9,10-DMA) and a mixture of these 3 compounds at a total dose of 3.1 ± 0.
