Evidence for polynuclear aromatic hydrocarbons in the diet of bottom-feeding fish

Diagnostic criteria for proliferative hepatic lesions in brown bullhead Ameiurus nebulosus

“…These criteria should assist fish pathologists in describing and categorizing proliferative liver lesions from brown bullhead. A key indicator species for AOC is the brown bullhead Ameiurus nebulosus (IJC 1987), because this is a bottom-dwelling fish with a limited home range and is known to take up contaminants from food and sediments (Maccubbin et al 1985, Baumann 1989, Baumann et al 1991, 1996, Smith et al 1994. Both liver (Harshbarger & Clark 1990, Baumann & Harshbarger 1995, Pinkney et al 2001) and skin (Black 1983, Smith et al 1989, Bowser et al 1991, Poulet et al 1994) neoplasms have been associated with exposure to polynuclear aromatic hydrocarbons (PAH) and other contaminants.…”

Accumulation and food chain transfer of fluoranthene and benzo[a]pyrene in Chironomus riparius and Lepomis macrochirus

“…Polycyclic aromatic hydrocarbons have been identified in stomach contents of bottom-feeding fish, indicating potential dietary uptake of these compounds (Maccubbin et al 1985;Malins etal. 1987).…”

Key Environmental Human Health Issues in the Great Lakes and St. Lawrence River Basins

“…Wildlife investigators report that neoplastic tumors in some Great Lakes bottom-dwelling fish (e.g., brown bullheads) are associated with high levels of PAHs (Baumann et al, 1982;Maccubbin et al, 1985;Price and Weseloh, 1986). Other toxic effects include enlarged thyroid glands in fish and suppression of T-cell-mediated immunity following prenatal exposure to organochlorines in herring gull and Caspian terns (Leatherland, 1992;Grasman et al, 1996).…”
