Induction of EROD activity in European eel (Anguilla anguilla) experimentally exposed to B(a)P and βNP
The induction of liver ethoxyresorufin O-deethylase (EROD) activity was investigated in the European eel, Anguilla anguilla, collected from a Mediterranean brackish environment and experimentally exposed to benzo[a]pyrene (B[a]P) and h-naphthoflavone (BNF). Eels were injected intraperitoneally at in...
