Species-Specific Metabolism of Naphthalene and Phenanthrene in 3 Species of Marine Teleosts Exposed to Deepwater Horizon Crude Oil
The 2 most abundant polycyclic aromatic hydrocarbons (PAHs) measured in Deepwater Horizon crude oil, naphthalene and phenanthrene, and their associated homologs have both been shown to be acutely toxic in fish. Although fish have a relatively high metabolic capacity for PAHs, hydroxylated PAH (OH-PA...
