Embryotoxicity of retene in cotreatment with 2-aminoanthracene, a cytochrome P4501A inhibitor, in rainbow trout (Oncorhynchus mykiss).

Environmentally relevant mixtures of polycyclic aromatic hydrocarbons (PAHs; e.g., crude oils) are often rich in alkyl-PAHs, such as retene (7-isopropyl-1-methylphenanthrene), which produce dioxin-like toxicity in fish embryos.
