Assessment of trophic transfer of benzo( a )pyrene genotoxicity from the post-larval pink shrimp F. brasiliensis to the juvenile Florida pompano T. carolinus

Highlights ► The genotoxicity of benzo( a )pyrene (BaP) was investigated in a one-step predator–prey relationship with the trophic-related marine species. ► BaP body burden increased in preys exposed to different PAH concentrations, as well as the BaP bile metabolites of fish that fed upon those pre...

Description
Summary:Highlights ► The genotoxicity of benzo( a )pyrene (BaP) was investigated in a one-step predator–prey relationship with the trophic-related marine species. ► BaP body burden increased in preys exposed to different PAH concentrations, as well as the BaP bile metabolites of fish that fed upon those preys. ► Comet and ENAs assays indicated significant increase on erythrocyte DNA damage of predators. ► The trophic route of BaP genotoxicity and the PAH biotransformation as the inducing mechanism for the DNA damages are discussed.
