Effect of exposure to polycyclic aromatic hydrocarbons on Na(+)-K(+)-ATPase in juvenile gilthead seabream Sparus aurata.

In this study, the effects of exposure to pyrene, fluorene and a mixture of selected polycyclic aromatic hydrocarbons (PAH) upon branchial Na (+)/K (+)-ATPase was investigated in juvenile seabream Sparus aurata in a 96 h in vivo experiment. No significant effect was found, and thus it was concluded that branchial Na(+)/K (+)-ATPase is probably not affected by PAH.
