摘 要: | The effects of phenanthrene (Phe) on hepatosomatic index (HSI) and hepatic enzymatic activities in hybrid tilapia (Oreochromis
niloticus O. aureus ) were investigated via the static freshwater exposure at dosage of 50, 100, and 400 g/L for 4–14 d.
Compared with the control group, HSI was significantly decreased (P < 0.05) at 400 g/L at day 14. Increased enzymatic activities (P
< 0.05) were observed for catalase (CAT), glutathione peroxidase (GPx) and superoxide dismutase (SOD) at either 100 or 400 g/L at
day 8 and 14, as well as for CAT at 50 g/L at day 14, except for GPx at 400 g/L at day 8. Ethoxyresorufin O-deethylase (EROD)
activity was significantly increased (P < 0.05) at all dosage at day 4 as well as at 50 g/L at day 8, but significantly decreased at either
100 or 400 g/L at day 14 (P < 0.05). Glutathione-S-transferase (GST) activity was not a ected. The results suggest that CAT, GPx,
SOD and EROD, as well as HSI in tilapia may be used as the biomarkers or indexes for evaluating or monitoring the pollution of
polycyclic aromatic hydrocarbons (PAHs) such as Phe.
