Biomarkers of Exposure and Effect in Flounder (Platichthys flesus) Exposed to Sediments of the Adriatic Sea

摘要

The modifications of several biomarkers were investigated in flounder (Platichthys flesus) when exposed in the lab- oratory to sediment samples collected from the Northern Adriatic Sea. Besides clean sand used as a control sub- Strate, fish were exposed to sediments sampled offshore The delta of the Po River, the harbour of Trieste, and from The industrial harbour of Venice (Porto Marhera). After Six days of exposure, the enzyme activities ethoxyres- Orufin-O-deethylase (EROD), UDP glucuronyltransfer- Ase (UDPGT), glutathione S-transferase (GST), Glutathione reductase (GR) and glutathione peroxidase (GPx), were assayed in fish liver.
