Persistent organic pollutants and enzyme activities in European eel (Anguilla anguilla) from Orbetello Lagoon
1 - The aim of the present study was to obtain insights into the environmental quality of Orbetello lagoon using the European eel (Anguilla anguilla) as bioindicator organism. 2 - Levels of POPs, including seven polychlorobiphenyls (PCBs) (known as markers of Aroclor 1260), three coplanar PCBs, ΣDDT...
