Persistent organic pollutants and enzyme activities in European eel (Anguilla anguilla) from Orbetello lagoon
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. Levels of POPs, including seven polychlorobiphenyls (PCBs) (known as markers of Aroclor 1260), three coplanar PCBs, ΣDDT (op-DDD...
