Ecotoxicological status of seven sperm whales (Physeter macrocephalus) stranded along the Adriatic coast of Southern Italy
In December 2009 seven male sperm whales (Physeter macrocephalus) stranded along the Adriatic coast of Southern Italy. Genetic and photo-identification data indicated that these specimens belonged to the Mediterranean Sea population. Complete necropsies were performed on the three best preserved ani...

In December 2009 seven male sperm whales (Physeter macrocephalus) stranded along the Adriatic coast of Southern Italy.

Blubber and muscle samples were collected from all seven specimens for contaminants analysis (DDTs, PCBs and PAHs) and biomarker responses (CYP1A1 and CYP2B) were evaluated from the three better preserved animals using western blot analysis.
