Estrogenic Evaluation and Organochlorine Identification in Blubber of North Sea Harbour Porpoise (Phocoena phocoena) Stranded on the North Sea Coast

Table 3

Gender, length (cm), weight (kg), blubber thickness (cm), and blubber levels (g/kg) of 13 organochlorine compounds of 12 North Sea harbour porpoise individuals. Chemicals were divided in three groups and the sum of concentrations for each group is presented for the different samples.
