PBDE levels in the blubber of Cuvier’s beaked whale in the three age classes: juvenile (light blue), subadult (medium blue) and adult (dark blue). (a) Boxplots showing ΣPBDE concentrations (mg/kg lipid weight) in blubber of Cuvier’s beaked whale of juvenile (n = 4), subadult male (n = 8) and adult male (n = 6). (b) The mean values of the individual PBDE congener for all 27 PBDE congeners, in the age classes. Error bars represent standard errors (SE).
