Variations of organochlorine residues with age and sex in Antarctic minke whale
Concentrations of polychlorinated biphenyls (PCBs) and p, p′-DDE were determined in the blubber of Antarctic minke whale collected during the 1984-1985 whaling season and found to be in the ranges of 3.1 to 29 ng/g and 13 to 140 ng/g on wet weight basis, respectively. These values were much lower in...
