Distribution and transfer of organochlorines in Adelie penguins (Pygoscelis adeliae) in a breeding season
PCBs and p, p'-DDE were analysed in the subcutaneous fat (SCF), abdominal fat (AF), muscle, liver, bone, brain and an egg sample of Adelie penguins collected from Antarctica during the breeding season of 1981. PCBs and DDE were largely retained in the fat-rich tissues of Adelie penguins. With a...
