Abstract:

Proximate composition and the distribution of cadmium in different organs of Pteria penguin were determined.
The results showed that the contents of crude protein, crude fat, total ash and total sugar were 87.0%, 3.73%, 6.52% and
6.65% on a dry basis, respectively. In the proximate composition of Pteria penguin, the cadmium was distributed mainly
in the crude protein (86.91%) with a minor quantity in the crude polysaccharides (10.63%) and crude fat (0.41%). As for
the different organs of Pteria penguin, the cadmium was mainly distributed in the visceral mass (35.6%), followed by the
closing adductor muscle (28.2%) and mantle (18.2%), with the remaining distributed in the gills (9.5%) and foot (6.5%).
