Some important behaviors of trace elements in the living body have recently been made clear. As an example some of trace elements are found in blood or enzyms and behave as a catalyst in the biochemical reactions.
The investigations on the distribution of trace elements in the bodies of sea fishes may afford some contributions to the problems on the behaviors of trace elements in the living bodies.
In this paper the distributions of Zn, Cu and Pb in the sea fishes as deep-sea fishes,
Katsuwonus pelamis and
Monocentris japonica are reported.
These three elements were isolated by the ion exchange resin from the solution obtained by dissolving the ashes of fishes in HNO
3; and also these three were simultaneously determined by the polarographic method.
In the bodies of these fishes, Zn is most aboundant, Cu is secondarily and Pb least.
Generally Zn is rich in flesh but poor in bones. Cu is rich in deep-sea fishes such as
Chlorophthalmus albatrossis albatrossis (Aome-eso) and
Synagrops japonica (Sumikuiuo) and Pb is most rich in the gills and the heart of
Kastutvonus pelamis.
The scale of
Monocentris japonica, and the stomach and heart of
Katsuwonus pelamis contain Cu more than the other parts respectively.
