The value
of the information in Table IV is
limited by the amount and the reliability of the data.
The lack of information on the presence of elements of
fission products,
in a compilation by Vinogradov (1953) of
data on the chemical composition of fish,
is a good indi-
cation that little work has been done on these elements.
Fukai and Meinke (1959) in a more recent publication, have
reviewed the literature for data relative to the occurrence
of trace elements in sea water and marine organisms including the soft parts of fishes.
The information about trace
elements in fish was either meager,
reliability,
or nonexistent.

From these
it now appears that,
"...for any given chemical element there will eventually
be found at least one plankton species capable of spectacu-
larly concentrating it."
This is of significance to the
consideration of trace elements in fish because many plankton organisms are preyed upon by fishes and therefore fish
may have available to them trace elements in a concentrated
