M. Yamazaki et al., SILVER AND OTHER TRACE-ELEMENTS IN A FRESH-WATER FISH, CARASIUS-AURATUS-LANGSDORFII, FROM THE ASAKAWA RIVER IN TOKYO, JAPAN, Environmental pollution, 94(1), 1996, pp. 83-90
The concentrations of silver (Ag) in a typical freshwater fish in Japa
n, Carasius auratus langsdorfii, and some other species have been dete
rmined to examine the Ag-contamination of fish and to specify the Ag a
ccumulating species and part. They were dissected roughly into four pa
rts, and analyzed by an instrumental neutron activation analysis. It w
as found that Ag was accumulated in the samples from the Asakawa River
, and that the Ag concentration in the entrails of C. auratus langsdor
fii reached 12 mu g g(-1). The analysis of a C. auratus langsdorfii, w
hich was dissected into 13 individual organs, showed that the Ag was a
ccumulated highly in the liver, followed by the gallbladder and kidney
. The inter-species and inter-part distributions of other trace elemen
ts have also been studied. Copyright (C) 1996 Elsevier Science Ltd.
