Bestimmung von schwermetallen und selen in fischen aus oberösterreichischen gewässern—teil 2: Blei, cadmium, scandium, chrom, cobalt, eisen, zink und selen

Abstract

119 samples of fish, which were caught in September 1974 in Upper Austrian waters, were analysed for zinc, iron, cobalt, chromium, scandium and selenium by neutron activation analyses and for lead and cadmium by atomic absorption spectrometry. The concentration values found for Zn ranged between 13 and 44 ppm, for Fe between 11 and 111 ppm, for Co between 0·01 and 0·40 ppm, for Cr between 0·02 and 0·21 ppm, for Pb between 0·01 and 0·28 ppm, with a single exception, for Cd 0·01 and 0·13 ppm and for Se between 0·62 and 2·02 ppm. The concentration of Sc was below the detection limit (0·5 pptm) for all fish samples analysed.
