Abstract
The zinc, iron, cobalt, cesium and scandium contents of the meat and edible viscera of Japanese cattle, swine and chicken were determined by non-destructive neutron activation analysis. The zinc contents were as follows: from 43.9 to 79.3ppm for beef, from 19.1 to 45.0ppm for cattle edible viscera, from 20.4 to 114.9ppm for pork from 39.3 to 94.7ppm for swine edible viscera, from 3.5 to 10.8ppm for chicken, and from 7.5 to 21.8ppm for chicken edible viscera. The iron contents were: from 10.7 to 24.9ppm for beef, from 4.0 to 41.1ppm for cattle edible viscera, from 12.5 to 27.5ppm for pork, from 12.5 to 325.6ppm for swine edible viscera, from 2.3 to 5.5ppm for chicken, and from 6.7 to 47.5ppm for chicken edible viscera. The contents of cobalt, cesium and scandium detected were in the order of ppb ar not detectable. The correlations between iron content and cobalt content, and between iron content and zinc content were investigated.
