| 内容記述 | The species of mollusks have been used as an important food item and caught in large quantity off the coast of Japan. The mollusks have unique physiological properties and the elemental composition different from those of fishes as observed in the blood constituents. Much higher concentrations of metal element such as cupper, zinc, cadmium and so on have been often reported for squids and shellfishes than other organisms. The present study reports the results of gamma spectrometry analyses for two species of gastropods (Buccinum isaotakii and Buccinum striatissimum) inhabiting on the sea bottom at the depth of some hundreds meters off the coast and for squids (Todarodes pacificus and Thysanoteuthis rhombus) landed at several fishing ports in Japan. It would be noted that Ag-108m (half-life time: 418.21y) was commonly detected for the viscera of both gastropods and squids usually at the radioactivity level higher than Cs-137. A discussion on the origin and mass balance of Ag-108m in the sea was made on the basis of the data on its specific activity, which was derived from the data on stable Ag for the samples of interest obtained by analyses using ICP-AES. Special attention was directed to the efficacy and applicability of the mollusks having an affinity for the element to the environmental monitoring as indices. | |||||
