Description/Abstract:
SOME EFFECTS OF THE BIOLOGICAL SPECIFICITY OF ZINC ON THE DISTRIBUTION OF FALLOUT ZINC-65 IN THE LAGOON OF RANGELAP ATOLL WERE STUDIED BY ME ANS OF RADIOMETRIC AND CHEMICAL ANALYSES OF FISH TISSUES. STABLE ZINC, AFTER CHROMATOGRAPHIC SEPARATION FROM THE FIRST SERIES TRANSITION ELE MENTS, WAS DETERMINED BY A COLORIMETRIC METHOD USING DITHIZONE. ZINC-6 5 WAS DETERMINED BY GAMMA SPECTROMETRY. FALLOUT RADIOZINC APPARENTLY B CAME ASSOCIATED WITH A PARTICULATE PHASE IN THE WATER OFTHE LAGOON. BI OLOGICAL UPTAKE AND RETENTION IN THE ECOLOGICAL SYSTEMS OF THE LAGOON PREVENTED ITS FLUSHING OUT OF THE ATOLL IN THE EXCHANGE OF WATER BETWE WEEN THE LAGOON AND THE OCEAN. THE INGESTION, BY HETEROTROPHS, OF PART ICULATE MATTER IN THE WATER FAVORED THE CONCENTRATION OF RADIOZINC IN CARNIVOROURS FISH. EYES WERE SHOWN TO BE USEFUL AND CONVENIENT ORGANS FOR DETERMINING THE RELATIVE ACCUMULATION OF RADIOZINC BY DIFFERENT FI SH.
