Description/Abstract:
TRANSURANIC CONCENTRATIONS IN REEF AND PELAGIC FISH FROM THE MARSHALL ISLANDS. CONCENTRATIONS OF PLUTONIUM-239+240 ARE REPORTED IN TISSUES OF SEVERAL SPECIES OF REEF AND PELAGIC FISH CAUGHT AT 14 DIFFERENT A TOLLS IN THE NORTHERN MARSHALL ISLANDS. SEVERAL REGULARITIES THAT ARE SPECIES DEPENDENT ARE EVIDENT IN THE DISTRIBUTION OF PLUTONIUM-239+2 40 AMONG DIFFERENT BODY TISSUES. CONCENTRATIONS IN LIVER ALWAYS EXCEE DED THOSE IN BONE AND CONCENTRATIONS WERE LOWEST IN THE MUSCLE OF ALL FISH ANALYSED. A PROGRESSIVE DISCRIMINATION AGAINST PLUTONIUM-239+24 0 WAS OBSERVED AT SUCCESSIVE TROPHIC LEVELS AT ALL ATOLLS EXCEPT BIKIN I AND ENEWETAK, WHERE IT WAS DIFFICULT TO CONCLUDE IF ANY REAL DIFFERE NCE EXISTS BETWEEN THE AVERAGE CONCENTRATION FACTOR FOR PLUTONIUM-239+ 240 AMONG ALL FISH, WHICH INCLUDE BOTTOM-FEEDING AND GRAZING HERBIVORE S, BOTTOM-FEEDING CARNIVORES AND PELAGIC CARNIVORES FROM DIFFERENT ATO LL LOCATIONS. THE AVERAGE CONCENTRATION OF PLUTONIUM-239+240 IN THE M USCLE OF SURGEONFISH FROM BIKINI AND ENEWETAK WAS NOT SIGNIFICANTLY DI FFERENT FROM THE AVERAGE CONCENTRATIONS DETERMINED IN THESE FISH AT TH E OTHER LESSER CONTAMINATED ATOLLS. CONCENTRATIONS AMONG ALL THIRD, F OURTH, AND FIFTH TROPHIC LEVEL SPECIES ARE HIGHEST AT BIKINI WHERE HIG HER ENVIRONMENTAL CONCENTRATIONS ARE FOUND. THE REASONS FOR THE ANOMA LOUSLY LOW CONCENTRATIONS IN HERBIVORES FROM BIKINI AND ENEWETAK ARE N OT KNOWN.
