Mass spectrometric analyses of low levels of global fallout plutonium separated from Atlantic marine samples have differentiated fallout 239Pu and 240Pu in aquatic samples for the first time. The results show no single characteristic 240Pu/239Pu ratio in marine samples; the observed range is from 0.11 to 0.24 on an atom basis. There are indications that differences exist in the chemical or physical form of plutonium from atmospheric fallout in Atlantic surface water and that selective concentration in surface organisms is occurring. No single 240Pu/239Pu value is found in pelagic sediments collected from different depths and locations. Discounting sources other than fallout, our results show that the plutonium deposited at any given time since atmospheric testing began may have carried a unique 240Pu/239Pu tag. This label may be extremely useful to trace fallout plutonium through biogeochemical cycles.
