York University Departments of Bisleey and Environmental Medicine visited the atzll and rallected water, plankton and beach ceral samples te etudy the distribution of foraminifera among the islands ef Enewetak and cther yearby atclie. Of the specimens collected, 22 samples of beach materiel fron the nighly contaminated northern islands of Enewetak remained intact and were available fer study. Q@nalyses of the radionuclide concentrations of these samples have previded interesting information regarding the levels af contamination that existed on Enewetak at that time.

Trese cata and information on the particulate forms are ATBINZES in coajumction with antillary chemicel ard meteralcgical data tz cra. inferences about scurces, fluxes, and chemical steciations. While the Figrer molecular veicht lipid biomarker camponents are exclusively fecyeetrial, the orosnic carson in rain may be derivec from atmeepheric trrangformaticcs of tarrestrisi cerbon. Distinctively marine compenerts are needy acesent. Cemperisen cf the scavenging ratios of the crganic cifosaents in rain vs. those fer clays reveals that the zlkanaic acids end the tigher melecctlar weight alkanols sebave ae etsentially particulate meteriais, wharaas lower alkano:s and mest hydrecarbens shew much higher scavenging ratios, prebably due te the involvement of a gasecus phase or sanplirg artifact. Vaperization in the atmosphere and scaveging cf a gas phase would iead te higher ecaveging ratios; vapcrization during sampling would give low aeresal concentrations and high gas-phase concentrations, leacing te high scavening ratios. The major fluxes at Enewetak result from r2in rather than dry deposition, and extrapolating the measured values toa meaningful annual averages requires acjustment for seasonally varying source intensity and rain dynamics. Aeresol data for ather seasons and ether substances are used te correct for scurce-strength intensity verietionz, and a /sup 219/Pb/arganic compound cerrelaticn is established and extrapclated to adjust fer rainfali volume effects.
