These measurements were made to determine whether or not a significant flux of these radionuclides from the sea surface to the atmosphere could occur. They also introduce a method for treating chemical data that they believe may be useful in determining the origin of the trace-metal enrichments often observed in the microlayer. The authors have shown that the sea-surface microlayer is enriched in <sup>210</sup> Pb and <sup>210</sup> Po. Their interpretation of the data suggests that a significant fraction of the enrichment is maintained by concentration from the bulk surface seawater. In the open ocean this concentration process results in preferential transport of <sup>210</sup> Po to the air-sea interface. In coastal environments there may be a lesser degree of chemical fractionation. Because coastal waters often have <sup>210</sup> Po/<sup>210</sup> Pb activity ratios <1, the sea surface is, in either case, a potential source of aerosols with <sup>210</sup> Po/<sup>210</sup> Pb >1 as suggested by Turekian et al. The natural flux of microlayer material from the sea to the atmosphere, however, is not known. Note finally that analytical treatment of the microlayer enrichments was limited because only two elements were used. Further analysis by a multi-element approach is suggested.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Enrichment of <sup>210</sup> Pb and <sup>210</sup> Po in the sea-surface microlayer","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-14 01:31:16.485049","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":1998,"MonPub":null,"DateUpdate":"2014-08-18","DateCreate":"2008-06-17","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:A1980JL21100037","VABBcode":null,"OpenAcc":1,"DOI":"10.1038/284332a0"},"refs":null,"anarec":{"AnaID":123080,"PubliDate":1998,"Pagination":"332-334","XtraPublOfAnaID":null,"ISBN":null,"Volume":"284","Issue":"5754","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43431,"SerRR":"Nature: International Weekly Journal of Science.
