Concentrations of mono-, di-, and trimethylamine (MMA, DMA, and TMA, respectively), and their precursors, the quarternary amines glycine betaine and choline, were enhanced in sympagic seawater samples relative to ice-devoid pelagic ones, suggesting the microbiota of sea ice and sea ice-influenced ocean is a major source of these compounds. Primary sea-spray aerosol particles artificially generated by bubbling seawater samples were investigated by aerosol time-of-flight mass spectrometry (ATOFMS) of single particles; their mixing state indicated that alkylamines were aerosolized with sea spray from dissolved and particulate organic nitrogen pools. Despite this unequivocal sea spray-associated source of alkylamines, ATOFMS analyses of ambient aerosols in the sympagic region indicated that the majority (75-89%) of aerosol alkylamines were of secondary origin, that is, incorporated into the aerosol after gaseous air-sea exchange. These findings show that sympagic seawater properties are a source of alkylamines influencing the biogenic aerosol fluxed from the ocean into the boundary layer; these organic nitrogen compounds should be considered when assessing secondary aerosol formation processes in Antarctica The study was supported by the Spanish Ministry of Economy through project BIOeNUC (CGL2013-49020-R), PI-ICE (CTM2017-89117-R) and the Ramon y Cajal fellowship (RYC-2012-11922), and by the EU though the FP7-PEOPLE-2013-IOF programme (Project number 624680, MANU - Marine Aerosol NUcleations), all to MD, and PEGASO (CTM2012-37615) to RS Peer Reviewed 2019-06-26T08:49:15Z 2019-06-26T08:49:15Z 2019-04 2019-06-26T08:49:15Z artículo http://purl.org/coar/resource_type/c_6501 doi: 10.1021/acsearthspacechem.9b00028 e-issn: 2472-3452 ACS Earth and Space Chemistry 3: 854-862 (2019) http://hdl.handle.net/10261/184851 10.1021/acsearthspacechem.9b00028 http://dx.doi.org/10.13039/501100003329 http://dx.doi.org/10.13039/501100000780 http://dx.doi.org/10.13039/501100011033 #PLACEHOLDER_PARENT_METADATA_VALUE# #PLACEHOLDER_PARENT_METADATA_VALUE# #PLACEHOLDER_PARENT_METADATA_VALUE# info:eu-repo/grantAgreement/MINECO/Plan Estatal de Investigación Científica y Técnica y de Innovación 2013-2016/CGL2013-49020-R CTM2017-89117-R/AEI/10.13039/501100011033 info:eu-repo/grantAgreement/AEI/Plan Estatal de Investigación Científica y Técnica y de Innovación 2017-2020/CTM2017-89117-R Postprint https://dx.doi.org/10.1021/acsearthspacechem.9b00028 Sí open American Chemical Society |
