To constrain their impact, we investigated primary aerosols generated by a sea-spray generator chamber using surface water samples from rivers, estuaries, and seas that were collected along salinity gradients in two temperate Korean coastal systems and one Arctic coastal system. Salinity values showed an increasing trend along the river–estuary–coastal water transition, indicating the lowest amount of inorganic salts in the river but the highest amount in the sea. In river samples, the lowest number concentration of primary aerosol particles (1.01 × 103 cm−3) was observed at the highest OM content, suggesting that low salinity controls aerosol production. Moreover, the number concentration of primary aerosols increased drastically in estuarine (1.13 × 104 cm−3) and seawater (1.35 × 104 cm−3) samples as the OM content decreased. Our results indicate that inorganic salts associated with increasing salinity play a much larger role than OM in aerosol production in river-dominated coastal systems. Laboratory studies using NaCl solution supported the conclusion that inorganic salt is a critical factor in modulating the particles produced from river water and seawater. Accordingly, this study highlights that inorganic salts are a critical factor in modulating the production of primary marine aerosols This work was supported by grants from the Korean Government (MSIT) (NRF-2021M1A5A1065425) (KOPRI-PN21011) and from the Korean Government (MSIT) (NRF-2016R1A2B3015388) (KOPRI-PN19100) With the institutional support of the ‘Severo Ochoa Centre of Excellence’ accreditation (CEX2019-000928-S) Peer reviewed 2022-01-31T11:01:08Z 2022-01-31T11:01:08Z 2022-02 artículo http://purl.org/coar/resource_type/c_6501 Science of the Total Environment 807(Part.2): 150866 (2022) 0048-9697 CEX2019-000928-S http://hdl.handle.net/10261/259246 10.1016/j.scitotenv.2021.150866 1879-1026 http://dx.doi.org/10.13039/501100011033 en Publisher's version https://doi.org/10.1016/j.scitotenv.2021.150866 Sí open Elsevier
