 Sea salt aerosols are mainly constituted of sodium chloride (NaCl), but other chemical ions which are common in sea water, such as K+, Mg2+, Ca2+, SO42− and so on, can also be found.A recent study revealed that sea salt aerosols also contain a substantial amount of organic matter.Mostly, organic materials are internally mixed due to the drying of air bubbles at the organic-rich sea surface.
