Study shows very minor transport of TFA via seasalt aerosol from the oceans to land

EFCTC commissioned a study “Assessment of Possible Transport of Trifluoroacetic Acid from the Oceans to the Atmosphere” by Professor Simon L Clegg, University of East Anglia, to understand if significant quantities of TFA are transported in sea salt aerosol from the oceans, with the potential of further transport over land, in the gas phase for TFA that has been expelled from the aerosol by acidification. The study evaluated the potential for TFA to partition from aged sea salt aerosol, in the same way that hydrochloric acide (HCl) is partitioned from aged sea salt aerosol to the troposphere. There are studies published for HCl enabling a comparison to be made. This study was prompted in part by the published papers showing significant transport of longer chain PFAS from the oceans to land. See explanatory note.
