Research project Impacts of sea spray aerosol transport of perfluoroalkyl acids (PFAAs) on coastal regions

In this project, we plan to: (1) measure PFAAs in air on the Danish and Swedish coasts using high-volume air samplers and correlate PFAA air concentrations to SSA tracer ions measured in the same samples, (2) measure PFAAs in different aerosol size fractions near the coast using a cascade impactor, (3)  measure wet and dry deposition of PFAAs using an automatic wet/dry deposition sampler, as well as levels of PFAAs in surface environmental media along a gradient from the sea inland, (4) model SSA emission in the surf zone and SSA transport and deposition to land to explain our empirical data, and (5) disseminate the results to relevant stakeholders.
