Short summary
We present a comparison between concentrations of dissolved trace metals in pairs of total suspended particulate (TSP) and fog samples collected in Henties Bay, Namibia, during the AErosols, Radiation and CLOuds in southern Africa (AEROCLO-sA) field campaign. We found enhanced concentrations of dissolved metals in fog samples, which we attributed to metal–ligand complex formation in the early stages of particle activation into droplets that can then remain in a kinetically stable form in fog or lead to the formation of colloidal nanoparticles.
We present a comparison between concentrations of dissolved trace metals in pairs of total...
