Primary and Secondary Organic Marine Aerosol and Oceanic Biological Activity: Recent Results and New Perspectives for Future Studies

Table 3

Alkylammonium ions aerosol concentration range (in brackets) and median value (when available) reported in the literature for the marine environment. All concentrations are in ng m^-3. All data refer to submicron particles except for Müller et al. [51], whose size cut was 0.14–0.42 𝜇m, and Gorzelska and Galloway [44], who did not report any particle size information.
