1. Submicrometre aerosol emissions from sea spray and road traffic
Sammanfattning : The uncertainty of the climate and health effects of aerosols is still large, one important reason being lack of knowledge of the primary emissions. This thesis combines laboratory and field experiments, and process modelling in an effort to better quantify the submicrometre aerosol emissions and to understand some of the processes in the atmosphere.

2. Primary Marine Aerosol : Validation of sea spray source functions using observations and transport modeling
Sammanfattning : Sea spray aerosols (SSA) are an important part of the climate system through their effects on the global radiative budget, both directly as scatterers and absorbers of solar and terrestrial radiation, and indirectly as cloud condensation nuclei (CCN) influencing cloud formation, lifetime and precipitation. In terms of their global mass, SSA is the largest source and has the largest uncertainty of all aerosols. LÄS MER
3. Factors influencing emission fluxes and bacterial enrichment in sea spray aerosols : Insights from laboratory and field studies
Sammanfattning : Sea spray aerosol (SSA) is one of the major natural aerosol sources and is produced when wave breaking entrains air into ocean surface water, which subsequently breaks up into bubbles. These bubbles rise to the surface and can scavenge biogenic material. LÄS MER
4. Primary Marine Aerosol Production : Studies using bubble-bursting experiments
Sammanfattning : Aerosol particles affect the Earth’s climate, although their impact is associated with large uncertainties. Primary marine aerosol represents a significant fraction of the global aerosol budget considering the Earth’s 70-percentage coverage by oceans. LÄS MER
5. Transport of perfluoroalkyl acids from the ocean to the atmosphere via sea spray aerosol
Sammanfattning : Perfluoroalkyl acids (PFAAs) are a subgroup of per- and polyfluoroalkyl substances (PFAS) that have been widely used in commercial and industrial applications. PFAAs are very persistent in the environment and some can bioaccumulate and have adverse health effects on human health. LÄS MER
