Airborne Nanoplastics, Sea Spray, and Their Impact on Climate

PhD defense, Tuesday, 3 December 2024. Eva R. Kjærgaard

Eva Rosendal Kjærgaard

During her PhD studies, Eva R. Kjærgaard explored the transfer and properties of nanoplastic particles from water to air by bubble bursting. She also analyzed seawater from Ajstrup Beach to examine its ice nucleating properties using an instrument she helped construct and test. Furthermore, her research investigated how seawater salinity, temperature, and chemical composition change the generation of particles from seawater.
These findings contribute to our understanding of how plastics and ice nucleating particles are emitted from water and what factors control the generation of particles from seawater. Thus, providing valuable insights into the factors influencing airborne nanoplastic particle and sea spray aerosol generation and their broader environmental impact.

The PhD study was completed at Department of Chemistry, Faculty of Natural Sciences, Aarhus University.

This summary was prepared by the PhD student.
