1. Iodine Isotopes (129I and 127I) in the Baltic Sea : Tracer applications & environmental impact
Abstract : 129I is a radioactive isotope (T1/2= 15.7 million years) produced through natural and anthropogenic pathways, but the anthropogenic production is presently dominating the Earth’s surface environments. READ MORE

2. Lifecycle of Black Carbon in the Arctic
Abstract : This PhD thesis investigates the atmospheric life cycle of Black Carbon (BC) in the Arctic. The Arctic region has been rapidly changing in the last decades and the role of BC aerosols in this is still uncertain. READ MORE

3. Bioaerosols and their importance for low-level Arctic clouds
Abstract : Bioaerosols are microorganisms or functional parts of them or other biological matter suspended in air. Examples are bacteria, viruses, pollen, spores, or smaller plant debris. In the atmosphere, bioaerosols can play various functional roles, such as facilitating the spread of genetic material. READ MORE

4. Stable and radiogenic isotopes as tracers for geochemical processes in mineralogically-complex mine waste environments : Insights from 13C, 2H, 18O, 34S and 87Sr/86Sr
Abstract : Mining and its related activities generate large volumes of mine wastes such as tailings that can have negative environmental implications. One of such mine wastes of potential environmental concern is the historical Yxsjöberg Cu-W-F skarn tailings in Sweden, which encompasses a complex mineralogy including sulphides, carbonates, silicates, oxides / wolframite and halides.

5. Isotopic and Molecular Characterization of Incomplete Combustion Products in sub-Saharan Africa
Abstract : Sub-Saharan Africa (SSA) is a global hotspot for incomplete combustion emissions from large-scale savanna fires, agricultural burning and growing city emissions. However, air pollution is understudied in the SSA region, resulting in a gap in the scientific understanding of regional emissions, source contributions, and impacts of air pollutants on regional climate and health.
