6. Haloacetates in precipitation
Sammanfattning : Haloacetates are a group of fluorinated, chlorinated and brominated organic compounds that pose a potential threat to the environment, because they are present in relatively high concentrations in precipitation and they are toxic to plants. At the time the research described in this thesis was begun, it had been suggested that atmospheric degradation of chlorinated solvents and CFC replacements were responsible for the presence of haloacetates in precipitation in populous regions.

7. Seasonal variation of road runoff in cold climate
Sammanfattning : The main objective of this thesis was to characterize and study the behaviour and transport of pollutants, i.e., suspended solids, particles and heavy metals, in road runoff from a small urban catchment during snowmelt and rainfall. LÄS MER
8. Mineral dissolution from molecular to field scale
Sammanfattning : Mineral reactivity contributes to the global biogeochemical cycling of elements. CO2is consumed during the chemical weathering of many silicates and during formation of carbonates in the oceans. LÄS MER
9. Disturbance regimes in dry sandy grasslands – past, present and future
Sammanfattning : A number of sandy grassland habitats of interest for biodiversity conservation can be found in Europe. One such habitat is the threatened xeric sand calcareous grassland, which is home to a large number of endangered species. LÄS MER
10. Droplet growth in atmospheric turbulence : A direct numerical simulation study
Sammanfattning : This Ph.D. thesis examines the challenging problem of how turbulence affects the growth of cloud droplets in warm clouds. Droplets grow by either condensation or collision. LÄS MER
