  1. 1. Secondary Organic Aerosols: Composition, Gas-to-Particle Partitioning and Physical Properties

    Författare :Anna Lutz; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :gas to particle conversion; volatility; secondary organic aerosols; FIGAERO; CIMS; monoterpenes; isoprene; SOA; BVOC;

    Sammanfattning : Atmospheric aerosols influence our climate and air quality. Aerosol particles in the atmosphere are transformed through many different physical and chemical reactions. A substantial fraction of the particles in the atmosphere are of secondary origin, formed as a result of gas to particle conversion. LÄS MER

  2. 2. Characterisation of PFASs and Organofluorine in Freshwater Environments : Transfer from water to land via emergent aquatic insects

    Författare :Alina Koch; Thanh Wang; Micael Jonsson; Leo W. Y. Yeung; Anna Kärrman; Lutz Ahrens; Jonathan Martin; Örebro universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; PFASs; riparian zone; emergent aquatic insects; terrestrial consumers; stable isotopes; organofluorine mass balance; AFFF; point sources;

    Sammanfattning : Per- and polyfluoroalkyl substances (PFASs) are anthropogenic contaminants of emerging concern, because many are highly persistent to degradation and have been linked to adverse effects in humans as well as their ubiquitous spread in aquatic environments. This thesis investigated distribution of PFASs and organofluorine in freshwater environments impacted by PFAS point sources. LÄS MER
