  1. 1. Carbonaceous aerosols and trace metal deposition in high-latitude snow : a comparative study in Sweden and Alaska

    Master-uppsats, SLU/Dept. of Soil and Environment

    Författare :Anika Pinzner; [2019]
    Nyckelord :PM; carbon particles; pXRF; arctic; subarctic; EC OC; LAHM; PSAP; TOT; ICP-MS; filter; contamination; albedo;

    Sammanfattning : This study investigates the advantages and disadvantages of several destructive and non-destructive analytical methods that can be employed to characterize airborne par-ticulate matter (PM) deposited in seasonal snow. To this end, a comparative study was conducted on PM obtained from snowpack surveys in two Arctic/subarctic regions of Northern Sweden and Interior Alaska, USA. LÄS MER

  3. 2. Atmospheric Particles in Kermanshah, Iran

    Master-uppsats, Lunds universitet/Atomfysik; Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

    Författare :Rebecka Häggström; [2017]
    Nyckelord :aerosols; aerosol technology; SMPS; soot concentrations; dust; Iran; Kermanshah; PSAP; airborne particles; Technology and Engineering; Physics and Astronomy; Earth and Environmental Sciences;

    Sammanfattning : No measurements of airborne particles have been done in Iran previously. Starting characterization of aerosol particles in a completely new geographical area, a suitable and important measurement parameter is the aerosol particle number size distribution. This can be used to indirectly infer climate- and health effects of the particles. LÄS MER

  4. 3. The Use of Machine-to-Machine Communication in the Swedish Building Sector

    Master-uppsats, KTH/Industriell Management
