  1. 1. On the Determination of Reactive Compounds in Aerosols

    Författare :Mårten Spanne; Ergonomi och aerosolteknologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Environmental technology; industrial hygiene; isocyanates; particles; sampling; aerosols; pollution control; Miljöteknik; kontroll av utsläpp;

    Sammanfattning : Many sources of airborne contaminants have always been present in various work environments. With the development of thermosetting plastic systems, the use of reactive chemical compounds was greatly increased and thus also the risk of exposure to reactive and potentially hazardous compounds.

  3. 2. Chemical composition of Arctic aerosols and their link to clouds

    Författare :Yvette Gramlich; Claudia Mohr; Paul Zieger; Ilona Riipinen; Ulrich Pöschl; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Arctic; aerosols; cloud residuals; mass spectrometry; biomass burning; Environmental Sciences; miljövetenskap;

    Sammanfattning : The Arctic is a place particularly vulnerable to climate change, warming at an accelerated rate compared to the rest of the Earth. In this remote environment, the atmosphere, the ocean, the ice, and the land are all interlinked and are shaping a very complex system. LÄS MER

  4. 3. Multiple perspectives on absorbing aerosols over the northern Indian Ocean and Asia

    Författare :Friederike Höpner; Frida Bender; Annica Ekman; Heike Wex; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; aerosols; black carbon; air pollution; South Asia; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Sammanfattning : Aerosol particles in the atmosphere scatter and absorb solar radiation, and thereby affect the Earth's energy budget, but the magnitude of the overall radiative effect due to aerosol-radiation interactions is uncertain. In particular, the impact of absorbing aerosol particles, mainly black carbon (BC), organic carbon and dust, is not completely understood. LÄS MER

  5. 4. Properties and Origin of Arctic Aerosols

    Författare :Ann-Christine Engvall; Jörg Gumbel; Frode Stordal; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Arctic aerosols; Arctic troposphere; air-mass transport; Atmosphere and hydrosphere sciences; Atmosfärs- och hydrosfärsvetenskap; atmosfärvetenskap; Atmospheric Sciences;

    Sammanfattning : The present thesis deals with the origin and physics of aerosols in the Arctic atmosphere. These show a large annual variability due to changes of the photochemical and cloud processes as well as of the synoptic-scale atmospheric pressure patterns. LÄS MER
