  2. 11. Atmospheric Production and Transport of Cosmogenic 7Be and 10Be

    Author : Abdulhadi Kulan; Ala Aldahan; Göran Possnert; Raimund Muscheler; Uppsala universitet; []
    Keywords : Earth sciences; Aerosols; Atmosphere; Cosmogenic Be-7 and Be-10; Cs-137; Clouds; Sweden; Europe; Geovetenskap;

    Abstract : This thesis deals with the atmospheric distribution of the cosmogenic isotopes 7Be (half-life 53 days) and 10Be (half-life 1.51 million years) as well as the anthropogenic isotope 137Cs (half-life 30 years) in aerosols and precipitation. READ MORE

  4. 12. Development of molecular techniques for fungal diagnostic research

    Author : Qing-Yin Zeng; Åsa Rasmuson-Lestander; Xiao-Ru Wang; Aino Nevalainen; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; Fungi; DNA markers; Aerosols; Detection and quantification; Environmental monitoring; Molekylärbiologi; Molecular biology; Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Abstract : Fungi are present everywhere in indoor and outdoor environments. Many fungi are toxigenic or pathogenic that may cause various public health concerns. Rapid detection, quantification and characterization of fungi in living and working environments are essential for exposure risk assessment to safe guard public health. READ MORE

  5. 13. Extraction and Chromatography of targeted emission markers in atmospheric aerosols

    Author : Hafiz Abdul Azeem; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; atmospheric aerosols; emission markers; mass spectrometry; supercritical CO2; trace analysis;

    Abstract : Atmospheric aerosols are a highly complex and dynamic mixture of solid particles, liquid deplots and gases. They travel across the continents and affect global climate and human health in various ways, often negatively. One important aspect of research in atmospheric aerosols is the investigation of emissions to the atmosphere from various sources. READ MORE

  6. 14. Lifecycle of Black Carbon in the Arctic

    Author : Roxana S. Cremer; Ilona Riipinen; Peter Tunved; Sara Blichner; Hannele Korhonen; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Black Carbon; Aerosols; Arctic; lifecyle; absorption; Environmental Sciences; miljövetenskap;

    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

  7. 15. Bioaerosols and their importance for low-level Arctic clouds

    Author : Gabriel Pereira Freitas; Paul Zieger; Radovan Krejci; Kevin J. Noone; Claudia Mohr; Martin Gallagher; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Bioaerosols; Aerosols; Clouds; Arctic; Cloud Condensation Nuclei; Ice Nucleating Particles; Sea Spray Aerosol; Environmental Sciences; miljövetenskap;

    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
