  2. 16. Air Pollution Dependency on Climate Variability and Source Region : Past, Current and Future Air Pollution Scenarios over Europe

    Author : Camilla Andersson; Hans-Christen Hansson; Christer Johansson; Joakim Langner; David Simpson; Peter Builtjes; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Acidification; Air Pollution; Climate Change; Europe; Numerical Model; Emission; Eutrophication; Key region; Nitrogen Dioxide; Particulate Matter; PM; Source region; Surface Ozone; Tropospheric Ozone; Earth sciences; Geovetenskap; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : The main objectives of this thesis were to investigate the dependency of European air pollution on climate variability and emission source region. Calculations with a chemistry transport model (CTM) were conducted to investigate the influence of climate variability. READ MORE

  4. 17. Mesoscale processes in the polar atmosphere : radar remote sensing, balloon-borne in situ measurements and modelling

    Author : Maria Mihalikova; Suzanne Gray; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rymdteknik; Space Technology;

    Abstract : Mesoscale processes (atmospheric phenomena with horizontal scales ranging from a few tens to several hundred kilometres and lasting from a few tens of minutes to a few days) have the potential to influence the chemical composition of the troposphere. Tropopause folds and mountain waves are two important types of mesoscale processes. READ MORE

  5. 18. Airway antioxidant responses to oxidative air pollution and vitamin supplementation

    Author : Annelie Behndig; Anders Blomberg; Ian S Mudway; Ragnberth Helleday; Isabelle Romieu; Umeå universitet; []
    Keywords : Medicine; air pollution; ozone; diesel exhaust; airway inflammation; antioxidant; vitamin C; dehydroascorbate; vitamin supplementation; Medicin; lungmedicin; Lung Medicine;

    Abstract : Air pollutants, such as ozone (O3) and diesel exhaust particles, elicit oxidative stress in the lung. Antioxidants within the respiratory tract lining fluid (RTLF) protect the underlying tissue from oxidative injury. READ MORE

  6. 19. Stress-induced BVOC emissions from forests in Sweden

    Author : Erica Jaakkola; BECC: Biodiversity and Ecosystem services in a Changing Climate; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Volatile organic compounds; Plant stress; Forests; Volatile emissions; spruce bark beetle infestations; ozone stress; wildfire recovery; Picea abies Norway spruce ; Betula pubescens ssp. czerepanovii; Pinus sylvestris Scots pine ; sweden;

    Abstract : A changing climate is expected to lead to more extreme weather events, such as an increased frequency of droughts and forest fires. Changing forest conditions can offer benefits to species such as insects, including bark borers that thrive in warm conditions. READ MORE

  7. 20. Health effects of air pollution : innovative approaches for spatio-temporal evaluations

    Author : Massimo Stafoggia; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Air pollution is one of the major risk factors to human health, causing both short- and long-term effects and the global burden on mortality is estimated in more than 4 million deaths every year. Most of the evidence on the short-term effects is based on studies conducted in major cities, because data or estimates of air pollutants exposures in non-urban settings have been historically lacking.
