  1. 1. Quantifying pollutant spreading and the risk of water pollution in hydrological catchments A solute travel time-based scenario approach

    Detta är en avhandling från Stockholm : Department of Physical Geography and Quaternary Geology, Stockholm University

    Författare :Klas Persson; Stockholms universitet.; [2011]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; water pollution; catchment; pollution risk; scenario analysis; uncertainty; Physical Geography; naturgeografi;

    Sammanfattning : The research presented in the thesis develops an approach for the estimation and mapping of pollutant spreading in catchments and the associated uncertainty and risk of pollution. The first step in the approach is the quantification and mapping of statistical and geographical distributions of advective solute travel times from pollutant input locations to downstream recipients.

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

    Detta är en avhandling från Stockholm : Department of Applied Environmental Science (ITM), Stockholm University

    Författare :Camilla Andersson; Stockholms universitet.; [2009]
    Nyckelord :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; NATURAL SCIENCES Earth sciences; NATURVETENSKAP Geovetenskap; tillämpad miljövetenskap; Applied Environmental Science;

    Sammanfattning : 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. LÄS MER

  3. 3. Short-term and Long-term Exposure to Air pollution and Stroke risk

    Detta är en avhandling från Occupational and Environmental Medicine

    Författare :Anna Oudin; [2009]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Long-term effects; Two-phase methods; Hemorrhagic stroke; Ischemic stroke; Short-term effects; Hospital admissions; Air Pollution;

    Sammanfattning : Background: Stroke is a major cause of mortality and morbidity across the world. Air pollution has become an acknowledged risk factor for stroke, especially for acute effects. There is less support for effects by chronic exposure due to the methodological challenges inherent in such studies. LÄS MER

  4. 4. Accident risk and safety protection in automated production

    Detta är en avhandling från National Institute for Working Life

    Författare :Tomas Backström; [1996]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Environmental technology; computer control; Safety; mechanization; safeguard; safety device; model; manufacturing; industry; technical fault; machine failure; prevention; Teknik; Technological sciences; pollution control; Miljöteknik; kontroll av utsläpp; Management of enterprises; Företagsledning; management;

    Sammanfattning : This thesis treats automation accidents in manufacturing industry. An automation accident is defined as an accident whereby a person is injured by an energy which was controlled, or should have been controlled, by an automated item of equipment. The thesis comprises five papers. LÄS MER

  5. 5. Prescription – Pollution – Poo – Pandemics - Priorities Neuraminidase Inhibitors from an Environmental Resistance Development Perspective

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Marie Nykvist; Uppsala universitet.; [2018]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Influenza A virus; neuraminidase inhibitor; resistance; environmental; Mallard; zanamivir; avian influenza;

    Sammanfattning : The natural Influenza A virus (IAV) host is waterfowl. Human IAV is treated with neuraminidase inhibitors (NAIs), which are stockpiled worldwide in case of an IAV pandemic. As the drugs escape regular waste water treatment, they can be detected in river waters. LÄS MER
