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

    Författare :Klas Persson; Georgia Destouni; Aldo Fiori; Stockholms universitet; []
    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.

    Sammanfattning : Essay I: This paper studies the effect of air pollution on infant health in Sweden. Combining register panel data on birth outcomes and family characteristics with pollution data, I estimate the effect of particulate matter (PM10) on several birth outcomes that previously have been shown to be predictive of future outcomes.

  4. 13. Source-Receptor Modeling of Air Pollution : Assessment of Source Contributions: Source Characterization and Chemometric Applications

    Författare :Emma Hedberg Larsson; Christer Johansson; H.-C. Hansson; Ralf Torgrip; Paulo Artaxo; Stockholms universitet; []
    Nyckelord :Particles; Source-receptor modeling; PMF; Elemental source profiles; Levoglucosan; Wood combustion; Air pollution; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : Particles released to the atmosphere from anthropogenic sources affect the Earth’s climate as well as the health of the population. Anthropogenic sources of atmospheric particles are e.g. the combustion of biomass and fossil fuels, road, brake and tire wear and various industrial activities. LÄS MER

  5. 14. Virtual Mobility and Pollution Prevention - The Emerging Role of ICT Based Communication in Organisations and its Impact on Travel

    Författare :Peter Arnfalk; Internationella miljöinstitutet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; pollution control; Environmental technology; travel reduction; pollution prevention; telework; web-meetings; audioconferencing; videoconferencing; virtual mobility; virtual communication; IT; IKT; ICT; Miljöteknik; kontroll av utsläpp; Informatics; systems theory; Informatik; systemteori; Telecommunication engineering; Telekommunikationsteknik;

    Sammanfattning : Information and Communication Technologies change the way we work and communicate, enabling us to telework and to have virtual meetings - collaborating without a physical meeting. This can influence the need for commuting and business travel by provision of access to an activity without mobility - virtual mobility. LÄS MER

  7. 15. Patronage, Politics and Pollution : precarious NGO-state relationships : urban environmental issues in south India

    Författare :Håkan Tropp; Linköpings universitet; []
