  1. 6. Fine and Ultrafine Particles from Combustion Sources - Investigations with In-situ Techniques

    Författare :Joakim Pagels; Ergonomi och aerosolteknologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pollution control; Environmental technology; Teknik; Technological sciences; Indoor Air; In-Situ Measurement; Biomass Combustion; Morphology; Hygroscopic Growth; Volatility; TDMA; APS; ELPI; Respiratory Deposition; Fine Particles; Miljöteknik; kontroll av utsläpp; Ultrafine Particles;

    Sammanfattning : Fine airborne particles are associated with adverse health effects in the human population. The aim of this research was to develop and evaluate methods for in-situ characterisation of fine and ultrafine particles and to determine their deposition in the human airways. LÄS MER

    Sammanfattning : Over half of the world’s population live in urban areas, a trend which is expected to only grow as we move further into the future. With this increasing trend in urbanisation, challenges are presented in the form of the management of urban infrastructure systems. LÄS MER

  5. 9. Semipermeable membrane devices as integrative tools for monitoring nonpolar aromatic compounds in air

    Författare :Hanna Söderström; Mats Tysklind; Per-Anders Bergqvist; Jochen F. Muller; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Environmental chemistry; air pollution; alkyl-PAHs; atmosphere; bioavailability; boundary layer; diffusive sampling; emissions; integrative; membrane; monitoring; nitro-PAHs; PAHs; particles; passive samplers; PCBs; plants; PRCs; release rate; sampler design; sources; SPMDs; traffic; uptake rate; wind effect; wood burning; Miljökemi; Environmental chemistry; Miljökemi;

    Sammanfattning : Air pollutants pose a high risk for humans, and the environment, and this pollution is one of the major environmental problems facing modern society. Active air sampling is the technique that has been traditionally used to monitor nonpolar aromatic air pollutants. LÄS MER

  7. 10. Indoor environment and recurrent wheezing in young children

    Författare :Gunnel Emenius; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Child; asthma; allergy; wheezing; air pollution; NO2; indoor air quality; building construction; ventilation system; indoor humidity; house dust mites; damp buildings; moisture; moulds; prospective studies; child;

    Sammanfattning : Recurrent wheezing is one of the most common causes of morbidity and hospitalisation among infants and young children in many westernised countries. Respiratory infections and exposure to tobacco smoke have been identified as important risk factors. The indoor environment is also clearly of importance since we spend most of our time indoors.
