  2. 1. Passive sampling of PAHs and some trace organic compounds in occupational and residential air: needs, evaluation and limits

    Author : Pernilla Bohlin; Göteborgs universitet; []
    Keywords : passive air sampling; PAH; POP; occupational environment; residential environment; exposure; stationary air sampling; personal air sampling; PUF; evaluation;

    Abstract : Human exposure to elevated levels of polycyclic aromatic hydrocarbons (PAHs) and trace organic compounds (e.g. PCB, OCP, PBDE) can be related to negative health effects. This raises demands of exposure measurements to be performed. READ MORE

  4. 2. Cabin Air Quality in Commercial Aircraft : Exposure, Symptoms and Signs

    Author : Torsten Lindgren; Dan Norbäck; Gunilla Wieslander; Jan Sundell; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine; airline crew; aviation medicine; micro-organism; cabin air quality; air humidity; atopy; occupational exposure; environmental tobacco smoke ETS ; psychosocial work environment; Medicin; Dermatology and venerology; clinical genetics; internal medicine; Dermatologi och venerologi; klinisk genetik; invärtesmedicin; arbets- och miljömedicin; Occupational and Environmental Medicine;

    Abstract : The objective of the dissertation was to study the cabin environment, and identify personal and environmental risk factors, associated with symptoms, and perception of cabin air quality. Another objective was to study if ban of smoking, and increased relative air humidity on intercontinental flights, could have a beneficial health effect. READ MORE

  5. 3. Ultrafine Particles in the Indoor Environment: Field and Laboratory Measurements

    Author : Uve Matson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; airborne particles; aerosols; indoor air; outdoor air; air quality;

    Abstract : Clean air is one of the most fundamental human needs since poor air quality affects the health and the environment. It has been shown that people spend on average over 85 % of their time at work, home, school etc. Therefore, human exposure to air pollution may occur mostly indoors. Despite this fact, outdoor air pollution is also important. READ MORE

  6. 4. The indoor environment in schools : Respiratory effects and air quality

    Author : Greta Smedje; Uppsala universitet; []
    Keywords : Medical sciences; Allergy; asthma; cat allergen; cleaning; dust; formaldehyde; furniture; mould; schoolchildren; ventilation; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; arbets- och miljömedicin; Occupational and Environmental Medicine;

    Abstract : The main objective of this work was to investigate relationships between the schoolenvironment and asthma and asthmatic symptoms in schoolchildren. Data on symptoms werecollected through postal questionnaires answered by 1,732 pupils in 39 randomly selectedschools, and were related to data on exposures obtained through hygienic measurements in theschools.

  7. 5. Norovirus Tracing in Environmental and Outbreak Settings - Experiences of waterborne, foodborne and nosocomial transmission

    Author : Nancy P Nenonen; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Norovirus; tracing; environment; foodborne; outbreak; waterborne; nosocomial; mussels; GI.1; oysters; GII.4; dust; surfaces; air; molecular epidemiology;

    Abstract : Noroviruses (NoV), a major cause of acute gastroenteritis in hospital settings, also occur as sporadic infections or periodic non-seasonal community outbreaks. Human NoV replicates to high concentration in the intestinal tract, is readily transmitted by the faecal-oral route, hand-to-hand contact, contaminated food and water, and by aerosols. READ MORE
