  1. 11. Be Aware of the Indoor Air. Physicochemical Characterization of Airborne Fine Particles in Occupied Homes : Physicochemical Characterization of Airborne Fine Particles in Occupied Homes

    Författare :Yuliya Omelekhina; Metalund; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Ultrafine particles UFP ; PM2.5; Black carbon; Indoor sources; Occupied homes; energy renovation;

    Sammanfattning : Negative health effects of exposure to particles of outdoor origin have been confirmed by epidemiological studies. In developed countries, we spend on average 65% of our time in our homes. Thus, the properties of airborne particles indoors need to be understood. LÄS MER

  3. 12. Health-related aerosol particle studies, respiratory tract deposition and indoor source identification

    Författare :Jakob Löndahl; Kärnfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; aerosol particle; health; ultrafine particles; nanoparticle; deposition; respiratory tract; Fysicumarkivet A:000;

    Sammanfattning : Aerosol particles have, since Classical Antiquity, been linked to adverse effects on human health. It is estimated that the particles in urban air pollution causes 100 000 deaths in Europe each year, whereof 5 000 in Sweden. LÄS MER

  4. 13. Aerosol characterization in real life and a methodology for human exposure studies in controlled chamber settings

    Författare :Christina Isaxon; NanoLund: Centre for Nanoscience; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aerosol; human exposure study; exposure; emission; ultrafine particles; aerosol generation; aerosol characterization; candle; terpene; welding; CNT; indoor;

    Sammanfattning : Airborne particles are everywhere around us, and have always been. Particles generated by human activities has increased drastically since industrialization, and several epidemiological studies have shown that inhaled particles can cause adverse health effects. LÄS MER

  5. 14. Environmental Factors in Relation to Asthma and Respiratory Symptoms among Schoolchildren in Sweden and Korea

    Författare :Jeong-Lim Kim; Gunilla Wieslander; Dan Norbäck; Lena Elfman; Nils Åberg; Uppsala universitet; []
    Nyckelord :Medical sciences; Allergen; allergy; asthma; dampness; diet; environment; formaldehyde; nitrogen dioxide; plasticizer; schoolchildren; ultrafine particles; MEDICIN OCH VÅRD;

    Sammanfattning : This thesis studied environmental factors in relation to asthma and respiratory symptoms among schoolchildren in two countries. In Sweden, 1014 pupils (5-14 year) in 8 schools participated. Wheeze was reported by 7.8%, current asthma by 5. LÄS MER

  7. 15. Charting the human lung with inhaled nanoparticles : Development of AiDA - a new diagnostic technique for respiratory disease

    Författare :Jonas Jakobsson; NanoLund: Centre for Nanoscience; []
    Nyckelord :Aerosol; lung; lung deposition; respiratory tract; nanoparticles; ultrafine particles; airspace dimension assessment; AiDA; Chronic obstructive pulmonary disease; COPD; lung morphology;

    Sammanfattning : Changes to the smallest structures of the distal lung are often the first sign of severe respiratory disease, but to date methods to detect and quantify these changes are limited. Chronic obstructive pulmonary disease (COPD) is currently estimated to be the third most common cause of death worldwide, but is to a large extent under-diagnosed, especially at early stages. LÄS MER
