  2. 1. Quantification of sources and removal mechanisms of atmospheric aerosol particles

    Author : Henrik Grythe; Johan Ström; Dominick Spracklen; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; aerosol; aerosol removal; aerosol emission; aerosol sources; FLEXPART; Arctic aerosol; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : The focus of this work has been to quantify important processes for climatically relevant aerosols, and to improve our understanding of, and ability to accurately model, aerosols in the atmosphere on a large scale. This thesis contains five papers focused on different parts of the life cycle of atmospheric aerosol particles. READ MORE

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

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

    Abstract : 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. READ MORE

  6. 4. Isocyanates - methodology for gas and particle generation, sampling and detection

    Author : Daniel Gylestam; Marianne Dalene; Gunnar Skarping; Daniel Karlsson; Dhimiter Bello; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Isocyanate; PUR; Dry sampler; PTR-MS; Transfer line; PPE; Environmental Chamber; Respirable Particles; Denuder Impactor; Aerosol; Particles; Impinger; air sampling; LC-MS; di-n-butylamine; DBA; ICA; MIC; HDI; TDI; IPDI; MDI; Occupational Exposure; Exposure; Occupational Health; Analytical Chemistry; analytisk kemi;

    Abstract : Isocyanates are mainly used in the industry for the production of polyurethane (PUR) plastics. Workers are at risk of being exposed during the manufacturing of PUR. During thermal degradation of PUR, isocyanates are released and workers involved in hot work such as fire-fighting, welding etc. may also be exposed. READ MORE

  7. 5. Development and Evaluation of Methods in Source Apportionment of the Carbonaceous Aerosol

    Author : Johan Martinsson; Kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; carbonaceous aerosol; organic aerosol; aerosol particles; source apportionment; air pollution;

    Abstract : Carbonaceous aerosols are known to affect human health negatively and to affect the climate of Earth. As specific types of aerosols originate from specific sources, it is important to know the amount of aerosols emitted from each source. Aerosol source apportionment is an important tool in mitigating air pollution and improving air quality. READ MORE
