  2. 1. Measuring occupational dust exposure with a passive sampler

    Author : Mariam Shirdel; Ingvar Bergdahl; Britt Andersson; Håkan Wingfors; Christer Johansson; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; dust particles; mineral; PM10; PM2.5; respirable fraction; UNC passive aerosol sampler; working environment;

    Abstract : Objectives: In a working environment it is important to measure dust exposure to evaluate possible health issues. Passive sampling could be an alternative to active sampling with pumps when measuring occupational dust exposure. One passive sampler is the University of North Carolina passive aerosol sampler (UNC sampler). READ MORE

  4. 2. 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

  5. 3. Quartz in Swedish iron foundries : exposure and cancer risk

    Author : Lena Andersson; Håkan Westberg; Gunilla Lindström; Per Gustavsson; Örebro universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Case-control study; crystalline silica; exposure assessment; iron foundry; lung cancer; morbidity; occupational hygiene; respirable quartz; Enviromental Science; Miljövetenskap;

    Abstract : The aims of the studies underlying this thesis were to assess the exposure to quartz in Swedish iron foundries and to determine the cancer morbidity for Swedish foundry workers. A cohort of 3,045 foundry workers and a final measurement database of 2,333 number of samples was established. READ MORE

  6. 4. A novel technology for studying the disposition of drugs and toxicants in the lung : short inhalation exposures of the isolated and perfused rat lung to respirable dry particle aerosols

    Author : Pär Ewing; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Aerosol; inhalation; rat; lung; absorption; drugs; carcinogen; particles;

    Abstract : The disposition of solutes following the deposition of inhaled substances in the lung is a complex process that proceeds along parallel paths; passive diffusion of solutes through the air/blood barrier and local metabolism followed by blood-borne clearance to the circulation. Using the isolated and perfused lung (IPL) the pulmonary disposition of inhaled particles can be studied in great detail without interference from distal organs and systemic exposure. READ MORE

  7. 5. Occupational exposure to particles in relation to chronic obstructive pulmonary disease and cardiovascular disease

    Author : Karin Grahn; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Objective The working life is expanding with increased retirement ages as the population is aging, in Sweden but in also other parts of the world. However, workers with poor health might not cope with working in higher ages. READ MORE
