  1. 1. Setting occupational exposure limits Practices and outcomes of toxicological risk assessment

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Linda Schenk; KTH.; Södertörns högskola.; [2011]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURAL SCIENCES Chemistry Biochemistry Toxicology; NATURVETENSKAP Kemi Biokemi Toxikologi; Assessment Factor; DNEL; Euroepan Union; Occupational Exposure Limit; REACH; Risk Assessment; Regulatory Toxicology; SCOEL; Uncertainty Factor;

    Sammanfattning : Occupational Exposure Limits (OELs) are used as an important regulatory instrument to protect workers’ health from adverse effects of chemical exposures. The main objective of this thesis is to study risk assessment practices in the setting of OEL in order to produce knowledge that will help improve the consistency and transparency of OELs. LÄS MER

    Sammanfattning : Plasma from workers at an electronic dismantling plant were analysed for tri- to heptaBDEs (brominated diphenyl ethers), during 18 months. The different exposed groups showed concentrations ranging from 0.06to 2.8 ng g-1 (l. LÄS MER

  3. 3. Biological and air monitoring of exposure to isocyanates

    Detta är en avhandling från Department of Occupational and Environmental Medicine, Lund University

    Författare :Carl Johan Sennbro; Lunds universitet.; Lund University.; [2005]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; industrial medicine; Occupational health; asthma; protein adducts; polyurethane; biomarkers; occupational exposure; DBA; ICA; NDI; MDI; TDI; Diisocyanates; Isocyanates; Biomonitoring; Air monitoring; arbetsmiljömedicin; Yrkesmedicin;

    Sammanfattning : Popular Abstract in Swedish På de allra flesta arbetsplatser utsätts arbetstagarna för risker, och de kemiska hälsoriskerna utgör en omfattande del av dessa. Till exempel är det många som får astma orsakad av exponeringar i arbetsmiljön. En vanlig orsak till yrkesrelaterade luftvägsbesvär är exponering för isocyanater. LÄS MER

  4. 4. Occupational exposure during production of wood pellets in Sweden

    Detta är en avhandling från Örebro : Örebro universitet

    Författare :Katja Hagström; Örebro universitet.; [2008]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Occupational hygiene; wood dust; resin acids; VOC; variability; determinant of exposure; overexposure; dermal exposure; MEDICINE Social medicine Public health medicine research areas Occupational medicine; MEDICIN Socialmedicin Folkhälsomedicinska forskningsområden Yrkesmedicin; Enviromental Science; Miljövetenskap;

    Sammanfattning : The aims of the studies underlying this thesis were to assess workers’ air exposure to wood dust and various chemicals, and to evaluate the variability in exposure and occupational dermal exposure to resin acids during the production of wood pellets in Sweden. Personal air measurements of wood dust, monoterpenes, resin acids and nitrogen dioxide (as a marker of diesel exhaust), accompanied by area measurements of these substances, VOCs and carbon monoxide, were performed at up to ten plants.

  5. 5. Occupational exposure to fluorinated ski wax

    Detta är en avhandling från Örebro : Örebro universitet

    Författare :Helena Nilsson; Örebro universitet.; [2012]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Perfluorinated; polyfluorinated; FIS; occupational exposure; ski wax; biotransformation; metabolism; fluorotelomer alcohol; fluorotelomer acid; aerosol; dust; UPLC MS-MS; GC MS-MS; Kemi; Chemistry;

    Sammanfattning : Per- and polyfluorinated substances (PFAS) are used in the production of ski wax to reduce the friction between the snow and the ski. In this occupational study of ski wax technicians’ exposure to PFAS and particulate aerosol we have collected whole blood (wb) (n =94), air (n =84) and aerosol (n =159) samples at World Cup events from 2007-2011.
