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

   Författare :Katja Hagström; Kåre Eriksson; Gunilla Lindström; Paul Demers; Örebro universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Occupational hygiene; wood dust; resin acids; VOC; variability; determinant of exposure; overexposure; dermal exposure; Occupational medicine; 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.

3. 2. Setting occupational exposure limits : Practices and outcomes of toxicological risk assessment

   Författare :Linda Schenk; Christina Rudén; Alan Boobis; Michael Gilek; KTH; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Assessment Factor; DNEL; Euroepan Union; Occupational Exposure Limit; REACH; Risk Assessment; Regulatory Toxicology; SCOEL; Uncertainty Factor; Toxicology; Toxikologi;

   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

4. 3. Levels of brominated flame retardants in humans and their environment : occupational and home exposure

   Författare :Marie Karlsson; Bert van Bavel; Bo Strandberg; Örebro universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PBDE; BTBPE; DeBDethane; plasma; air; dust; Northern fulmar; egg; household; occupational exposure; Chemistry; Kemi; Kemi; Chemistry;

   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

5. 4. Biological and air monitoring of exposure to isocyanates

   Författare :Carl Johan Sennbro; Avdelningen för arbets- och miljömedicin; []
   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 : Exposure to isocyanates may induce disorders in the airways of workers. Therefore, application, development and validation of methods for exposure assessment is of great importance. LÄS MER

7. 5. Occupational exposure to fluorinated ski wax

   Författare :Helena Nilsson; Jonathan W. Martin; Örebro universitet; []
   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.
