  2. 21. 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

  4. 22. Engineered nanomaterials in in vivo and in vitro models

    Author : Laura Abariute; NanoLund: Centre for Nanoscience; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; III-V semiconductor nanowires; Nanoparticle exposure; Mouse exposure; Cell exposure; Nanotoxicology; Nanosafety; Fysicumarkivet A:2018:Abariute;

    Abstract : Nanotechnology and engineered nanomaterials (ENM) empower existing technologies. One of the great examples are III-V semiconductor nanowires (NW), which have a broad application range. The occupational safety and hazard organizations draw attention to ENM, as their physical and chemical characteristics differ from the ones of bulk materials. READ MORE

  5. 23. Exposure to crime as a consequence of poverty : five investigations about relative deprivation, poverty and exposure to crime

    Author : Daniel Larsson; Björn Halleröd; Henrik Tham; Umeå universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; poverty; exposure to crime; fear of crime; welfare problems; Sweden; Britain; Sociology; Sociologi;

    Abstract : This thesis contains five studies that in different ways investigate poverty and the relation between poverty and exposure to crime. The basis of the thesis has been the question of how poverty is related to other welfare problems such as unemployment and health problems, focusing on exposure to crime and fear of crime. READ MORE

  6. 24. Occupational exposure during production of wood pellets in Sweden

    Author : Katja Hagström; Kåre Eriksson; Gunilla Lindström; Paul Demers; Örebro universitet; []
    Keywords : 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;

    Abstract : 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.
