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

    Author : Linda Schenk; Christina Rudén; Alan Boobis; Michael Gilek; KTH; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; 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;

    Abstract : 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. READ MORE

  2. 2. Contributions to Emission, Exposure and Risk Assessment of Nanomaterials

    Author : Rickard Arvidsson; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; nanoparticles; particle flow analysis; emission assessment; titanium dioxide; graphene; silver; risk assessment; exposure assessment; Nanomaterials; substance flow analysis.;

    Abstract : In recent years, synthetic nanomaterials have begun to be produced and used in increasingly larger volumes. These materials may cause new or increased risks to the environment, but no harmonized methods for structured assessment of their environmental risks exist. READ MORE

  3. 3. Isocyanates - assessment of human exposure

    Author : Håkan Tinnerberg; Avdelningen för arbets- och miljömedicin; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pollution control; Miljöteknik; kontroll av utsläpp; Analytical chemistry; Analytisk kemi; exposure; biomonitoring; occupational; isophorone diisocyanate; hexamethylene diisocyanate; methylenediphenyl diisocyanate; toluene diisocyanate; amines; aminoisocyanates; polyurethane; isocyanates; Liquid chromatography; Environmental technology; mass spectrometry;

    Abstract : Isocyanates are used mainly for manufacturing of polyurethane (PUR) foams, lacquers, elastomers and glues. The production of PUR exceeds 2 million tonnes per year and is increasing. Occupational exposure to isocyanates are associated with respiratory disorders. READ MORE

  4. 4. A step forward in using QSARs for regulatory hazard and exposure assessment of chemicals

    Author : Aleksandra Rybacka; Patrik Andersson; Christina Rudén; Anna Linusson; Uko Maran; Umeå universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; QSAR; in silico; non-testing tools; risk assessment; exposure assessment; hazard assessment; carcinogenicity; mutagenicity; reproductive toxicity; endocrine disruption; estrogen; androgen; transthyretin; sorption; Environmental Science; miljövetenskap; Computer Science; datalogi; Toxicology; toxikologi; Statistics; statistik;

    Abstract : According to the REACH regulation chemicals produced or imported to the European Union need to be assessed to manage the risk of potential hazard to human health and the environment. An increasing number of chemicals in commerce prompts the need for utilizing faster and cheaper alternative methods for this assessment, such as quantitative structure-activity or property relationships (QSARs or QSPRs).

  5. 5. Reproductive hazards in an industrial setting : an epidemiological assessment

    Author : Marianne Wulff; Umeå universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Occupational exposure; environmental exposure; copper smelter; epidemiology; adverse reproductive outcome;

    Abstract : Background: As more women of childbearing age engage in the workforceand a lot of new chemicals are available, a growing interest of diagnosing andpreventing reproductive disorders due to occupational and environmentalexposure has occurred. The source location of this thesis is the Rönnskärcopper smelter which is situated in the north of Sweden, in the municipality of Skellefteå. READ MORE
