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

    Detta är en avhandling från Umeå : Umeå University

    Författare :Aleksandra Rybacka; Patrik Andersson; Christina Rudén; Anna Linusson; Uko Maran; [2016]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; 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;

    Sammanfattning : 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).

    Sammanfattning : Chemicals are present in or have been used for production of a large number of products available for private consumers. There are many benefits and useful applications of chemicals, but risks and negative side-effects shall not be overlooked. LÄS MER

  3. 3. Uncertainty in risk assessment contents and modes of communication

    Detta är en avhandling från Stockholm : KTH

    Författare :Rikard Levin; Sven Ove Hansson; Erik Olsson; [2005]
    Nyckelord :HUMANIORA; HUMANITIES; uncertainty; scientific uncertainty; characterization of uncertainty; decision-making under uncertainty; risk assessment; risk management; HUMANITIES and RELIGION History and philosophy subjects Philosophy subjects; HUMANIORA och RELIGIONSVETENSKAP Historisk-filosofiska ämnen Filosofiämnen;

    Sammanfattning : Assessments of chemical health risks are performed by scientific experts. Their intended use is as bases for decisions. This thesis tries to answer the questions of how uncertainty is, and should be, communicated in such risk assessments. The thesis consists of two articles and an introductory essay. LÄS MER

    Sammanfattning : Do metal particles (including particles of pure metals, alloys, metal oxides and compounds) pose a hazard or risk to human health? In the light of this question, this thesis summarizes results from research conducted on metal particles, and describes the elaboration and implementation of an in vitro test methodology to study metal release from particles through corrosion and dissolution processes in synthetic biological media relevant for human exposure through inhalation/ingestion and dermal contact.Bioaccessible metals are defined as the pool of released metals from particles that potentially could be made available for absorption by humans or other organisms.
