    Sammanfattning : Metallic nanoparticles possess unique properties due to their size and are widely used in e.g. consumer products. From this follows a need to identify and assess potential risks of human and environmental exposure. LÄS MER

  3. 2. Bioaccessibility, corrosion and surface properties of metals, alloys and metallic powder in biological fluids of relevance for occupational and consumer health hazard assessment

    Författare :Xuying Wang; Inger Odnevall Wallinder; Yolanda S. Hedberg; Lars Nyborg; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Metal and alloy; metal release; synthetic biological fluids; surface oxide; corrosion resistance; hazard assessment; Kemi; Chemistry;

    Sammanfattning : When assessing hazards of metals, alloys, and metal-containing items, the metal release (bioaccessibility) is of high importance. Triggered by increasingly stricter hazard classifications for metals, especially cobalt (Co), and limited knowledge, the aim of this doctoral thesis is to assess correlations between the metal/alloy surface characteristics, corrosion and metal release pattern in different simulated biological fluids relevant to human exposure scenarios (dermal, ingestion and inhalation, Papers I-V).
