    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; stainless steel; iron; chromium; nickel; metal release; artificial rain; synthetic body fluid; Materialvetenskap; Materials science; Teknisk materialvetenskap;

    Sammanfattning : This study has been triggered by the fact that stainless steel is being increasingly used in new applications, where possible environmental effects may be a matter of concern. When stainless steel is exposed to a given environment, a key issue is the release of small amounts of the main alloying elements iron, chromium, nickel and molybdenum. LÄS MER

  3. 2. Bioaccessibility of Stainless Steels : Importance of Bulk and Surface Features

    Sammanfattning : With increasing environmental awareness, the desire to protect human beings and the environment from adverse effects induced by dispersed metals has become an issue of great concern and interest. New policies, such as REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) within the European Community, have been implemented to reduce hazards posed by the use of chemicals on producers and downstream users.
