The Toxicity of Chromium in the Zero and Trivalent Formmple irritation of skin and the upper respiratory tract, induction of contact hypersensitivity, of genotoxicity as well as the property to induce lung tumor and nephrotoxicity are mainly due to hexavalent chromium compounds exposed at very few occupational sites. In contrast trivalent chromium and c

Analysis of Cobalt, Chromium and Nickel in Biological Materials - State of the Arth has led to the identification and elimination of many sources of error from sampling and sample treatment preceeding the analytical determination step. Results of these improvements are significantly lower normal (i.e. reference) levels for numerous elements as supposed before (Versieck and Cornel

Phenomenology of the Trace Element Burdening of the Human Organism by the In-Body Corrosion of Co-Crdistinguish two main classes according to their Co and Fe contents, respectively. One comprises the so-called stainless steels on an iron basis with differing amounts of Cr, Ni and Mo, mostly according to AISI 316L. This type of material only contains minor amounts (ca. 0.1%) of cobalt as impurity a

Stainless steels and titanium alloys are used for fabrication of internal fixation devices. Cobalt based alloys are not widely used in this application due to their high material an
