Determining low levels of chromium in biological samples by ICP-MS using hydrogen as reaction gas
Chromium is a key ingredient in a number of metal alloys used for metal implants which, despite being coated with inert surface layer coatings, can break down over time as a result of biocorrosion. Leeching of metal ions from implants into surrounding bone, tissue, and body fluids can cause severe health problems. Although the toxicity of the metal is low, there is a potential health risk if ...
