[Detection of metals in human tissues by spectrum analysis]
Abstract:
Potentialities of spectrography experts were demonstrated to be helpful to the employees of patient-care facilities (expertise and research institutions) in solving a variety of burning issues by joint effort. Tissue samplings, hairs and daily urine were comparatively analyzed, by the example of using the low-friction hip arthroplasty by comochrome friction Protasu-21WF, for the content of microelements (ME) belonging to the hip endoprosthesis. We found that MEs (Co, Cr, Mo) are mostly discharged during the first year of endoprosthesis utilization, after which, a regular reduction of concentrations was noted. No exceeding norms were registered in any cases, which denotes a minimal wear of the friction pair.

Effects of EDTA on End-Point Detection Methods
In the visual method, metal-ion indicators (metallochromic dyes), which have distinct colors in their free and complex forms, are added to the mixture to signal the titration's end point. They form stable complexes with metal ions, but these complexes are weaker than the corresponding metal–EDTA complexes. As a result, EDTA...
