In contrast to the prostheses alloy dissemination of cobalt and chrome, the concentration of chrome was higher than that of cobalt in the capsular tissue (Tager 1976).
Another reason for the relatively high concentration of chrome might be the corrosion in the surrounding of carbides (Ungethum et al. 1984) followed by loss of chrome, which deposits in the capsular tissue.
A reason for the relatively high concentration of chrome in the capsular tissue may be found in the relatively long half-life (of disappearance from soft tissue) of chrome, which is 600 days, in contrast to the half-life of cobalt, which is only 9 days.
Concentrations of chrome (a), lead (b), nickel (c), zinc (d), cadmium (e), and copper (f) that are relevant for legal waste and fertilizer requirements as a function of volatile solids.
Concentrations of nickel and chrome in fine particulate matter have been found to be particularly high in comparison with levels measured in other Flemish locations.
The concentration of the heavy metals of chrome, lead, nickel, cadmium, and zinc in the biomass falls with increasing VS fraction (Fig. 6a e).
For removing chrome, an acid solution of about 30-40% concentration should suffice.
For example, concentrations of heavy metals (e.g., chrome, mercury, lead, cadmium) introduced primarily from anthropogenic activities in the Rhine River basin are higher during drought years (Zwolsman and van Bokhoven 2007).
The aim of the study was to measure metal ion concentration (titanium - Ti, cobalt - Co, chrome - Cr, molybdenum - Mo, nickel - Ni, aluminium - Al) around loosened femoral stems and compare their levels around uncemented and cemented implants.
In high concentrations, it can be used to remove chrome plating from metal objects.
EDX microanalysis exhibited the elements of mars yellow and mars red pigments, and ICP OES method showed the concentration of chromium element that is characteristic for chrome oxide green pigment.
