Isotope dilution measurement of inorganic chromium(III) and total chromium in seawater
Marine Chemistry, 1984Abstract A reproducible, low-blank, isotope-dilution technique for the determination of inorganic Cr(III) and total dissolved chromium in seawater has been developed. Analysis of coastal water from Brittany, France, confirms that inorganic Cr(III) exists in excess of the thermodynamic equilibrium value calculated from the model of Elderfield (1970 ...

Chromium deficiency after long-term total parenteral nutrition
Digestive Diseases and Sciences, 1986A 63-year-old female developed unexplained hyperglycemia and glycosuria during administration of a total parenteral nutrition regimen on which she had been stable for several months. Because the patient had no history of diabetes or evidence of an infection, chromium deficiency was considered.

Dermatitis Associated With Chromium Following Total Knee Arthroplasty
The Journal of Arthroplasty, 2011All metal implants release metal ions because of corrosion. Although 20% to 25% of patients develop metal sensitivity after total joint arthroplasty, which is 10% higher than that in the general population, only very few highly susceptible patients exhibit symptoms.

Journal of Electroanalytical Chemistry, 2017
Abstract We report a sensitive electrochemical protocol based on an easy-to-produce and disposable plastic electrode for the determination of total chromium (Cr) and Cr(VI). The electrode was fabricated by sputtering a thin layer of gold on a polyethylene terephthalate (PET) substrate.

Increased Blood Cobalt and Chromium After Total Hip Replacement
Journal of Toxicology: Clinical Toxicology, 1999To determine metal concentrations in blood and urine of patients who received cobalt-chromium-alloy metal on metal hip implants.Cobalt and chromium were determined in blood and urine of 76 patients and 26 controls by electrothermal atomic absorption spectroscopy.A significant postoperative elevation of the metal concentrations was observed for total ...

Determination of total chromium in sediments by FAAS
Fresenius' Journal of Analytical Chemistry, 1995The determination of chromium by flame atomic absorption spectroscopy (FAAS), e.g. as performed for environmental matrices, is still a controversial matter as can be concluded from a literature review. Most controversy is due to the measurement conditions or the effect of the interferences; other conditions such as digestion seem to be less critical ...

Total chromium and nickel contents of Scottish soils
Geoderma, 1986Abstract The frequency distributions of chromium and nickel contents in Scottish soils are reported and the relation of the concentrations of these elements to some other soil variables is examined. The frequency distributions of both elements are approximately log-normal and are described in terms of the derived mean ( x ∗ ) and the ...

Determination of total chromium in phosphate rocks by ion chromatography
Journal of Chromatography A, 1999Chromium(VI) is one of seven elements which is classified in the fertilizer industry as being harmful to plants and biological systems. Phosphate rocks represent the raw material for complex fertilizer production in the world. This paper investigates for the first time the determination of total chromium in phosphate rocks by ion chromatography.
