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 ...

Excessive chromium intake in children receiving total parenteral nutrition
The Lancet, 1992Various expert bodies have recommended that the daily parental intake of chromium in children receiving total parenteral nutrition (TPN) should be 0.20 micrograms/kg. To test whether this recommendation is appropriate, we assessed chromium intake, serum chromium concentrations, and renal function in 15 children receiving TPN. The median duration of TPN

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.

Bulletin of the Academy of Sciences, USSR Division of Chemical Science, 1966
1. A rapid, simple, and accurate micromethod for determining chromium (VI) and total chromium in aluminum-chromium catalysts has been developed. 2. The oxides of potassium and the rare-earth elements do not interfere with the determination of chromium.

Mikrochimica Acta, 1982
A spectrophotometric method has been developed for the determination of chromium in waste water with 5-Br-PADAP (2-(5-brorno-2-pyridylazo)-5-diethylaminophenol). Chromium(III) forms a blue-purple complex at pH 4.7 upon heating. The color is very stable and is highly sensitive for chromium.

Journal of Parenteral and Enteral Nutrition, 1986
A 6‐yr, 4‐month‐old boy was started on total parenteral nutrition (TPN) because of chronic diarrhea. The TPN regimen (3 liter/day) initially included supplemented Cr (3 μg/day) in addition to standard components (including FreAmine III). At age 8 yr, 8 months, the serum Cr level was elevated: 3.7 ng/ml (normal 0.03–0.85).
