OBJECTIVE A systematic review of the effect of chromium supplementation on glucose metabolism and lipid levels. RESEARCH DESIGN AND METHODS A literature search was conducted in MEDLINE and the Commonwealth Agricultural Bureau. Eligible studies were English language randomized controlled trials of chromium supplement intake > or = 3 weeks, with > or = 10 participants receiving chromium. All tr...

The distribution and mobility of chromium in the soils and sludge surrounding a tannery waste dumping area was investigated to evaluate its vertical and lateral movement of operational speciation which was determined in six steps to fractionate the material in the soil and sludge into (i) water soluble, (ii) exchangeable, (iii) carbonate bound, (iv) reducible, (v) oxidizable, and (vi) residual ...

The raw materials traditionally used as sources of chromium carriers (ferrochromium, chromium oxide and chromium powder) in application chromizing processes present a high price and some difficulties for ferrochromium grinding. In this work there is an assessment of the effect that has the use of the products of a reduction aluminothermic chromium concentrate on the characteristics and properti...

Human periodontal ligament fibroblasts and L 929 cell line labelled with chromium 51 were examined by electron microscope to evaluate the effect of the chromium labeling on the cell ultrastructure. The cells were labeled with chromium 12-20 hours before the start of the experiment. Af ter two and four hours of incubation at 37°C and 100% humidity, the cells were examined by scanning and transmi...

Ten years have elapsed since the International Agency for Research on Cancer (IARC) evaluated the carcinogenicity of chromium and chromium compounds. Further studies performed during the last decade have provided further epidemiological, experimental and mechanistic data which support the IARC conclusions. A wealth of results indicate that, at variance with chromium(0) and chromium(III), chromi...

Despite the high competition of synthetic fibers leather is nowadays still widely used for many applications. In order to ensure a sufficient stability of the skin matrix against many factors, such as microbial degradation, heat and sweat, a tanning process is indispensable. Using chromium (III) for this purpose offers a multitude of advantages, thus this way of tanning is widely applied. Durin...

the isolated fungi species of different kinds from chromium contaminated soil sites located in nagalkeni, chennai were used for reducing chromium(vi) in a tannery industry wastewater of nagalkeni, chennai.  the experiments were conducted to know biosorption potential of isolated fungi species for removing chromium(vi) in a tannery industry wastewater against the different ph, fungi biomass and ...

the effect of compost and humic acid in mobility and concentration of cadmium and chromium in contaminated soil were investigated. experiment was carried out with three levels of soil cadmium and chromium and two organic matters (compost and humic acid). the study was performed in a randomized complete block design with 3 replicates. results indicated that application of organic substances enha...

In the ongoing investigation into the biological importance and toxicity issues surrounding the bioinorganic chemistry of chromium, the accepted literature procedure for the isolation of the biological form of chromium, low molecular weight chromium binding protein (LMWCr) or chromodulin, was investigated for its specificity. When chromium(VI) is added to bovine liver homogenate, results presen...

Industrial wastewater contain higher quantities of salts besides chromium (VI) ions, therefore, the effect of these salts on the adsorption of chromium (VI) should be studied. In this research, the batch removal of toxic hexavalent chromium ions from wastewater and aqueous solution using two different activated carbon marine algae Gracilaria (red algae) and Sargassum sp. (brown algae) were exam...
