Chromium-VI would impose detrimental effects morphological, physiological, and metabolic in plants. This study aimed to research the impact of citric acid (0, 2.5 and 5 mM), on different the morphological and physiological characteristics of garden cress exposed to chromium-VI stress (0, 1, and 10 mM). Results showed that some growth parameters, chlorophyll, carotenoids, and DPPH activity decre...

a general overview on the prospective of various oxidation and combined processes in the treatment of tannery industry effluent are reported. various oxidation and combined processes such as uv/h2o2/hypochlorites, fenton and electro-oxidation, photo-chemical, photo-catalytic, electro-catalytic oxidation, wet air oxidation, ozonation, biological followed by ozone/uv/ h2o2, coagulation or ele...

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...
