Chromium in Agricultural Soils and Crops: A Review ...
Apr 22, 2017 · Chromium is the 7th most abundant element in the Earth and the 21st on the Earth's crust (– mg kg −1) (Katz and Salem 1994).The most stable forms of this metal in the environment and in biological systems are the trivalent Cr(III) and hexavalent Cr(VI) (Becquer et al. 2003).Other intermediate valence states of Cr exist in nature, but they are generally unstable....

The Donskoy ore mining and processing plant, Aktobe ferroalloys plant, the Aksu ferroalloys plant and the Kazmarganets mining enterprise are the four mining sites to contribute the majority of the chromium ore. 4. India. India's chromium production came in million tonnes in 2019....
Chromium Recycling
Mar 24, 2018 · In 1989, materials containing 1,208 mt of chromium were consumed for these alloys. Feed to processing also included prompt scrap containing 556 mt of chromium and home scrap containing 306 mt of chromium. During processing, material containing 259 mt of chromium reported to processing losses....
Induction of micronuclei and nuclear abnormalities in ...
Sep 10, 2005 · Chromium processing plant effluent water typically contains trivalent chromium (Cr(III)) produced by reduction of hexavalent chromium (Cr(VI)) during the chemical processing in the waste treatment unit. Cr(VI) is an environmentally and occupationally significant mutagen and carcinogen....

The alkali used for precipitating chromium ultimately contributes additionally to the total dissolved solids (TDS) content in effluent (Ramasami, 1996). The reuse of supernatant solution from chromium recovery plants in various pretanning operations is one of the inplant control approaches to contain TDS (Langerwerf, 1999)....
(PDF) Chromium toxicity in plants | Arun Shanker ...
Chromium uptake, transloion and accumulation plants could be because Cr is immobilized in the vacuoles of the root cells, thus rendering it less toxic, which may be a The first interaction Cr has with a plant is during its natural toxicity response of the plant (Shanker et al., 2004a). uptake process....

Adsorption Characteristics and Transport Behavior of Cr(VI ...
This study explored the stratigraphic distribution and soil/shallow aquifer characteristics surrounding a chromium ore processing residue (COPR) dumpsite at a former chemical factory in China. Total Cr levels in top soils (5–10 cm) nearby the COPR dumpsite were in the range of – mg/kg. Shallow aquifers (1#x2013;6#x2009;m) nearby the COPR dumpsite showed a maximum total Cr ......
Extraction of Chromium from Chromite Ore
Jul 20, 2017 · Chromium has a wide variety of appliions in the modern world. Its major uses are in stainless steels and the plating of metals. Other important uses include alloy steel, heating elements, pigments, leather processing, alysts, and refractories....
Chromium (Cr) and water
Chromium (VI) compounds are toxic at low concentrations for both plants and animals. The mechanism of toxicity is pH dependent. These compounds are more mobile in soils than chromium (III) compounds, but are usually reduced to chromium (III) compounds within a short period of time, reducing mobility....
Chromium (Cr)
Plants usually absorb only chromium(III). This may be the essential kind of chromium, but when concentrations exceed a certain value, negative effects can still occur. Chromium is not known to accumulate in the bodies of fish, but high concentrations of chromium, due to the disposal of metal products in surface waters, can damage the gills of ......
