It is used in the preparation of chrome catalysts, in textile printing operations, and as a corrosion inhibitor. Further, the use of leaves collected from chromium polluted habitat in medicinal preparation is not safe for human health due to high chromium contents. Chromium nitrate is used in the manufacture of alkali metal-free catalysts and in preservation. The study concludes that plant could grow under chromium stress and protect themselves from phytotoxicity of Cr by altering various metabolic processes. Further, chromium treated plants yielded more eugenol (a major component of Ocimum essential oil) in comparison to the control (14.46, 24.61, 16.80, 3.83% more eugenol from 10, 20, 50 and 100 μM chromium exposed plants, respectively). This reflects the sensitivity of the enzyme to the chromium. Therefore, reduced ascorbate peroxidase activity in chromium treated O. However, APX took a little part in detoxification of H 2O 2 due to its sensitivity to chromium. Hyperactivity of the superoxide dismutase (SOD), guaiacol peroxidase (GPX) and catalase indicated that antioxidant enzymes played an important role in protecting the plant from chromium toxicity.
tenuiflorum leaves showed increased proline content. In addition, chromium toxicity resulted in the reduction of nitrate reductase activity through impaired substrate utilization. It is used in the preparation of Chrome catalysts, in textile printing operations, and as a corrosion inhibitor. tenuiflorum were reflected by the reductions in photosynthetic pigments, protein, cysteine, ascorbic acid and non-protein thiol contents. Chromium induced lipid peroxidation coupled with potassium leakage. Uses : chromium (III) nitrate solution is an intermediate chemical used in the manufacture of other organic and inorganic chromium compounds. exposed to various concentrations of chromium (0.0, 10.0, 20.0, 50.0, 100.0 μM) accumulated high amount of chromium in various plant parts in a concentration and duration dependent manner.
