Chromium accumulation in submerged aquatic plants treated with tannery effluent at Kanpur, India.
Aquatic macrophytes have been widely studied because of their capability of absorbing contaminants from water and their subsequent use in biomonitoring. This study presents a comparison of Cr accumulating potential of submerged aquatic plants viz Vallisneria spiralis and Hydrilla verticillata. These plants were treated with various concentrations of treated tannery effluent collected from UASB,...
متن کاملHair chromium concentration and chromium excretion in tannery workers.
Hair and urine samples were collected from 34 male tannery workers and from 12 normal adults. Eighteen of the workers dealt directly with chromium and the remaining 16 (controls) worked in the offices and kitchen of the same factory. All were found to be clinically healthy. Chromium was determined by flameless atomic absorption spectroscopy. When compared with normal adult values, urinary chrom...
متن کاملRemoval of Chromium (VI) in Tannery Wastewater by Bacillus cereus
Bacillus cereus was used to remove Cr(VI) in tannery wastewater containing medium at different initial Cr(VI) concentration, temperature, pH and biomass to get better conditions. At the optimum condition, the Cr(VI) in tannery wastewater was treated by each component of the cells to detect the capacity of the components for the Cr(VI) reduction. Also, the Bacillus cereus was continuous cultured...
متن کاملHexavalent chromium reduction by bacteria from tannery effluent.
Chromium is generated from several industrial processes. It occurs in different oxidation states, but Cr(III) and Cr(VI) are the most common ones. Cr(VI) is a toxic, soluble environmental contaminant. Some bacteria are able to reduce hexavalent chromium to the insoluble and less toxic Cr(III), and thus chromate bioremediation is of considerable interest. An indigenous chromium-reducing bacteria...
متن کاملStudies on Recovery of Chromium Form Tannery Wastewater by 29 Studies on Recovery of Chromium from Tannery Wastewater by Reverse Osmosis
Chromium (Cr) is the most important element used to leather industry is still considered to be the most important industries which pollute the environment by chromium metal. Removal of heavy metals dissolved at low concentrations in water and wastewaters is often a problem that can be solved in different ways. This paper describes a study conducted to determine the recovery of chromium from tan...
