The emerging environmental problem in the tanning industry is disposal of chromium-contaminated sludge soil. In Walajapet Taluk Vellore District, distribution and mobility chromium soils surrounding tannery waste region were explored. This paper presents soil contamination agricultural lands located SIPCOT Industrial complex near India. 64 samples collected from 15 different villages, analyzed ...

A literature review of experimental and human exposure studies of skin permeation and cutaneous hypersensitivity reactions evoked by chromium was carried out to provide a basis for making a risk assessment of chromium as a soil contaminant. In vitro and in vivo studies demonstrated that 1 to 4% of the applied dose of hexavalent and trivalent chromium to guinea pig skin penetrated skin within 5 ...

Little knowledge is available about the influence of cation competition and metal speciation on trivalent chromium (Cr(III)) toxicity. In the present study, the effects of pH and selected cations on the toxicity of trivalent chromium (Cr(III)) to barley (Hordeum vulgare) root elongation were investigated to develop an appropriate biotic ligand model (BLM). Results showed that the toxicity of Cr...

Abstract Fish is generally appreciated as one of the healthiest and cheapest source of protein and it has amino acid compositions that are higher in cysteine than most other sources of protein. Heavy metals are natural trace components of the aquatic environment but their levels have increased due to industrial wastes, geochemical structure, agricultural and mining activities. All these sources...

PURPOSE In this study, a novel and ecological alternative have been developed to treat soils contaminated with hexavalent chromium coupling two well-known systems: electrokinetic remediation and permeable reactive biobarriers. The electric field promotes the electromigration of the hexavalent chromium oxyanions towards the anode. The biobarriers were placed before the anode electrode, in order ...
