Phytoremediation design based on field scale assessment of chromium uptake by crops and native plants in and around Rania-Khan Chandpur Cr-contaminated site, India.

We designed a phytoremediation plan for the chromite ore processing residue (COPR) site based on the field-scale assessment of chromium (Cr) uptake by plants thriving in Rania and Khan Chandpur villages, India. We performed a series of investigations to: (i) estimate the land use using unmanned aerial vehicles, (ii) collect plant samples for ICP-MS analysis for Cr concentration in their root, shoot, and grain, (iii) develop suitable biomass management strategies for Cr-laden plant biomass. We found the maximum Cr-concentrations of 196.

Field-scale assessment of soil, water, plant, and soil microbiome in and around Rania-Khan Chandpur Chromium contaminated site, India.

Rania-Khan Chandpur site, (Kanpur Dehat, Uttar Pradesh, India), one of the highly Chromium (Cr) contaminated sites in India due to Chromite Ore Processing Residue (COPR), has been investigated at the field-scale. We found that the area around the COPR dumps was hazardously contaminated with the Cr where its concentrations in the surface water and groundwater were > 40 mgL, its maximum contents in the COPRs and in the soils of the adjoining lands were 9.6 wt% and 3.

Hybrid electrocoagulation and laccase mediated treatment for efficient decolorization of effluent generated from textile industries.

Enzymatic (laccase mediated) decolorization of dyes remains inefficient for recalcitrant dyes, which can be better handled by electrocoagulation (EC). However, EC is energy intensive and produce large amount of sludge. In light of the same, present study offers a promising solution for the treatment of textile effluent meeting surface discharge norms, using hybridization of enzymatic and electrocoagulation treatment.
