Aghdarband coal mine, located in NE of Iran, with annual coal and waste production capacity of about twenty million and six thousand tons, respectively, causes the increase of the concentration of some heavy metals in the soil and surrounded sediments. This paper deals with geochemical distribution and environmental effects of the heavy metals on the sediments around the mine, using geochemical...

the  present study was aimed  at comparing the ability of three crop plants for phytoremediation of zinc (zn) and nickel (zn) from soils. a factorial (3×2×3) experiment based on rcbd was  used to compare the treatments,  and was repeated three times. the first factor was crop type (wheat, clover and rapeseed), the second factor was heavy metal types (zinc (zn) and nickel (ni)) and the third fac...

Jharia coalfield is one of the most important sources of coking coal in India. Coal mining activities in this coalfield have significantly caused mineralisation of surface and ground water; there-by adversely affecting it’s quality and utility. Several trace elements may be present in mine water released from various mining and processing operations. In this paper, an attempt has been made to a...

for the first time this study reported the success of using nanocrystalline hexagonal close-packed (hcp) nickel (ni) modified composite graphite (cg) electrode (hcp-nano ni/cg) for the electrocatalytic oxidation of glycerol in alkaline medium (0.1 m koh). the hcp-nano ni/cg electrode had an improve response and specificity on the electrocatalytic oxidation of glycerol over the bare cg. the elec...

Assessment of the ecological quality of theMinho estuary (Northwest Iberian Peninsula) based on metal concentrations in sediments and in Corbicula fluminea The concentrations of metals (Cd, Cr, Cu, Fe, Ni, Pb and Zn) in sediments and the soft tissues of Corbicula fluminea from the Minho estuary (Northwest Iberian Peninsula) were determined to assess the spatial variation of metal bioavailabilit...

This study investigated the effects of sodium azide pre-treatment Vernonia amygdalina stem cuttings on bioaccumulation heavy metals in a waste engine oil-contaminated soil. Top soil was collected and sun-dried to constant weight. Soil then mixed thoroughly with oil (WEO) weight basis, obtain 4% w/w concentration. Soils were left attenuate for 1 week (WAP). Sodium solution prepared concentration...

this work studies the biosurfactants production which enables the diesel biodegradation byusing mixed microbial consortia from polluted sites. it was carried out by culturing three microbial consortia(named as xa, xb and xc) obtained from polluted soils, and enriched in diesel as sole carbon source.batchexperiments were done to study the effects of three variables (temperature,hydrocarbon conce...

ABSTRACT- A pot experiment was conducted to elucidate the effects of single and co-inoculation of maize plant with Bacillus mycoides and Micrococcus roseus, indigenous to HMs contaminated soils, on the plant growth and uptake of essential nutrients and Ni by maize in the soil polluted by 250 and 500 mg Ni kg-1. At each level of Ni contamination, shoot dry weight and nutrients uptake significant...
