Metal (Cr, Co, Cu, Zn, Cd, Pb, Ni) and metalloid (As) accumulation was studied in roadside soil and wild rat (Rattus sp.) samples from near a Pb-Zn mine (Kabwe, Zambia) and the capital city of Zambia (Lusaka). The concentrations of the seven metals and As in the soil samples and Pb in the rat tissue samples were quantified using atomic absorption spectroscopy. The concentrations of Pb, Zn, Cu, ...

Abstract Drill core samples from the Profitis Ilias Pb-Zn-Cu-Ag-Au vein mineralization on Milos Island, Greece provide new insights into (i) metal sources, (ii) primary vertical metal(loid) distribution, and (iii) supergene enrichment processes in a transitional shallow-marine to subaerial hydrothermal environment. Metal contents of unaltered altered host rocks combined with Pb isotope analyses...

The Tullacondra Cu-Ag deposit is located on the southern margin of Lower Carboniferous Irish Midlands orefield and contains historical reserves approximately 4.2 Mt at 0.7% Cu 27.5 ppm Ag. hosted within hanging wall a feeder fault, EW-trending Fault, where sulfides sulfosalts containing elevated Cu, Ag, As, Sb deposited, whereas Zn Pb are nearly absent. deposition in took place along bedding be...

Three chemical immobilization materials, agricultural limestone (AL), mineral rock phosphate (RP), and diammonium phosphate (DAP), were evaluated using solute transport experiments to determine their ability to reduce subsurface heavy metal transport in a smelter contaminated soil. Percent reductions in metals transported were based on comparison with cumulative totals of metal species eluted t...

Present study consists geochemical variations and spatial distribution of trace elements (Fe, Mn, Cr, Co, Cu, Ni, Pb and Zn) of the ocean floor sediments collected along the continental shelf off East coast Tamil Nadu (Chennai to Velanganni) during the 2009 southwest monsoon period. Results indicate sand dominance with abundant calcareous debris and shell fragments. Normalisation of trace metal...

The objective of this study was to investigate the concentration and spatial distribution patterns of six potentially toxic heavy metal elements (Mn, Zn, Cr, Pb, Cu and Ni) in bus station dusts in the Xifeng district of Gansu province, NW China. The contents were analyzed for Mn, Zn, Cr, Pb, Cu and Ni by using S8 TIGER Brochures wavelength dispersive X-ray fluorescence spectrometry. Geoaccumula...

The Mayuan Zn-Pb deposit on the northern margin of Sichuan Basin is rich in resources. Additionally, a large amount bitumen observed outcrops, and these deposits represent key template for exploring migration hydrocarbon fluids metal elements within an ancient oil reservoir. In this study, chemical experimental method was used to extract adsorbed from chosen five groups samples, mathematical st...

concentrations of six heavy metals including cr, mn, ni, pb, v and zn were determined in topsoil (from 47 grid cells), surface water (4 streams) and groundwater (8 wells and 4 qanats) from an agriculturalarea located at south part of the iranian capital, near the tehran oil refinery. concentrations of the elementswere measured using flame and flameless atomic absorption spectrometry. based on t...

Onzon-Kanbani area is a western flank of Mogok Metamorphic Belt where gold mineralization is hosted as auriferous quartz-vein with epithermal low-sulphidation characters. Mineralization is closely associated with NE-SW trending fracture or shear zone probably related to the dextral movement of the Sagaing Fault system. Mineralization related hydrothermal alteration is developed as narrow zones ...
