The present study investigates the concentration of Pb, Cd, Ni, Zn, and Cu in the paddy field soils collected from Tumpat, Kelantan. Soil samples were treated with sequential extraction to distinguish the anthropogenic and lithogenic origin of Pb, Cd, Ni, Zn, and Cu. ELFE and oxidizable-organic fractions were detected as the lowest accumulation of Pb, Cd, Ni, Zn, and Cu. Therefore, all the heav...

Exponential industrialization and rapid urbanization have resulted in contamination of soil by metals from anthropogenic sources in Dongguan, China. The aims of this research were to determine the concentration and distribution of various metals (arsenic (As), cadmium (Cd), chromium (Cr), copper (Cu), mercury (Hg), nickel (Ni), lead (Pb) and zinc (Zn)) in soils and identify their potential heal...

Heavy metals in soils are of great environmental concern, in order to determine heavy metal content in the surface soil from the vicinity of an abundant railway servicing workshop and evaluate the contamination levels, 40 surface soil samples were collected and analyzed for Cu, Zn, Cd, Pb, Fe and Ni contents using atomic absorption spectroscopy. Soil texture, conductivity, pH, total organic con...

Increasing air pollution levels due to rapid urbanization and growth in vehicular emission have become a major source of concern. As a result, research on air pollution in urban environments has largely focused on road deposited dust. In the present study, road deposited dust samples collected from the Ketu-South District, Volta Region in Ghana were analyzed for heavy metals (As, Cr, Cu, Mn, Ni...

The Chah-Shaljami polymetal ore deposit contains heavy metal anomalies in various mineralization zones. Geochemical distribution and correlation of elements in surficial soilsindicate that sulfide, sulfate, sulfosalt and silicate mineral occurrences (e.g. Pyrite, chalcopyrite, galena, sphalerite, molybdenite, enargite, hornblend and biotite) in mineralization and stockwork zones resulted in the...

20 soil samples collected from the vicinity of the Khash Cement plant, Iran, were analyzed for As, Cd, Co, Cr, Cu, Mn, Mo, Ni, Pb and Zn using ICP-OES. The results revealed that the metal distribution were in a fluctuating manner considering various distances and direction from the cement facility. However, it was observed that the mean concentration of the soil samples has no special trend wit...

In this study, the quality of sediment and surface water in two natural wetlands, Paca Tragadero, central region Peru was evaluated using pollution indices, including geoaccumulation index, pollutant load modified degree, potential ecological risk site rank for four heavy metals. Principal component analysis used to identify metal contaminant sources. The determination Fe, Zn, Pb, As performed ...

The Tongon mine generates millions of tons waste rock and tailings, which are stored in landfills the vicinity mine. These tailings contain arsenic. risk soil contamination this area is evident. This study assesses arsenic soils around health risks to local population. Soil samples were taken from plastic bags other materials used as working tools. Arsenic concentrations determined by inductive...

As a primary sink of pollutants, urban soil heavy metal pollution and its influence on residents ecosystems has been becoming one the most important environmental problems. In present study, four indices, Geoaccumulation index (Igeo), improved Nemerow (IMN), degree contamination (mCd), security (CSI), as well potential ecological risk (RI), were used to evaluate individual or integrated for sam...

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...
