assessment of heavy metals contamination in urban topsoil from arak industrial city, iran
an increase in heavy metal pollution in the soils of arak due to industrialization and urbanization has become an environmental problem. the region hosts several industrial facilities which are the main source for hazardous wastes which include electric, metal, automotive supply industry, food, machinery, and chemicals. soil samples were collected from these industrial areas in the central and ...
متن کاملEvaluation of background geochemical speciation of heavy metals in overburden topsoil of bituminous sand deposit area, Ondo state, Nigeria
Metals are ubiquitous within the earth crust. However, the exceptional high-level concentration of heavy metals in the soil due to natural or anthropogenic activities and the chemical forms in which they exist determine the level of risk they portend to the environment. This work was aimed at determining the background level of the presence of seven priority toxic metals (Cr, Ni, Pb, As, Cd, Cu...
متن کاملGroundwater Contamination by Heavy Metals in Water Resources of Shiraz Area
Lack of sewage collection systems, percolation of surface waters, and seepage of wells have raised the groundwater table in Shiraz area in the south of Iran. The growing population generates environmental pollution resulting in the degradation of the quality of surface and groundwaters used for agriculture. Inorganic and organic pollutants have been traced in Shiraz water resources. Heavy metal...
متن کاملRisk Assessment and Spatial Modeling of Heavy Metals Contamination in Topsoil around Venarj Manganese Mine by Artificial Neural Networks Method
Background and Objectives: The aim of the present study was to assess the probable heavy metals contamination in topsoil surrounding Venarj mine in Qom province using contamination indices and artificial neural networks method. Material and methods: in order to evaluate the contamination status around Venarj mine in Qom province, 70 soil samples were collected in an area of 22 Km2, and the to...
متن کاملMechanism Analysis and Propagation Model of Heavy Metals Contamination in Urban Topsoil
In order to further research on the polluting condition and spreading features of heavy metals in urban surface soil, this study makes statistical analysis on indexes of 8 heavy metal concentrations. Then Are GIS geostatistical analyst was used for Kriging interpolation of each kind of heavy metal concentration before figuring out the spatial distribution. Firstly, heavy metal contamination was...
