This paper describes the concentration of selected heavy metals (Co, Cu, Ni, Pb, and Zn) in the Mamut river sediments and evaluate the degree of contamination of the river polluted by a disused copper mine. Based on the analytical results, copper showed the highest concentration in most of the river samples. A comparison with Interim Canadian Sediment Quality Guidelines (ICSQG) and Germany Sedi...

introduction landfilling sites of wastes including big volume of waste. in recent years lack correct management caused that landfilling sites of municipal waste taken as one of main source pollution effluence at environmental. from between diverse contaminants heavy metals because of environmental stability, biogeochemical process, poison biology, sorption and desorption, redox potential, sedim...

Radiochemical and elemental analysis of clay soils collected from different locations within Ekiti State have been performed in this study using gamma and XRF spectrometric measurements. The results of this study show that the mean concentrations of uranium ranged from 2.2 ± 1.0 mg/kg to 3.2 ± 1.1 mg/kg, that of thorium ranged from 4.0 ± 0.5 mg/kg to 5.7 ± 1.7 mg/kg, while potasium presented in...

The "Agios Philippos" mine in the Kirki region (NE Greece) has been abandoned in 1998 after half a century of ore exploration without a reclamation or remediation plan. This article aims at elucidating the potential environmental risks associated with this site by quantifying pollution in tailing basins, stream waters, stream sediments and agricultural fields. Concentrations of heavy metals in ...

Bogra city is highly susceptible to environmental pollution due to over population, rapid industrialization and urbanization during the last decades. A study was conducted to determine heavy metals (Cu, Zn, Pb, Cr, Cd and Ni) pollution level and physicochemical properties in the soils of Bogra city. The concentrations of heavy metals in 14 soil samples were determined by using an Atomic Absorpt...

Sediments represent a critical compartment of marine coastal ecosystems due to the toxic and long-lasting effects contaminants buried therein. Here, we investigated properties surficial sediments in front Southern Marche Region coast (Central Adriatic Sea, Italy). The grain size was determined by X-ray sedigraphy. TN OC contents were elemental analysis. concentrations Al, Fe, Mg, K, S, Ca, Ti, ...

With the rapid development of economy, heavy metal soil pollution causes ecosystem deterioration and raises serious concerns. Topsoil samples (n = 205) were collected to investigate characteristics, risk levels, sources metals in topsoil eastern Tibet. Heavy contents, such as As, Hg, Pb, Cr, Mn, Mo, Ni, Cu, Zn, Cd, tested, potential analyzed using correlational principal component analysis. The...

The aim of the study was to assess quality agricultural soils, which accumulate additional amounts heavy metals from fertilization and modify their bioavailability, with use interdependencies between biological chemical properties conditioned by distance communication routes. Our results indicated that had an impact on enzyme activity in soils accumulation significantly related edge road, locat...
