Abstract Purpose The study aims to assess the impact of human activity on content and migration trace elements in soil profiles various physico-chemical properties. research hypothesis assumed that related functioning buildings, agriculture, industry communication negatively affected element contents properties soils a selected urban area (the Grudziądz Basin). Materials methods Seven exposures...

Cr, Co, Cu, Zn, Cd and Pb in the bottom sediments from 93 sites at Quiberon bay were analyzed by Inductively Coupled Plasma Mass Spectrometry (ICPMS) after acid extraction. The ranges of the concentration in the sediments are as follows: 27.3 μg/g (Cr), 11.6 μg/g (Co), 13.8 μg/g (Cu), 42.0 μg/g (Zn), 0.08 μg/g (Cd) and 17.8 μg/g (Pb). Potential contamination of the bay was assessed by Igeo and ...

In the present paper, an investigation on natural and anthropic radioactivity heavy metals content in a basalt aggregate for concrete from Sicily, Southern Italy, was performed as case study. particular, evaluation of specific activity radium-226, thorium-232, potassium-40 caesium-137 radionuclides by using High-Purity Germanium (HPGe) γ-ray spectrometry, together with estimation several indexe...

air pollution is today a major problem for modern societies. it has long been recognized as a potentially lethal form of pollution. increasing pollution levels due to rapid urbanization and growth in emission related to vehicular transportation are now caused major concern. the mobilization of heavy metals into the biosphere by human activities has become an important process in the geochemical...

pollution of water and soils by heavy metals is an emerging problem in industrialized countries.the present study was conducted to investigate the heavy metals concentration in water and sedimentsamples from ship breaking sites of sitakunda to assess the potential ecological risk posed by heavy metalusing different methods. heavy metals concentration was analyzed by atomic absorption spectrosco...

background: sediments are inseparable fractions of wetland ecosystems that work as a his-torical archive in the process of recording heavy metal aggregation changes. this study was carried out for assessing co, ni, and zn in sediment samples of mighan wetland using geo-accumulation index in 2013. methods:the sediment samples were taken from 11 stations. the samples were subjected to bulk digest...

the purpose of this study was the introduction of seed accumulation index as a new approach in the evaluation of soil seed bank consistency in the populus caspica in noor reserved forest park. sampling were made above ground vegetation at peak vegetation cover during june 2010 by systematic- selective method. soil samples were collected during late june, late november and early february by hamm...

The cement industry is considered as a major source of heavy metals pollution in topsoil. This study aims at measuring the metal contamination level vicinity Shiraz factory, and assessing ecological environmental risks associated with factory's activities surrounding To do so, 10 samples soil were taken from around factory depth 0-10 cm concentration some including Al, Cd, Ni, Pb was measured. ...

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...
