Phytostabilization aims to reduce environmental and health risks arising from contaminated soil. To be economically attractive, plants used for phytostabilization should produce valuable biomass. This study investigated the biomass production and metal allocation to foliage and wood of willow (Salix viminalis L.), poplar (Populus monviso), birch (Betula pendula), and oak (Quercus robur) on five...

soil washing by mobilizing is one of in-situ techniques for soil decontamination. applying this technique to the contaminated soils could be followed by many environmental problems. therefore, it is important to study the effective factors on removal of heavy metals from different forms. in the present research, the forms of zn, pb, and cd in three contaminated soils from the zinc-lead smelting...

This study aims at determining the elemental concentrations of Cu, Zn, Cr, Pb, Ni, Co and Cd in the sediment samples from Odo-Owa and Yemoji streams in Ijebu-Ode Local Government Area (L.G.A), South Western (SW) Nigeria, using Atomic Absorption Spectrophotometer and comparing the concentration of these metals in the two streams with other studies and with acceptable concentration values for met...

Background: Marine pollution is a global environmental problem that its monitoring by ideal biomonitors is of great importance. Marine organisms, especially mussels, have the ability to accumulate metals from the environment they can be considered as a biomonitoring agent. Methods: In this study, concentrations of heavy metals were measured in Saccostrea cucullata collected from seven sites on...

this study investigates the status of heavy metals contaminations in urban soils of ostrava inthe czech republic. the main aim of this study was determination of concentration of cd, pb, zn, cu, mn,v and hg, assessment of contamination levels of metals in urban soils and verification of potential source ofmetals contamination. soil samples were collected from soil layer of 20 cm and metals were...

In this study, some metals (aluminium, chromium, copper, iron, manganese, lead, zinc and vanadium) and metalloid (silicon) were determined in water, sediment and some tissues of fish Cyprinus carpio from Mogan Lake. Fish samples were caught in March 2007. As a result of the examination of metals in the water aluminium has the lowest and silicon has the highest concentration. In sediment samples...

concentrations of heavy metals (ni, co, zn, cd, pb and cu) in the reservoir of shahid rajaeidam, one of the main water reservoirs in north part of iran, were determined using a differential pulse polarography(metrohm 797 va) and compared with the national and international specified maximum contaminant levels(mcl) for different purposes of water use. the results showed that concentrations of cd...

Background & Aims of the Study: Due to the increased human activities around the Agh Gel wetland, this study aimed to measured accumulations of heavy metals (Ni, Pb and Zn) in the surface sediment samples taken from this wetland. Materials & Methods: Samples were taken from 10 stations and exposed to bulk digestion and chemical partitioning. Finally, Ni, Pb and Zn conce...

The Haft-Savaran Pb-Zn mineralization zone with the lower Jurassic age is located in the southern basin of Arak and Malayer-Isfahan metallogenic belt of Iran. Based upon the geological map of the Haft-Savaran area, the sandstone and shale of lower Jurassic are the main rocks of Pb-Zn deposit. In this area, 170samples were taken from 33 boreholes, and44 elements were measured by the ICP-MS metho...
