Investigation of heavy metal mobility and availability by the BCR sequential extraction procedure: relationship between soil properties and heavy metals availability
Posted on 4. December, 2014.
Surface soil and corn cob samples were collected from 15 different agricultural fields of Çanakkale, Turkey, and were analysed to determine the concentration of Cd, Cu, Mn, Ni, Pb and Zn. BCR sequential extraction was used to extract the binding forms of the metals in the soil samples.
Chemical speciation of Zn in acidic soils: suitable soil extractant for assessing Zn availability to maize (Zea mays L.)
Posted on 13. November, 2014.
Zinc is an essential micronutrient for plants, animals and humans. Being a structural constituent or a regulatory co-factor, it influences the activities of several key enzymes involved in important biochemical processes.Crop plants obtain their necessary Zn from soil.
Fractionation, mobility and multivariate statistical evaluation of metals in marine sediments of Cape Town Harbour, South Africa.
Posted on 15. August, 2014.
In this study, the distribution of possible chemical forms of Al, Si, Sn, Pb, Zn, Fe, Hg, Cd and Cu in marine sediments of Cape Town harbour was investigated using a modified Tessier’s sequential extraction procedure and ICP-MS and ICP-AES for heavy metals determination.
Mercury contamination in five owl species from Iran
Posted on 5. August, 2014.
Mercury occurs naturally in the environment but anthropogenic sources, such as fossil fuel combustion, non-ferrous metal production and waste incineration, have been suggested to contribute significantly to the mercury contamination
Evaluation of copper and vanadium concentration in the soft tissue of Tylosurus crocodilus in Bahregan region, Persian Gulf
Posted on 25. June, 2014.
The Persian Gulf is a shallow water body, with an average depth of 35–40 m and an area of about 240 km2 which is connected to oceanic waters through the Strait of Hormuz. In recent years, due to various environmental events including the world’s largest oil loss in 1991, ship traffic, oil transportation and other pollution, the region is in crisis.
Evaluation of genotoxic and oxidative stress response to dimethoate in freshwater fish Channa punctatus (Bloch)
Posted on 11. June, 2014.
Dimethoate (O, O-dimethyl S-methyl carbamoylmethyl phosphorodithioate) is a broad-use systemic organophosphate insecticide. It exerts acute toxic effects to pests by irreversible inhibition of the cholinesterase enzyme from breaking down acetylcholine.
Hazardous elements speciation in sandy, alkaline coal mine overburden by using different sequential extraction procedures
Posted on 4. June, 2014.
Worldwide surface coal exploitation has made an impact on the environment by producing massive overburden stock piles with very heterogeneous physico-geochemical properties.
Influences of natural zeolite on speciation of heavy metals during rotary drum composting of green waste
Posted on 9. May, 2014.
The water hyacinth (Eichhornia crassipes) is a free floating aquatic weed originating in the Amazon in South America and has been considered as the most noxious plant species in the world.
Effect of organic amendments on phytoavailability of nickel and growth of berseem(Trifolium alexandrinum) under nickel contaminated soil conditions
Posted on 28. March, 2014.
Since the green revolution, man-induced activities have redistributed many heavy metals from the earth’s crust to all environmental compartments. Therefore, environmental contamination by heavy metals has become a growing environmental risk at a global scale.
