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.

Nickel Chemical Transformation in Polluted Soils as Affected by Metal Source and Moisture Regime

Posted on 22. September, 2010.

It is important to examine chemical speciation, transformation and availability of heavy metals in polluted soils under different moisture conditions. The present study was, therefore, undertaken to study the fate of added Ni in different soils polluted with sludge or inorganic salt under field capacity and flooding moisture regimes.

Influence of Nutrient Addition on Growth and Accumulation of Cadium and Copper in Lemna Gibba

Posted on 22. September, 2010.

The objective of this study was to determine whether nutrient enrichment enhances the metal tolerance of floating macrophytes, which would therefore enable the growth of floating vegetation in constructed wetlands at metal concentrations that would otherwise inhibit plant viability.

Phosphorous Sorption Characteristics of the Bronx River Bed Sediments

Posted on 22. September, 2010.

Jingyu Wang and Hari K. Pant, who are both based in New York, consider how the degradation of water quality of the Bronx river may be influenced by an increased flux of phosphorus which is a major nutrient for algal growth.. Algal blooms and oxygen depletion within the river have degraded the water quality, endangered fishing, and limited recreational use.

Interactions Between The Chemical Forms And Behaviour Of Toxic Compounds And Their Subsequent Biological Uptake, Metabolism And Ecological Fate

Posted on 19. July, 2010.

Given the environmental impact of the recent BP oil spill in the Gulf of Mexico, it is important to improve our understanding of the interactions between the chemical forms and behaviour of toxic compounds and their subsequent biological uptake, metabolism and ecological fate.
