Jun 05, 2012 · Results show that in wetland soils pedogenic processes differentially distribute contaminants amongst the redoximorphic features. The distribution is affected by landscape position and water table influence. At the pedon scale, there is an enrichment of As, Cd, Pb, and Zn in surface horizons, suggesting that upward flux of contaminants is occurring.
Jun 29, 2017 · No zinc up to 50% in large Quantity in Naija. know of none yet. from zurak,gimbi,jawando, to pinot and close to Bauchi where we are doing heavy Zn n pb mining, all the above 50% Zn na wash. Some of us have learnt the hard way . please be careful. 99% of what Jlow have said is right.
EDTA solutions were found to dissolve large quantities of Pb (%) and Zn (%) from the mine tailings. Zinc dissolution was also high using a solution of ammonium thiosulphate (%) and Ag dissolution was only notable using an ammonium thocyanate solution (%). The data indie that chemical leaching of the Cannington mine tailings ...
The heavy metal (Pb, Zn, Cr, Cu, Cd, and Hg) concentrations in the A horizon and C horizon soils, collected around the Pb/Zn mining and smelting area of Shuikoushan in Hunan, China, were investigated, and the Pb isotopic compositions were also determined to identify the potential origin of Pb in the A horizon soil.
The total concentrations of Cd, Pb, Cu and Zn in both contaminated soils exceeded the maximum permissible limits set by Ministry of Environmental Protection for soil. Under the optimum conditions, 35% for Cd, 64% for Pb, 25% for Cu and 14% for Zn from garden soil and 97% for Cd, 87% for Pb, 46% for Cu and 33% for Zn from paddy soil were leached ...

Cassava leaf and tuber samples were collected from four different farmlands around galena mining site in Ishiagu, Ebonyi state, Nigeria. These samples were monitored for heavy metals using atomic absorption spectrometer. Metals studied were Pb, Mn, Ni, Fe, Cr, Cd, Zn, and Cu. The concentration range of these metals in cassava tubers were found to be 1027mg/kg Cu, 8693mg/kg Zn, .
