still adsorbed Cu, Pb, Cr, Ni and Zn after desorption experiments in ten di erent soils. In addition, competition adsorption and desorption binary experiments were conducted for evaluating the metal competition in three of the soils. Pb and Cu are the metals adsorbed and retained in higher amounts in all the studied soils.

The values for Cu, Pb, Ni, Cd, and Zn were 0.35, 0.5, 0.6, 0.65, and 0.7, respectively, and these values signify favourable adsorption process. The Freundlich model was successful in analysing experimental data of Ni and Zn ions onto FGCX while that of Pb, Cu, and Cd did not fit the model very well.
The following elements were found in descending concentrations Mn, Zn, Pb, Ni, Cu, Cr, Co, and Cd in Jalalabad and Mn, Zn, Ni, Cu, Cr, Pb, Co, and Cd in Kabul. Except for Ni, all the elemental contents were less than the Canadian permissible limits in residentialparkland soils.

The assessment of the concentration of Cu, Pb, Zn and Cd in groundwater in Enyigba is critical because of presence of numerous Pb – Zn lodes and conditions that are capable of mobilizing the metals into groundwater and pedalogical systems. Groundwater forms one of the major sources of potable water in the area. Analyses of samples of groundwater in the area however reveal that heavy metals ...
The complexation of heavy metals with dissolved organic matter DOM in the environment influences the solubility and mobility of these metals. In this paper, we measured the complexation of Cu, Cd, Zn, Ni, and Pb with DOM in the soil solution at pH 3.7−6.1 using a Donnan membrane technique. The results show that the DOMcomplexed species is generally more significant for Cu and Pb than for ...
