“…The difference of Cu sorption in the S-4 soil may be attributed to the higher clay content, carbonate content, and CEC compared to other soils. These results were in agreement with previous reports (Zuhairi, 2003;de Matos et al, 2001). Copper sorption in nine soils was described by the Freundlich (q = K F C 1/n ) and Langmuir (q = K L CQ M / (1+K L C)) sorption models.…”

The correlation results suggest that soils with higher CEC, silt, clay, CaCO3, and organic matter will retain Cu more strongly and in greater amounts than soils that are sandy with lower CEC, CaCO3, and organic matter. pH is not an important impact factor to Cu sorption in experimental soil samples because pH in soils used in this study had a narrow range. The distribution of sorbed Cu varied between nine soils studied and depended on both soil properties and initial added Cu concentration. There are significant differences in the distribution of Cu in each soil with the increase of initial Cu concentration. The predominance of Cu associated with the available fraction, which was over 50% of the total sorbed Cu in most cases, indicates that the change of geochemical conditions might promote the release of Cu back into soil solution thus impacting organisms in the soils. The added Cu has also the tendencies to locate in the residual fraction, which was larger than 5% of the total amount extracted from the four fractions in most soils.

“…Basha et al (2003) have observed this phenomenon when they investigated the effect of agriculture waste on three compacted soils from Malaysia. Consequently, the permeability results reveal that BK is below the minimum limit of formation permeability, which is required to underlay a waste disposal site (Kayabali 1996;Wan Zuhairi 2003). However, the field permeabilities are usually higher than that found in the laboratory (Kayabali andMollamahmutoglu 2000 ''quoted in'' Bahaa-eldin et al 2008).…”

“…Thus, metal ions released in water become distributed into the surroundings through surface or subsurface, lateral, and vertical pathways, especially when lining is absent, improper lining materials are used, or when the lining material is punctured (Agamuthu 2001). The attenuation capability of the soil with respect to movement of the contaminants depends on the chemical properties of soil influence (Wan Zuhairi 2003). Many researches were conducted on the adverse impact of leachate underneath waste disposal (Bahaa-eldin et al 2010;Bahaa-eldin et al 2008;Frid et al 2008;Ahmed and Sulaiman 2001;Benka-Coker and Bafor 1999;Vertacnik et al 1997).…”

This paper aims at determining of inorganic leachate contamination for a capped unsanitary landfill in the absence of hydrogeological data. The 2D geoelectrical resistivity imaging, soil physicochemical characterization, and surface water analysis were used to determine contamination load and extent of selective heavy metal contamination underneath the landfill. The positions of the contaminated subsoil and groundwater were successfully delineated in terms of low resistivity leachate plumes of \10 Xm. Leachate migration towards the reach of Kelang River could be clearly identified from the resistivity results and elevated concentrations of Fe in the river downslope toe of the site. Concentration of Fe, Mn, Ca, Na, K, Mg, Cu, Cr, Co, Ni, Zn, and Pb was measured for the subsoil samples collected at the downslope (BKD), upslope (BKU), and the soil-waste interface (BKI), of the landfill. The concentration levels obtained for most of the analyzed heavy metals significantly exceed the normal range in typical municipal solid waste landfill sites. The measured heavy metal contamination load in the subsoil is in theTaking into consideration poor physical and chemical characteristics of the local soil, these metals first seem to be attenuated naturally at near surface then remobilize unavoidably due to the soil acidic environment (pH 4.2-6.18) which in turn, may allow an easy washing of these metals in contact with the shallow groundwater table during the periodic fluctuation of the Kelang River. These heavy metals are believed to have originated from hazardous industrial waste that might have been illegally dumped at the site.

“…The batch procedure was also reported by Wan Zuhairi [10][11][12] . Four grams of bauxite sample were weighed into the centrifuge tubes with 40 mL of arsenic contaminant mixed for 24 h for different stock solutions at different concentrations, i.e., 5, 10, 20, 50, l00, 200, 300, 400 and 500 ppm.…”
