“…Thus, with this high retention and adsorption, Fe could not be effectively leached down the soil profile, hence the low Fe concentration at depths below the surface. Some researchers have reported that soil with coarse texture has a higher infiltration rate than soil with fine texture [14]. The visual inspection of the soil around the dumpsite shows that the soil has fine texture.…”

“…Cu is a strongly adsorbing metal, it can bound very strongly to humus substances, Fe/Al-oxides and other variablecharge particle surfaces due to its large tendency to form complexes, so theoretically it should be well retarded in most type of soils and thus being prevented from leaching to further soil profiles. Xin, [11] and Igloria et al [14] reported that the possibility of formation of complexes between heavy metals and organic matter colloids in solutions, as well as those attached to soil surfaces. Sposito [24], on the other hand, claimed that the effect of these colloids might retard metals transport.…”

Soil contaminated with heavy metals can result to very serious environmental hazard. As a result of this problem, this research was carried out to investigate the concentration of heavy metals (Fe, Zn, Pb, Cu and Cr) in and around Uwelu scrap car dumpsite in Benin City, southern Nigeria. In carrying out this research, a total of 36 soil samples were taken for laboratory analysis. The soil samples were collected at various depths at the dumpsite, and at various horizontal distances from the dumpsite including human settlements close to the dumpsite, in order to ascertain the levels of toxic heavy metal concentration on human living habitat around the dumpsite. The heavy metals in the waste soils samples were sequentially extracted and measured using atomic absorption spectrometry (AAS). The results show that Fe had the highest concentration of 515mg/kg, followed by Zn, 236.8mg/kg, Cu, 78.61mg/kg and Cr, 0.94mg/kg at the dumpsite surface, where all the metals recorded their highest concentration. The level of Fe and Pb were above the Federal Environmental Protection Agency (FEPA) minimum acceptable limit. Besides, the concentrations of these heavy metals decreased with increased vertical depth at the dumpsite and with increased horizontal distance from the dumpsite. Similar

“…Howell and Gawthorne (1987) discussed the important role of organic matter in the retention and behavior of copper. Igloria et al (1997) included the possibility of formation of complexes between heavy metals and organic matter colloids in solutions, as well as those attached to soil surfaces. Sposito (1986), on the other hand, claimed that the effect of these colloids might retard metals transport.…”

A study was undertaken to determine the concentrations of heavy metals in the ground water from landfill leachiest in Chantan, a suburb of Accra. Six wells were excavated from the Dump site and the concentrations for heavy metal such as copper, chromium, arsenic and zinc were monitored using wet digestion technique. HCl and HNO 3 were used followed by atomic absorption spectrophotometry. The heavy metals were quantified using external calibration with standards. Copper had the highest mean concentration of 1.410 mg/l in water from well three (3). This is above the maximum admissible and desirable limit set by the World Health Organization (WHO), an international organization. Chromium recorded the minimum mean concentration of 0.002 mg/l and this was found in wells (2) and (3). Generally, the study revealed that 83.3 % of water samples had mean concentrations below the WHO maximum admissible and desirable limit.
