“…But studies from Ghana (Adomako et al 2008;Fianko et al 2010a, b;Nartey et al 2004), Nigeria (Ejechi et al 2007;Jaji et al 2007;Nduka and Orisakwe 2011;Omezuruike et al 2008), South Africa (Zamxaka et al 2004), and Tanzania (Shayo et al 2007) indicated that acidic water is not uniformly found throughout the continent. Water with acidic pH can cause corrosion of the metal pipes used with wells and can release those minerals into wells, potentially causing serious health problems (WHO 2008).…”

Human health depends on reliable access to safe drinking water, but in many developing countries only a limited number of wells and boreholes are available. Many of these water resources are contaminated with biological or chemical pollutants. The goal of this study was to examine water access and quality in urban Bo, Sierra Leone. A health census and community mapping project in one neighborhood in Bo identified the 36 water sources used by the community. A water sample was taken from each water source and tested for a variety of microbiological and physicochemical substances. Only 38.9% of the water sources met World Health Organization (WHO) microbial safety requirements based on fecal coliform levels. Physiochemical analysis indicated that the majority (91.7%) of the water sources met the requirements set by the WHO. In combination, 25% of these water resources met safe drinking water criteria. No variables associated with wells were statistically significant predictors of contamination. This study indicated that fecal contamination is the greatest health risk associated with drinking water. There is a need to raise hygiene awareness and implement inexpensive methods to reduce fecal contamination and improve drinking water safety in Bo, Sierra Leone.

“…The aim of this study was to determine the heavy metal (Cr, Mn, Ni, Cu, Zn, Pb, and Cd) concentrations in the Khoshk River water and sediment in order to identify polluted zones and assess the anthropogenic influence on sediment contamination. The environmental impact of these elements is approved in many papers (for example, Loredo et al 2003;Adamako et al 2008). Results obtained from this study could be used as a baseline on heavy metal concentrations in this river.…”

Heavy metal contents and contamination characteristics of the water and sediment of the Khoshk River, Shiraz, Southwest Iran were investigated. The abundance of heavy metals decreases as Zn > Mn > Cr > Ni >Pb > Cu > Cd in water samples and Mn > Cr > Pb > Ni > Zn > Cu > Cd in sediments, respectively. Based on the enrichment factor and geoaccumulation index values, sediments were loaded with Cr, Zn, Pb, Cu, and Cd. Pearson correlation matrix as well as cluster and principal components analyses and analysis of variance were implemented on data from sampling sites. Based on the locations of sampling sites in clusters and variable concentrations at these stations, it was concluded that municipal, industrial, and domestic discharges in the Shiraz urban area strongly affected heavy metals concentrations in the Khoshk River water and sediment. Results obtained from principal components analysis of sediment samples showed that the high concentration of Ni was mainly from natural origin, related to the composition of parent rocks, while the elevated values of Cr, Zn, Pb, Cd, and Cu were due to anthropogenic activities.

“…Pollution load index values higher than 1 indicate contamination and values close to one indicate similar concentrations of the contaminant in the studied sample and background sample (Adomako et al 2008;Qishlag et al 2007). The calculated PLI in this study was 2.49.…”

“…CF values higher than 1 indicate contamination: in which C sample is the concentration of an element in the sample and C background is the concentration of that element in the background sample. The background sample is obtained by statistical methods by comparing soil samples from the region with local soils not influenced by human factors (Abrahim and Parker 2008;Adomako et al 2008). Table 3 shows the CF for the Sarcheshmeh complex soils area.…”

Assessment of the metals contamination and their grading by SAW method: a case study in Sarcheshmeh copper complex, Kerman, Iran

Studying the distribution of metals in the soil of mineral regions is one of the most important environmental issues. These metals are transferred to the cycle of nature by geogenic and anthropogenic resources, causing serious short-and long-term effects, and posing serious risks for the survival of living organisms. Various mining activities, smelting and beneficiation processes are important anthropogenic factors in the presence of metals in soil, which play a far more effective role in soil pollution than natural factors. Sarcheshmeh copper mine in Kerman is one of the largest copper sulfide mines in the world, for which evaluation and grading of metals contamination has paramount importance due to the high volume of mining. In this study, in order to determine the metal content in the surface soil from the Sarcheshmeh copper complex soils area, 120 surface soil samples were taken from a depth of 30 cm, and analyzed for the metals Pb, Ni, Se, Mo and Zn using the ICP-MS method. Then, the contamination coefficient, enrichment factor and geoaccumulation index of these metals were calculated. Based on expert views on the relative importance of each of the indicators and their final weight, risk assessment and grading by the simple additive weighting (SAW) method was performed. According to the results, the highest risk of pollution was obtained for nickel and the lowest was for selenium.
