“…However, one of the most important environmental issues today is water contaminated with heavy metals because of strong toxicity even at low concentrations (Marcovecchio et al, 2007). Water contamination with light and heavy metals are mainly determined by natural (i.e., weathering, erosion of bed rocks and ore deposits) and anthropogenic (e.g., mining, smelting, industries, agriculture and waste water irrigation) processes (Ettler et al, 2011;García-Lorenzo et al, 2011;Muhammad et al, 2011;Sracek et al, 2011). These processes degrade water quality and impair their use for drinking, domestic, agricultural and industrial purposes (Krishna et al, 2009).…”

This study was carried out in Igun-Ijesha, Osun State, Nigeria to determine the likely hotspots of water contamination for future treatment trials. Water quality analyses were based on physico-chemical and heavy metal parameters of surface and ground water collected from the study community. A total of thirty-eight water samples were collected between September 2012 and February 2013 and analyzed using standard procedures. Concentrations of heavy metals were determined using Atomic Absorption Spectrophotometer. Results showed that water samples within the gold mining community are contaminated and the hydrochemistry varied with seasons. The values of magnesium, turbidity, total dissolved solids, electrical conductivity and pH during the period of sampling ranged 3.1-42.1 mg/L, 0-150 NTU, 30-560 mg/L, 80-1192 µS/cm and 5.95-8.55 respectively. Chloride, nitrate, phosphate, sulphate and sodium data were within the stipulated limits set by the Nigerian Standards for Drinking Water Quality (NSDWQ). Heavy metal contents of the groundwater were generally higher than those from surface water sampled within the mining district. The values of arsenic, cadmium, chromium, copper, lead, manganese, nickel and zinc, ranged from 0.01-1.20, 0.05-0.52, 0. 80-34.80, 0.09-4.30, 0.09-8.30, 0.05-3.94, 0.05-19.6 and 1.80-29.90 mg/L respectively. Most of the listed metals have values exceeding the international and national recommended limits. The daily intake of water in the study area poses a potential health threat from long-term exposure to heavy-metals. The study suggests that water safety plans should be developed to safeguard water resource and public health within the mining community.

“…Physical, chemical and biological characteristics of water are considered as a major health controlling factor and the state of disease in the living organisms (Kazi et al, 2009). Water contamination with light metal (LM) and heavy metal (HM) are mainly determined by natural (i.e., weathering, erosion of bed rocks and ore deposits) and anthropogenic (i.e., mining, smelting, industries, agriculture and waste water irrigation) processes (Ahmet et al, 2006;Ettler et al, 2011;García-Lorenzo et al, 2011;Khan et al, 2008;Muhammad et al, 2010Muhammad et al, , 2011aSracek et al, 2011).

“…Copper may bind to organic matter and iron oxides in river sediments (Yu et al 2001). High Cu concentrations were reported in river sediments close to industrial and municipal waste sources (Chen et al 2012) and mining activities (Sracek et al 2012). Therefore, high Cu concentrations in the ZM sediments probably partly originate from a copper industry situated upstream of the sampling site.…”

Purpose The main objective of this study was to evaluate the concentrations and seasonal variations of trace elements in surface sediments of three major rivers in Serbia-the Danube, the Zapadna Morava (ZM), and the Južna Morava (JM)-according to sediment quality guidelines. The ZM and the JM create the Velika Morava River, one of the most important tributaries of the Danube, which has been characterized as a source of heavy metal pollution. Materials and methods The total concentrations of 15 elements (Al, As, B, Ba, Co, Cr, Cu, Fe, Hg, Mn, Mo, Ni, Pb, Sr, and Zn) were determined in surface sediments (0-15 cm depth) collected during three seasons using inductively coupled plasma spectroscopy (ICP-OES). Principle component analysis (PCA) was used to identify the main variations in metal concentrations and grain size distribution. Scanning electron microscopy/energy dispersive X-ray spectroscopy (SEM-EDS) was used for grain analysis. Results and discussion PCA and three-way MANOVA results showed significant differences in element concentrations and grain size distribution between the rivers, and significant seasonal differences for each river. The concentrations of Cu and Ni exceeded sediment quality guideline levels in the ZM and the Danube, respectively, while excess Hg was detected in all three rivers. Concentrations of Al, Ba, Cu, Fe, Sr, and Zn significantly varied between seasons in the Danube and the ZM, being the highest in the summer. In the JM, concentrations of Al, As, Fe, Mn, and Zn varied with season, with the lowest values in the summer. The ZM had the highest percentage of silt and clay, and SEM-EDS analysis of ZM sediments showed associations of Cu with carbonate hydroxides and/or iron oxides in particles <100 μm. The results suggested that mining and industrial activities could be the sources of increased levels of metals in the ZM. Conclusions The sediments collected from the ZM were considerably more polluted with heavy metals in comparison to the JM. Cu was identified as a heavy metal of greatest risk in the ZM. The ZM was indicated as the main source of heavy metal delivery in the Velika Morava and Danube rivers. It is suggested that the main factors influencing pollution levels could be anthropogenic sources and industrial and mining activities, while seasonal changes might be related to dynamics of water flow and morphological characteristics of the two tributary rivers.
