“…In addition, the higher electrical conductivity observed at S 2 could be attributed to the relatively low DO concentration and revealed high negative correlation to each other (temp/DO: r= -0.771). This result is in accordance with the works of Phiri et al [21] and Okafor [22] who reported that high EC contribute for reduction of DO concentration in the given water bodies.…”

“…Similarly, negative correlation coefficient "r" between elemental pairs of Hg/pH, Cd/pH and OM/DO represented the inverse relationship between those parameters which were consistent with the works of Kar et al [23] and Nirmal et al [24]. Generally, most of the physico-chemical parameters had higher correlation coefficient and can contribute for higher concentration of metals in aquatic ecosystems which is inconsistence with the works of Igbinosa and Okoh [18], Okafor and Opuene [22], and Kar et al [23].…”

“…pairs of Hg/DO, Hg/TDS, Cr/ OM, Zn/Tem, Zn/TDS, Zn/OM, Cd/pH). The higher values of those physico-chemical parameters contribute for higher concentration of metals as suggested by Igbinosa and Okoh [18] and Okafor and Opuene [22]. This implies that there are potential sources of pollutant to the lake from various directions particularly from the northern side of the lake.…”

“…Natural geochemical background is characterized by low concentrations of heavy metals, from a fraction of a microgram to several hundred micrograms per liter of water [1,2]. Heavy metals find their way into lakes due to human activities, as anthropogenic contamination, which can result in dramatic increases in their concentrations [3,4]. The most common sources of heavy metal pollution are industrial activity, like coal power plants, steelworks or cement factories; through the use of fertilizers; and vehicle emissions.…”

Abstract:The article presents detailed geostatistical analysis of spatial distribution of lead and zinc concentration in water, suspension and bottom sediments of large, urban lake exposed to intensive anthropogenic pressure within a large city. Systematic chemical measurements were performed at eleven cross-sections located along Czerniakowskie Lake, the largest lake in Warsaw, the capital of Poland. During the summer, the lake is used as a public bathing area, therefore, to better evaluate human impacts, field measurements were carried out in high-use seasons. It was found that the spatial distributions of aqueous lead and zinc differ during the summer and autumn. In summer several Pb and Zn hot-spots were observed, while during autumn spatial distributions of Pb and Zn were rather homogenous throughout the entire lake. Large seasonal differences in spatial distributions of Pb and Zn were found in bottom sediments. Autumn concentrations of both heavy metals were ten times higher in comparison with summer values. Clear cross-correlations of Pb and Zn concentrations in water, suspension and bottom sediments suggest that both Pb and Zn came to Czerniakowskie Lake from the same source.

The concentrations of eight trace elements, Cadmium (Cd), lead (Pb), iron (Fe), zinc (Zn), manganese (Mn), copper (Cu), mercury (Hg) and arsenic(As) in sediment and water were assessed in four artisanal and small-scale mining(ASM) localities in the Amansie West District (6°282 N 1°532 W) of Ghana along two river courses from May 2011 to July 2011. Triplicate water and sediment samples were randomly taken at five different points at each of the localities and the elements determined using Atomic Absorption Spectrophotometer (AAS ). Using the Geoaccumulation Index( I geo ) assessment, the sediments were found to be polluted to different degrees with Cu (Uncontaminated to moderately contaminated/Moderately contaminated), Hg (Uncontaminated to moderately contaminated/Moderately contaminated) and As (Moderately contaminated/Moderately to strongly contaminated). The Enrichment Factor (EF) indicated human influence -artisanal mining activities on the sediment concentration of Cd and Pb for all the localities and only some of the localities for the rest of the trace elements. The elements are major sediment pollutants ( EF > 2) in one or more of the localities. The I geo and EF gave diverse status of the sediment qualities of the localities. Cd, Pb, Hg and As water concentrations in the four artisanal mining localities were all found to be above the WHO maximum acceptable of levels for drinking water. Inhabitants in the mining localities face the risk of getting various diseases by drinking the waters contaminated with the trace elements.
