“…The concentrations of Fe and Mn in all ports were very low compared with the values of LEL (20,000 and 460 µg/g, respectively) and SEL (40,000 and 1100 µg/g, respectively). The values of Fe in the present study were significantly lower than Port Kemblaharbour, Australia (He and Morrison, 2001), while the recorded Mn values were comparable with those reported in Sydney Harbour (Irvine and Birch, 1998) and Victoria Harbour (Wong et al, 1995;Tang et al, 2008) but were much lower than Hamilton Harbour (Poulton et al, 1996). The Fe availability in this study was below that recorded in other harbours around the world (Table 2).…”

The concentrations and distributions of the leachable heavy metals (Co, Cu, Zn, Ni, Cd, Mn, Pb and Fe) were investigated in the fine sediment fractions (Ø3, Ø4 and Ø5) collected from the Egyptian Red Sea Harbors at Hurghada, Safaga and Qusier. The three fractions were the essential heavy metal carriers and were formed the main constituent of the marine sediments with percentages exceed 50% at the most of studied stations. The accumulation sequence of the metal carriers at Hurghada was Ø5 >Ø4> Ø3, however at Safaga and Qusier, it was Ø5 >Ø3> Ø4. Fe and Mn showed the highest values at Safaga (7483 and 306.3 µg/g, respectively) due to the high terrigenous inputs from the different shipment operations and the wastewater effluents. The highest values of Zn, Cu, Ni and Pb were recorded in the marine area off Hurghada ports (330.38, 298.40, 91.4 and 101.02 µg/g, respectively), which attributed to the coastal based activities at Hurghada shipyard and fishing berth. Meanwhile the highest levels of Co and Cd were observed at the old port of Qusier (5.85 and 4.19 µg/g, respectively). The correlation coefficient and principal component analysis (PCA) indicated the anthropogenic sources of Cu, Zn and Pb in front of Hurghada ports. Based on the SQGs, the concentrations of Co, Fe, Mn, Zn and Pb were below the lowest effect level (LEL) with limited severity for Cd, Cu and Ni at Hurghada shipyard but lower than the sever effect level (SEL). The principal component analysis (PCA) showed correlations between Fe, Mn and partially Cd as well as the strong positive correlations for Cu with Zn and Pb suggesting common source of contamination that is likely originated from the terrestrial materials associated with the shipping of ores and coastal activities. According to the Enrichment factor (EF) and the geo-accumulation factor (Igeo), Cu and Pb were the highest enriched elements due to anthropogenic contamination; consequently the studied ports were classified as moderately to highly contaminated by Cu and Pb at Hurghada.

“…Because Pb was previously added to gasoline [43], the use of gasoline-powered machines represents another anthropogenic source of Pb. Furthermore, the [26,34,44]. Therefore, the results of this study clearly demonstrate that agricultural intensification has resulted in an increasing use of phosphate fertilizer and is the main source of metal accumulation in the estuarine sediments of the agricultural region of Chaohu Lake Valley.…”

a b s t r a c tIn this study, the source and risk associated with heavy metals in the estuarine sediments of Chaohu Lake Valley in East China were studied. The results demonstrated that most metal contents (Cd, Pb and Zn) increased continuously from 0.21, 8.05 and 73.76 mg/kg in the substrate to 0.33, 17.20 and 100.22 mg/kg in the surface sediments on average, respectively, in all ten estuaries evaluated. In addition, the high proportion of chemically reactive forms of Cd (18.10-33.60%) implied a moderately high risk, while the risk associated with Pb and Zn was moderate in most estuaries. Enrichment factor (EF) and cluster analysis (CA) were conducted to assess the metal sources. The EF values of Cd, Pb and Zn (4.96, 3.68 and 2.25, respectively) indicated that they had accumulated in the estuarine sediments. Additionally, CA suggested that their primary sources were anthropogenic, namely the extensive use of fertilizers. Therefore, heavy metal pollution due to agricultural intensification in Chaohu Lake Valley should be taken into account during the formation of valley management strategies for the water environment.

“…Risk concentrations of potentially toxic elements are the results of intensive mining activities, metallurgy, agricultural activities, anthropogenic and diverse urban activities. Subsequently, the sediments possess anomalous geochemical and chemical concentrations (Kishe et al, 2003;Liu et al, 2005;Duman, Aksoy and Demirezen, 2007;Liu et al, 2008;Mishra et al, 2008;Tang et al, 2008;Hiller et al, 2010;Wei et al, 2010).…”

The aim of this paper was to analyze and evaluate sediments of selected water reservoirs Počúvadlo, Malá Richňava, Veľká Richňava, Windšachta, in order to determine the concentrations of copper in the monitored water reservoirs in the Banská Štiavnica region. The analyses of the sediment samples were carried out by flow electrochemistry and atomic absorption spectrometry. In the study area, the samples were collected from 2001 to 2010; we found the following concentrations of copper in the range from 1.66 mg.kg -1 to 14.0 mg.kg -1 Cu of dry matter. The copper concentrations in the sediments were well below the risk limit according to "The Methodological Instruction of the Ministry of Environment of the Slovak Republic no. 549/98-2". Based on the calculated dependency index, it is possible to assess the development of changes in the concentrations over the years as highly dynamic, and unsatisfactory for natural environment.
