“…The concentrations of heavy metals Pb, Cd, Cu and Zn in soil samples of other locations are different and summarised in Table 3. This table shows that the highest records of the heavy metals values are observed in Isfahan, Iran and Tamilnadu, India [1,26]. The figures of the present study are higher than the levels in Sadat, Egypt and lower than those of Isfahan, Iran; Tamilnadu, India and Birmingham, UK.…”

Heavy metals' origin, accumulation, and distribution in soil samples have been the focus of much attention by many researchers to monitor soil pollution. The objective of this study is to determine the levels of the heavy metals such as lead (Pb), cadmium (Cd), copper (Cu), and zinc (Zn) in the soil samples collected from different areas residential, industrial and agricultural of Al-Diwaniyah governorate southern Iraq using the effective technique of atomic absorption spectroscopy AAS, so that the degree of pollution could be ascertained. The results show that the mean values of Pb, Cd, Cu and Zn concentrations in soil samples are 31.75, 1.804, 18.51 and 29.82 mg/l, respectively. The results show that the heavy metals concentrations were found to be higher in industrial regions than the other locations. Mean values of Pb and Cd in soils studied were generally higher than the acceptable limits, suggesting some degrees of pollution with heavy metals.

“…The samples were oven dried at 105 °C for 24 h to a constant weight and sieved using a 63 μm sieve. The use of grain sizes of <63 μm, in such analysis has several advantages including (1) heavy metals are mainly linked to silt and clay particles (2) this grain size is like that of suspended matter in water, and (3) it has been used in many studies on heavy metal contamination [ 23 ]. Then the samples were grinded to a fine powder using an agate martor.…”

“…It should be emphasized that only a small pool of free metal or metalloid ions remains dissolved in water, while a large quantity of them are accumulated in the bottom sediments (as a result of adsorption, hydrolysis and co-precipitation processes) (Wardhani et al 2017). Sediments act both as a sink and source of potentially toxic elements in aquatic ecosystems (Saleem et al 2015;Devanesan et al 2017), which may be re-suspended and cause secondary contamination to the water bodies (Wardhani et al 2017). Moreover, these potentially toxic elements may accumulate in the tissues of aquatic organisms and cause various negative effects, associated with limiting of growth, metabolic processes, etc.…”

Study was aimed to assess the potential ecological risk of nine metals (Al, Cd, Cr, Cu, Fe, Mn, Ni, Pb, and Zn) and one metalloid (As) in bottom sediments of the Dzierżno Duże Reservoir located in the key anthropogenic "hot spot" area-Upper Silesian Industrial Region (Poland). Sediments were collected in seven sampling sites, along the main axis of a reservoir. Statistical analysis revealed a significant correlation (p < 0.05) between the potentially toxic elements, which indicated that they plausibly originate from the same source of contamination or have a similar accumulation behavior. Several indices were used to assess ecological risk associated with examined elements, i.e., Enrichment Factor, Geoaccumulation Index, Contamination Factor, Potential Ecological Risk Factor, Probable Effect Concentration, Threshold Effect Concentration, Degree of Contamination and Risk Index. The values of analyzed indices indicate that sediments are highly to extremely highly contaminated, especially by Cd, Pb, Zn, and As, which simultaneously pose the highest ecological risk. The results of Cluster Analysis (CA) and Principal Component Analysis (PCA) indicate that Cd, Cr, Fe, Ni, Pb, Zn, and As in the bottom sediments are most likely of anthropogenic origin, while Mn rather from natural sources. The obtained results confirm the usefulness of different indices in assessing the ecological condition of water bodies and prove that the problem of toxic elements contamination in bottom sediments of the Dzierżno Duże Reservoir poses a serious environmental threat.Environmental Earth Sciences (2019) 78:179 Publisher's Note Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations.
