“…Several studies have estimated the total metal contents in polluted and unpolluted soils (Vega et al 2004;Covelo et al 2007;Kierczak et al 2008;Maas et al 2010;Nemati et al 2011;Wali et al 2013, Mohamed et al 2015, Elnazer et al 2015Salman et al 2016;Salman et al 2018;Said et al 2019). However, the total contents of trace metals cannot give enough information about their various forms, mobility, bioavailability, or potential risks to the environment (Davutluoglu et al 2011;Nemati et al 2011).…”

Background: Heavy metals have dangerous effect on the biota. So, this work aimed to determine the mobility and bioavailability of these metals through the application of pollution indices and geochemical fractionation technique. Thirty-one topsoil samples (20 cm) were collected from the area between Abu Qurqas and Dyer Mawas, El Minya Governorate, and subjected to chemical analysis. Results: The results revealed that Cd and As are mainly associated with carbonate fraction while Cr, Pb, Ni, and Cu are more present in the residual fraction. The relative amounts of easily dissolved phase of heavy metals in the soils are in the order of As > Cd > Cr > Pb > Ni > Cu. Conclusion: The results revealed that As, Cd, and Cr have high mobility and risks more than Pb, Ni, and Cu metals in the studied soils. As, Cd, and Cr were the heavy metals that caused pollutants in the soils of the studied area.

“…This sandy nature of soil may be due to the depletion of humus from the soil [29]. The content of heavy metals in soil is inversely proportional with the soil particle sizes and accumulates in the clay and silt fraction of soil [9]. This can be supported by the positive correlation between metals and both silt and clay (Fig.…”

“…Thus, the alkaline environment will lead to the accumulation of heavy metals [27]. In addition to the pH of the soil, OM is the primary contributor to retain heavy metals in the soil through the formation of complexes or as exchangeable forms [9]. Based on the USDA [28] classification of soil texture, the soil was mostly loam (Fig.…”

“…The sequential extraction steps, since proposed by Tessier [8], have been applied widely to study chemical speciation of metals. Several modified procedures were proposed elsewhere to determine the extractable heavy metals load in soils and sediments [9][10][11][12]. The application of sequential extraction procedures led to the development of an important index for assessing metal mobility and bioavailability risks [11][12][13].…”

Toxic elements behavior in Egyptian soil need more studies for the enhancement of soil quality and human health protection. The current study focuses on the mobility assessment of chemical species of As, Pb, Cr, Ni, Cu and Co in soils due to anthropogenic emission using sequential extraction (SE) and risk assessment code (RAC). Generally, the studied soils are alkaline calcareous loam soil. It has a low organic matter (OM) that ranges from 1 to 3.8% and is enriched with As, Pb, Cr, Ni, Cu and Co, which preferentially accumulate in soil clay and silt fraction. SE revealed that the non-residual (bioaccessible) fraction contains about (70.7%) As, (65.2%) Co, (58.8%) Cr, (28.4%) Cu, (6.8%) Ni and (64.5%) Pb, indicates the risk of pollution with As, Co, Cr, and Pb. RAC values indicated a high risk of soil pollution with As, medium risk of Co and Pb, low risk of Cu and Ni, and no risk of Cr. The results pointed out the geogenic source of Cr, mixed source of Co, Cu, and Ni and the anthropogenic source of As and Pb. The spatial distribution analyses of these metals indicated the role of urbanization, traffic, and industry on the releasing of toxic metals into the environment.

“…The natural content of metals in parent material can be considered as the geochemical background in soil [8]. The main anthropogenic sources of heavy metals are industrialization, urbanization, vehicle exhaust and agricultural activities [11]. The resulted metals from anthropogenic activities are more mobile and harmful for the environment than those resulted from the natural process.…”

A SSIUT District represents an important part of central Nile Valley. It is a complex district containing many big industries, urbanization and agricultural activities. These activities can lead to the pollution of agricultural soil with toxic heavy metals. The aim of this work is the assessment of potential risks of these metals in soils using pollution indices; Enrichment Factor (EF), Index of Geoaccumulation (I geo ), Contamination Factor (CF), Ecological Risk Factor (E r ), Degree of Contamination (C d ), Pollution Load Index (PLI) and Potential Ecological Risk Index (PERI). The present study calculated the mentioned indices for eight heavy metals; As, Cd, Co, Cr, Cu, Ni, Pb, and Zn.Pollution indices calculations revealed that the investigated area can considered generally moderately polluted with the studied heavy metals. The emission of heavy metals from the factories as well as agricultural practices, urban runoff and sewage stations in the zone may be the source of that pollution. Consequently, control methods must be functional to the area adjacent to the factories to diminish the pollution. Finally, the studied cultivated soils showed low pollution than other cultivated soils in Australia,
