“…The Pb in all three depths of soil revealed higher concentration in the N-E quadrant ( Figure 9A) of the study area, while a small-scale discontinuity pattern of Pb was found with a concentration level of 6 mg kg −1 ( Figure 9B) in the subsoil. The patterns of medium and low concentrations in Figure 9C were observed under the lead emission drain that form slow sinks of Pb in the deep-soil profiles [74].…”

“…Most important in our study is the finding that Pb extractability was below 0.01% of the total Pb content for treatments up to 8000 mg kg −1 in the case of the carbonate and organic-rich soil H1. In this case, retention of lead by soil organic matter can be attributed to the formation of organic complexes [53]. Different authors have observed that high levels of organic matter, mainly found in surface soil layers, are an important sink for lead [28,54].…”

“…The term potentially toxic elements (PTE, Alloway, 1995) is referred to a group of elements, such as As, Ba, Cd, Cr, Ni, Pb, Se, and Zn. This term is more inclusive and appropriate than toxic or heavy metals as it embraces metals, metalloids, nonmetals and other elements in soilplant-animal systems (Coppola et al, 2010). PTE occurs naturally in soils and are influenced by both natural factors (parent materials and pedogenesis) and anthropogenic activities (Zhao et al, 2007).…”

“…Environmental monitoring of PTE is important for controlling their concentrations in the environment, particularly in agricultural soils (Chrzan, 2016). The natural background concentrations of PTE in soils with no or minimal human influences, represent an important level used for establishing threshold values in order to differentiate contaminated from "clean" soils (Coppola et al, 2010). These values can serve as legislative tools for developing guideline values for soil pollution prevention, control and, remediation activities if necessary.…”
