“…From Table 1, it is clear that the acid mine drainage contaminated soil is not contaminated with Zn, Cd, Pb and Cu. This finding was also supported by other authors [33][34][35][36]. Significant amount of metal is not bioavailable in contaminated soil due to the presence of high organic matter, which is known to adsorb considerable amounts of toxic metals ions, by an ion exchange mechanism or by specific adsorption [37].…”

“…Therefore, the acid-soluble fraction may overestimate the Cd phytoavailability in soil, since acetic acid solution extracted more Cd from soil. It should be noted that the Ca(NO 3 ) 2 -extractable fraction generally includes both water-soluble Cd and partially adsorbed onto inorganic/organic soil components through electrostatic interaction . Therefore, it is still a challenge to determine which of the fractions (water-soluble or Ca(NO 3 ) 2 -extractable Cd) is the main source of Cd in rice plants.…”

This study aims to understand the influence of salinity and labile organic matter removal on the fate and behavior of metals in coastal technosols. Two technosol cores were collected near the Lebanese shore. The cores were sectioned into layers; each layer was characterized for pH, salinity, electric conductivity, labile and total organic matter, grain size, and total and oxalate-extractable metals. Consequently, two saline solutions were used in desorption experiments to understand the role of ionic strength and labile organic matter on metal release. The results showed that the technosol layers were highly heterogeneous; most layers were enriched with Fe, Zn, Pb and Cu. The mineralogical investigations showed that the metals, notably Fe, were not present as crystalline minerals, rather big percentages of the metals were found in amorphous or poorly crystalline phases. Desorption experiment showed that Mg release was dependent on salinity and organic matter in both technosols, while Pb release was dependent on both factors only in one. Additionally, Zn and Cu were associated to organic matter, and their release was conditioned by the removal of labile organic matter; iron was primarily found as amorphous or poorly crystalline phases, and salinity had a major role in its release. The role of ionic strength and labile organic matter removal on the behavior of metals in technosols was demonstrated. Finally, understanding metal dynamics between the solid and liquid compartments in technosols, especially where salt deposition occurs, is important to reduce unwanted metal leaching to groundwater or seawater and transfer to biota.
