Our important soil remediation study was published in Geoderma – a great accomplishment by our postdoc Zuzana Vaňková! This work aimed to investigate the stabilizing potential of two immobilizing agents (amorphous Mn oxide – AMO, and AMO-biochar composite – AMOchar) toward As, Cd, Pb, and Zn in two contaminated soils at two different soil moisture regimes (unsaturated and saturated conditions). At the same time, changes in saturated hydraulic conductivity (Ks), soil swelling, and saturated water content were evaluated. Under the saturated condition, the contents of As, Cd, Pb and Zn in soil solution were elevated compared to the unsaturated condition. The study demonstrates the fundamental role of soil moisture content in the stabilizing agents’ performance and highlights the need for future interdisciplinary studies aiming at physical/geochemical/biological aspects of soil systems together.
