Novel remediation technology for fines rich garden soil as a nonrenewable natural resource was tested in a pilot scale. Efficient treatment of multimetal; Pb, Zn and Cd contaminated soil was achieved. Soil liquid separation combined with soil rinsing in the same process step was introduced.

Novel washing method of metal contaminated soils was developed. Method is based on recycling chelant EDTA in a pH gradient and recycling of process waters using advanced oxidation methods in a closed process loop.

Different electrode materials: boron doped diamond anode, graphite anode, Fe sacrificial anode were examined in electrochemical and Fenton reaction like advanced oxidation processes for treatment of waste waters generated after soil washing.

We applied multi-level approach to access the quality, toxicity and functioning of Pb, Zn and Cd contaminated / remediated soil from vegetable garden in Meza Valley, Slovenia. Soil washing successfully removed labile forms of Pb, Zn and Cd and thus lowered the human and environmental hazard of remediated soil; however remediation also extracted the trace elements essential for soil biota. Conjointly with lowered water potential soil health was not completely restored.

We studied plant performance on contaminated / remediated soil, and safety of crops produced. Two experimental plots 4×1×0.3 m were filled with remediated and original soil. Selected cultivars were rotated within 16 months. Pb, Zn, Cd and micronutrient plant uptake was measured by AAS and their phytoaccessibility by DTPA method. Plant fitness was assessed by chlorophyll fluorescence and gas exchange measurements and evaluation of root colonization with mycorrhizal fungi. Remediation reduced plant uptake of Pb bellow concentration stipulated by legislation. Measures to reduce plant accumulation of other toxic metals and to revitalize remediated soil are needed.
