Novel reaction of alkaline substitution of toxic metals in EDTA chelate and alkaline precipitation and adsorption of released toxic metals on polysaccharides, coupled to acidic precipitation of EDTA was used to develop a novel, soil-sustainable method for remediation of toxic metals contaminated soils.

The efficiency of remediation for reduction of lead blood levels in children was investigated using 200 soil samples from Meza Valley, Slovenia. Soils were remediated using chelating agent EDTA. Children lead blood levels before and after remediation were determined using IEUBK madel. Data were geostatistically presented.

Acidic and calcareous Pb, Zn and Cd contaminated soils were EDTA-washed. Remediated soil was revitalized by addition of microbially reach unpolluted soil, compost and biochar. The effect of revitalization was assessed by measuring the activites of soil glucosidases, ureases and hydroxylases and by assessing microbial community composition and abundance.

Emissions of EDTA and EDTA complexes with toxic metals after soil washing represent potential environmental problem. Emissions resulting from the use of different EDTA salts were investigated in various soil samples.

Despite efficient remediation soils heavily contaminated with toxic metals remain unsuitable for food production. We investigated the use of heavily contaminated, EDTA-remediated soils in horticulture.
