Speciation of Zn, Cu, and Pb in the soil depending on soil

Zn, Cu, and Pb speciation was performed according to the modified methodology of Tessier et al. (Anal Chem 51:844851, 1979) in two different (sandy and clay) soils with background HM amounts and in soil samples amended with aerobically digested SSC to find out the predominant species of the investigated HM and to predict their potential availability.

Original Research Speciation of Cu, Zn, and Pb in Soil

The concentrations of Cu, Zn, and Pb in soil solutions were measured after different incubation times within 30 days. Speciation of metals in soil solution was determined via modeling with Visual MinteQ. Soil amendment with all organic materials led to a temporary increase of Cu concentrations in soil solutions.
