Relative binding strength for heavy metals Brandenburg

This map is based on the legend units of the soil overview map with corresponding assignment of parameterized surface soil shapes. These represent a soil-forming society per unit of legend. Parameters were applied to the individual (surface) soil forms, including those for calculating the binding strength for heavy metals (see Hennings 2000, Chapter 2), which were determined by field and laboratory tests. For the same horizon-substrate combinations, the corresponding parameters (soil type, humus content, pH value) were statistically derived (usually the median value).
The sequence of horizon-substrate combinations in the surface soil forms with their parameters (soil type, humus content, pH value, upper limit of the Go horizon) formed the basis for the calculation of the relative binding strength to heavy metals (see Hennings 2000, linking rule 7.1 to 7.3). The following topic maps show the metal-specific relative binding strength for different depth ranges for the heavy metals Fe(III), Hg, Pb, Cr(III), Cu, Al, Zn, Co, Ni, Cd and Mn.
Relative binding strength for a) heavy metals in the upper soil Brandenburg, b) heavy metals up to 1m profile depth Brandenburg and c) heavy metals for the groundwater-free soil area Brandenburg
