Relative binding strength for heavy metals for the groundwater-free soil area Brandenburg

Description

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. This map shows the relative binding strength for the respective heavy metal in the groundwater-free soil space or up to the upper limit of a Go horizon or up to 2 m under GOF for the surface soil forms involved. For this purpose, topsoil (including support horizons up to 3 dm under GOF) and subsoil are treated separately. For the topsoil, the characteristic value is determined as above up to the step of the ordinal scaling. For the characteristic value of the following depth range up to 2 m below GOF or up to the upper limit of the Go horizon per soil form, the horizon with the highest pH-dependent binding strength is considered if this is > 3 dm thick. Otherwise, from the directly hanging or lying horizon, the one weighted according to its thickness is used to average the characteristic value, which has the higher pH-dependent binding strength from these two horizons. Additions for corresponding humus and clay contents are then added. The so determined characteristic values for top and bottom are added and ordinally scaled in stages 0 to 5, whereby the maximum value is limited to 5. With different results for the soil forms of a legend unit, the area-dominant and the subdominant ordinally scaled classified characteristic values were given (see Hennings 2000, VKR 7.3).
