Relative binding strength for heavy metals up to 1m tread depth 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 bond strength for the respective heavy metal up to 1 m below GOF for the surface soil shapes involved. For this purpose, all horizons including the support horizons up to 1m under GOF are used. For each horizon, the metal-specific pH-dependent binding strength is determined and surcharges are added for corresponding humus and clay contents. The parameters thus determined are weighted, averaged and ordinally scaled in steps 0 to 5 for the horizons up to 1 m below GOK, with the maximum value 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 7.2).
