Background values ​​of soils in Schleswig-Holstein with little material influence

The data set "Background values ​​for soils in Schleswig-Holstein with little material influence" contains the 90th percentile values ​​of 13 evaluation classes for 12 substances or groups of substances as a state-wide map representation. The evaluation classes are formed from information on the uses of arable land, grassland and forest as well as on the soil (soil type/peat, soil types). Data is included for the following substances or groups of substances: arsenic, lead, cadmium, chromium, copper, nickel, mercury, zinc, PAH16, benzo(a)pyrene, polychlorinated biphenyls (PCB6), dioxins and furans. In the maps, substance contents that are still to be estimated as typical are shown regionally as background values. The 50th, 75th, 90th and 95th percentile values ​​of the entire database without forest restrictions are used as class limits for the color gradation. In this way, the trend of area-related units can be shown well compared to a distribution that is valid for the whole of Schleswig-Holstein across all uses.
