PAHs - Background values of low-influenced soils in Schleswig-Holstein

The data set "PAK - Background values of low-influenced soils in Schleswig-Holstein" contains the 90th percentile values of 13 evaluation classes for the substance group PAK16 as a nationwide 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). In the map, regional arsenic contents that are still to be assessed as typical are shown as background values. As class limits for the color gradation, the 50s, 75s, 90s and 95 percentile values of the total data stock without forest conditions are used. Thus, compared to a distribution valid for the whole of Schleswig-Holstein over all uses, area-related units can be well represented in their tendency.
