Chromium — Background values of materially low-influenced soils of Schleswig-Holstein

The data set “Chrome — Background values of materially low-influenced soils of Schleswig-Holstein” contains the 90th percentile values of 13 evaluation classes for chromium as a national map representation. The evaluation classes are formed from information on the uses of arable, grassland and forest as well as soil (type of soil/trees, soil types). The map shows regionally as typical arsenic content as background values. The 50s, 75s, 90s and 95 percentile values of the total data stock are used as class limits for the colour gradation. In contrast to a distribution valid for the whole Schleswig-Holstein over all uses, area-related units can be well represented in their tendency.
