Lead and Cadmium in Soils 1991
Maps 01.03.1 and 01.03.2 were prepared by evaluating about 2,900 measuring points of the measuring programs. The measuring programs were initiated to collect comprehensive data regarding heavy metal contamination of specific area uses and to characterize the contamination of larger portions of the city and its bordering areas.
Analyses were not taken into consideration which were made at individual locations for old contaminated sites in the course of initial evaluations and preparations for restoration commissioned by the Berlin Department of Urban Development and Environmental Protection or by borough environmental agencies. Comprehensive heavy metal measurements were regularly conducted in this context, so the maps presented here depict only part of the known soil pollution.
The map shows measurement data next to each other which were collected at different times at areas of varying uses in Berlin and its bordering lands (see Table 1). A classification of the underlying studies, test times and methodology is not possible on the map. The measurements are excerpts from the Heavy Metal Data Base maintained by Department IIIA5 of the Berlin Department of Urban Development and Environmental Protection. Complete information regarding depicted measurement points can be accessed from this Data Base.
