Darstellung der Methodik zur beprobungslosen Ausgliederung von Verdachtsflächen großräumiger Bodenkontaminationen am Beispiel des Landkreises "Mansfelder Land"

Abstract

Wide areas of the German Federal of State Saxony-Anhalt are affected by soil contamination detrimental to industrial and agricultural use as well as to the quality of nature and landscape. The sources of contamination are industrial facilities and waste sites as well as traffic, dumps, and a diversity of other sources of hazardous substances. Chemicals used in agriculture contributed heavily to soil pollution. The highest environmental risks are caused by toxic metals, PAH, pesticides, and nitrates. Though there has been collected an immense quantity of data concerning soil contamination for Saxony-Anhalt, data management was poor up to now, and reviews were not available. The system KatBo was created to remedy this deficiency of data management. KatBo aims at marking out sites of health and environmental risks, initially applied without sampling and analytical investigations. At modest expenses this principle delivers the overall view on soil contamination, in many cases together with discernible reference to sources and pathways of hazardous substances. These features are helpful on many occasions of municipal, industrial and environmental planning concerned by state and quality of soil. KatBo aims at soil monitoring of industrial as well as natural pollutants. All available data are filed to an appropriate flexible register designed for updating and upgrading to include future data, results of investigation and soil protection measurements. Important tools of the system include consideration of possible paths of hazards to targets and of likelihood of no risk areas.
