Description

The 1998 Federal Soil Protection Act emphasizes the importance of precaution values as a measure for the preservation of soil quality. This requires regionally representative backround levels in order to define guiding criteria for the soil protection. The aim of this work is to improve the rather insufficient data base on the distribution of background levels of polycyclic aromatic hydrocarbons (PAH) in Central European soils. This is done by spatial investigations using standardized methods.In three nature reserves in Germany, Poland and the Czech Republic, the distribution of polycyclic aromatic hydrocarbons (12 EPA-PAH) in topsoils of different use and in the litter layers was examined to develop a basis for backround values. For each of the three survey-areas, a scaled hexagon grid was set up to define locations for taking samples every 1,5 kilometres. As a result, 62 samples at 38 locations were taken in the Spreewald Biosphere Reserve in Germany. These were divided in soil, litter and grass samples. In the Kampinoski National Park in Poland as well as in the Soutok Nature Reserve in the Czech Republic, 59 samples were taken at 35 locations respectively.The results show that three factors influence the distribution of the PAH-levels in the areas: land use, flooding and air pollution are the determining factors. As far as land use is concerned, PAH-contents increase of the from agricultural land to grassland to forest and to litter. If one further distinguishes between different forest types, an increase of PAH-contents from pine forest soils to soils of oaks-beech to alderfen forests can be observed. PAH increases here correspond to increases in organic substance. In contrast to this PAH-contents in the litter layers were 30 percent higher than PAH-contents in the litter layers of deciduous forests.Flooding influences parts of the Spreewald Biosphere Reserve and the Soutok Nature Reserve. At inundated locations an additional input of particlebound PAH
