Description: Das Projekt "Optimization of Soil Sampling for Surveying Heavy Metal Contamination" wird vom Umweltbundesamt gefördert und von Eidgenössische Technische Hochschule Zürich (ETH), Institut für Terrestrische Ökologie, Arbeitsgruppe Bodenschutz durchgeführt. Assessment of the current status of soil fertility is a task which federal and cantonal government agencies have been confronted by law since 1987. After preliminary investigations have risen concern about the extent and degree of soil quality, surveys and monitoring programs are urgent in many regions of Switzerland. Due to the high variability of soil properties on small scales and to the high costs of soil sampling and analysis, optimization of sampling schemes is an important issue. The objective of this pilot study is to assess the variability of different site types and to evaluate the benefits of two-stage sampling and analysis of mixed soil samples. The study also serves to design a larger follow-up project in which geostatistical properties of heavy metal distribution in soils on a regional scale shall be investigated.
