δ18O ISOTOPE MAP-GENERATION OF EUROPEANMINERAL WATERS, APPLICATIONS AND LIMITS

摘要

There is an increasing demand for independent analytical methods which cancontrol the geographical origin of food. The EU project TRACE was started with theaim to develop a general understanding of the relation between the geo-bio-climaticenvironment and the isotope and elemental signature in food commodities. Besidemineral water the agricultural products wheat, honey, olive oil and lamb meat areinvestigated. As one part of the study a detailed δ18O map for groundwater will begenerated by the isotope results of 600 samples of European mineral waters. Theseisotope groundwater maps provide a multitude of applications not only for authenticityof food, but for groundwater recharge and climate studies, criminal forensics as well asarchaeology.
