Strontium isotopic signatures of natural mineral waters, the reference to a simple geological map and its potential for authentication of food

摘要: Abstract This paper presents the investigation of strontium isotope ratios about 650 different European natural mineral waters as part food traceability project “TRACE” funded by EU. Analysed 87Sr/86Sr values in range from 0.7035 to 0.7777, which indicates an influence a great diversity rocks young mantle derived basaltic very old silicic continental crust. The results large scale are used elaborate novel spatial prediction for combining measured data with GIS based geological map Europe. resulting can be predict isotopic composition groundwater and thus bio-available strontium, is available uptake plants subsequently transferred into chain. We also show, example, that honey wheat specific sample regions within TRACE correlates well water predicted our map. proof principle shown highly relevant geographical authentication it allows assessment origin products without immediate need geographically authenticated materials may not always available. Our approach provides cost effective first instance screening tool.
