Sr ISOTOPES AND ROMAGNA WINES: AN OPPORTUNITY FOR BETTER TRADING?
EQA, 2011 La composition isotopique du Sr a été mesurée dans 11 vins de Romagne, parce que la détermination de ce paramètre peut être utile à tracer l’origine des produits pour une meilleure commercialisation. Les 87Sr mesurés se sont avérés homogènes au sein d'une faible amplitude de valeurs (-0.07 et +0.33 o/oo), en accord avec la provenance des raisins d’une ...

Bioavailable soil and rock strontium isotope data from Israel [PDF]
Earth System Science Data, 2020 Strontium isotope ratios (87Sr ∕ 86Sr) of biogenic material such as bones and teeth reflect the local sources of strontium ingested as food and drink during their formation. This has led to the use of strontium isotope ratios as a geochemical tracer in a
