摘要: Strontium isotope ratios and Ca2+, Na+, K+, Mg2+, Cl−, , Sr2+ concentrations were measured in rainwater samples collected four stations France (Brest, Dax, Orleans Clermont-Ferrand) over a period of 1 year. Each sample represented monthly series rain events. The chemical composition the 87Sr/86Sr varied considerably. Using Na as an indicator marine origin, proportion crustal elements was estimated from elemental ratios. isotopes used to characterize different sources using data literature. Such include sea salts, (carbonates, silicates volcanic rocks) anthropogenic (fertilizers, automobile exhausts, incinerators urban heating).
