Badania izotopowe d18O, dD oraz d37Cl w wybranych wodach mineralnych Podkarpacia

Abstract

Isotopic investigation of d18O, dD and d37Cl of selected mineral waters in the Subcarpathian area.A b s t r a c t. The paper presents new results of stable isotope ratios (18O/16O, 2H/1H and 37Cl/35Cl) in a few representative mineral waters of the Subcarpathian area. The observed temporal variability of 18O/16O and 2H/1H in waters has thrown a new light onto the origin of these waters. Analysis of 37Cl/35Cl in chlorine ion is indicative of its origin, at least it was possible to exclude a contamination by chloro-organic compounds. The possibility of tracing of migration of this pollution type by simultaneous analysis of chlorine and carbon isotopes is discussed. The results are discussed on the background of geological structures of the aquifers and theirhydrogeological conditions.
