Description
Summary:The major changes in isotopic composition of natural waters occur in the atmospheric part of the water cycle and in surface waters which are exposed to the atmosphere. This study demonstrated the utility of the Continuous Flow – Isotope Ratio Mass Spectrometry method for measuring natural variation of the occurring isotopes of hydrogen (2H) and oxygen (18O) in meteoric waters. The variation of δ18O and δ2D values from precipitation fallen in Raureni-Valcea area between May-December 2007 and September 2008-March 2009 were measured together with the δ18O and δ2D values from the Bistrita River. The Local Meteoric Water Line was reported for this area. Also, the variation of δ18O and δ2D values was correlated with the temperature and humidity in the same period.
