Isotope ratio mass spectrometry application for environmental investigations

Abstract

Stable isotope ratio mass spectrometry (IRMS) is a useful technique with a broad range of applications. Stable isotopes are important indicators of environmental changes (including climate), and can be used to explain the functioning of biogeochemical cycles. Examples of IRMS aplications in the fields of environmental science, paleoecology/climatology, and analysis of atmospheric pollution are presented in this paper. These studies were carried out using an isotope mass spectrometry complex (Tomsk Regional Сore Facilities of Tomsk Scientific Center of Siberian Branch of the Russian Academy of Sciences (SB RAS)) at the Institute of Monitoring of Climatic and Ecological Systems of SB RAS.
