Stable isotope analysis has emerged as a pivotal tool in elucidating the pathways and interactions of water within both natural and managed landscapes. By tracing the distinctive signatures of ...

Stable isotopes are safe, non-radioactive forms of common elements such as carbon, nitrogen and hydrogen that occur naturally in small amounts in the foods and water we consume every day. Because they ...

The discovery of stable ''isotopes" began with J. J. Thomson's identification of neon-22 in 1912 (Bievre et al., 1984). More than 90 naturally occurring elements have been identified on the earth; ...

The IAEA offers a variety of training courses in the fundamentals of isotope hydrology and isotopic analyses of stable isotopes, tritium, and noble gases. This course provides an overview of advances ...

After chemical preparation and purification, very small samples from animal teeth are loaded into the magazine of an isotope ratio mass spectrometer to obtain oxygen stable isotope ratios, which yield ...

Over 100 species of wild migratory birds, particularly ducks, swans, geese and various wading birds, harbour avian influenza (AI) viruses. Infections are transmitted amongst the wild birds by shedding ...

Water drawn from a living Equisetum plant, called horsetail, has registered the most extreme oxygen isotope signature ever ...
