Divergence of stable isotopes in tap water across China
Stable isotopes in water (e.g., δ2H and δ18O) are important indicators of hydrological and ecological patterns and processes. Tap water can reflect integrated features of regional hydrological processes and human activities. China is a large country with significant meteorological and geographical variations. This report presents the first national-scale survey of Stable Isotopes in Tap Water (...

متن کاملStable isotopes in tree rings
Stable isotopes in tree rings could provide palaeoclimate reconstructions with perfect annual resolution and statistically defined confidence limits. Recent advances make the approach viable for non-specialist laboratories. The relevant literature is, however, spread across several disciplines, with common problems approached in different ways. Here we provide the first overview of isotope dend...
متن کاملStable Isotopes in Ecosystem Studies
The use of stable isotopes to solve biogeochemical problems in ecosystem analysis is increasing rapidly because stable isotope data can contribute both source-sink (tracer) and process information: The elements C, N, S, H, and all have more than one isotope, and isotopic compositions of natural materials can be measured with great precision with a mass spectrometer. Isotopic compositions change...
متن کاملStable isotopes in carotenoid biochemistry
The use of stable isotopes in studies of carotenoid biosynthesis is reviewed, beginning with early work with l8 which defined the origin of oxygen in a range of xanthophylls. A series of experiments from our own laboratory is then described, in which 2H and 13C have been used to investigate the stereochemistry of cyclization to form C40 and C50 and i-ring carotenoids. Novel procedures involving...
