摘要

The isotopic composition, for example, C-14/C-12, C-13/C-12, H-2/H-1, N-15/N-14 and O-18/O-16, of the elements of matter is heterogeneous. It is ruled by physical, chemical and biological mechanisms. Isotopes can be employed to follow the fate of mineral and organic compounds during biogeochemical transformations. The determination of the isotopic composition of organic substances occurring at trace level in very complex mixtures such as sediments, soils and blood, has been made possible during the last 20 years due to the rapid development of molecular level isotopic techniques. After a brief glance at pioneering studies revealing isotopic breakthroughs at the molecular and intramolecular levels, this paper reviews selected applications of compound-specific isotope analysis in various scientific fields.
