Stable Isotope Mixing Models Publications
Stable isotope analysis can be used in ecological studies to trace chemical movement through the environment. A common application is to use the isotopic composition of a mixture to determine the proportions of various sources in the mixture, using mathematical mixing models. The publications listed below describe three mixing models developed by EPA, and the application of mixing models to environmental problems. For further details and links to downloadable models, see the Stable Isotope Mixing Models for Estimating Source Proportions page.
