Stable Isotopes

This study addresses the important question of differentiating natural and anthropogenic sulphur in the environment.

International experts explain how stable isotopes of sulphur and oxygen have been used to study the origin and transformations of sulphur in ecosystems. The topic is treated in logical sequence beginning with an overview of the basic principles of sulphur and oxygen isotope research and including descriptions of how investigators have successfully applied, or plan to apply, stable isotope techniques to study sulphur in a variety of ecological systems throughout the world.

The book is the outcome of a workshop of the SulphurUnit of the United Nations Environmental Program.
