For a defined process, a change in 18O/16O scales with the corresponding change in 17O/16O, or the fractionation factors 18α and 17α have a relationship of θ = ln17α/ln18α, in which the triple oxygen isotope exponent θ is relatively fixed but does vary with reaction path, …
WebThese findings reveal how sensitive stable isotopes are to topography, runoff production, and changes in land use, and they have implications for possible water and environmental problems. These insights served as the foundation for recommendations for the management of the water environment in both urban and rural settings.
