Scientific program 01
Using distinctive isotope signatures and chemical measurements to investigate ozone-mediated oxidation, reactive nitrogen, particulate matter, and pollution-related processes.
Program overview
Ozone carries an unusual oxygen-isotope composition. When ozone participates in oxygen-transfer chemistry, part of that signature can be inherited by reaction products, providing a tracer of oxidation pathways.
The laboratory applies this concept to particulate nitrate and related pollution chemistry. Current directions also connect particulate composition and chemical reactivity with environmental epidemiology, with the goal of moving beyond particle mass alone toward mechanistic exposure indicators.
