Short summary
In this study, we develop and apply a kinetic model that estimates oxidative potential (OP) based on particulate matter (PM) composition. The model consolidates a large set of laboratory data from different OP assays in the presence of organic molecules, metals, and quinones. We applied the model to field data of PM composition and OP and found good agreement across three sites. The model analysis indicates that OP is mainly driven by organic molecules and copper.
In this study, we develop and apply a kinetic model that estimates oxidative potential (OP)...
