Modelling oxidative potential of atmospheric particle: A 2-year study over France.

The oxidative potential (OP) of particulate matter (PM) has emerged as a promising indicator of the adverse effects of PM on human health. In particular, OP is an indicator for oxidative stress in biological media through formation of reactive oxygen species. To provide a mapping of the spatial and temporal OP variability over France, we have developed a strategy to simulate the volume-normalized oxidative potential (OP) in the state-of-the-art CHIMERE air quality model over the metropolitan French territory for the years 2013 and 2014.
