Short summary
The oxidative potential (OP) of air pollution particles might be a metric explaining particle toxicity. This study quantifies the OP of fresh and aged car and wood burning emission particles and explores how the OP changes over time, using novel high-temporal-resolution instruments. We show that emissions from wood burning are more toxic than car exhaust per unit particle mass, especially as they age in the atmosphere. We also calculate emission factors for the OP, which could help to improve air pollution policies.
