In the valley it has been nearly continuously elevated AQI since the lightning strikes in late August. There were a few weeks without. But these are particles --- not gas, so your lungs don't expel it once the particles impact and embed in your tissues. The body doesn't really have a way to clean that out that I'm aware of (I'd like to learn that I'm wrong). As an endurance athlete, I move a lot of air, and I want my lungs to be in good shape.
