When it comes to the worst air in the nation, L.A.'s still at the top of the list according to the American Lung Association's latest "State of the Air" report.

When it comes to ozone pollution, we're still No. 1. But Los Angeles is behind cities like Bakersfield and Fresno as far as particle pollution is concerned.

There's been an increase in air quality since mass stay-at-home orders started, though the reasons behind that are complicated and likely not long lasting.
