You're right, by reducing airflow they can concentrate particulates close to the emitting source and raise levels. Buildings do the same and they don't trap particulates. But even when sited at distance from a pollution source, they act as effective filters and reduce pollution to the leeside of the canopy. Basically we need more trees properly chosen and sited, and more evergreen species than we currently use.

 

Keith Sacre was complaining that the average landscape architects palette of trees consisted of around a dozen species. There's (almost) always something suitable for any given situation. Did I mention that we need more trees?

I think that they change the chemical formulae into less harmful stuff, so less of an issue when they are burnt. Tree are good  I've an article somewhere about using trees/tree pits for surface water runoff in I think Manhatten. The run-off is/was so polluted that it was affecting the river where it ended up. The solution was to run it through 'tanks' with trees and shrubs growing which cleaned it before it flowed onward into the Hudson. All kinds of shite like oil, brake dust and other stuff from vehicles.
