Bit of air pollution (3)

Ross

I believe the answer is:

ash

'bit of air pollution' is the definition.
(I've seen this in another clue)

This is all the clue.

(Other definitions for ash that I've seen before include "Burnt remains; tree" , "-- Wednesday" , "Timber tree" , "Tree with winged seeds" , "Silvery grey" .)

I've seen this clue in The New York Times.
