Pollution maybe from industry (4)

I believe the answer is:

dust

'pollution maybe' is the definition.
(dust is a type of pollution)

'from industry' is the wordplay.
'from' indicates a hidden word.
'DUST' is hidden within 'industry'.

(Other definitions for dust that I've seen before include "Clean - dirt" , "Hopes to turn to this" , "Powdered matter" , "The mortal remains" , "Microscopic particles in the air" .)

I've seen this clue in The Telegraph.
