Note superficial pollution (6)

Ross

I believe the answer is:

blight

'pollution' is the definition.
(thesaurus)

'note superficial' is the wordplay.
'note' becomes 'b' (musical note).
'superficial' becomes 'light' (light can mean superficial or trivial).
'b'+'light'='BLIGHT'

(Other definitions for blight that I've seen before include "Setback" , "Shrivelling disease" , "Affliction" , "Withering disease (in plants)" , "Pestilence - state of decay" .)

I've seen this clue in The Globe and Mail.
