Lead-free transport gets attention (3)
I believe the answer is:
ear
'attention' is the definition.
(having someone's ear is having their attention)
'lead-free transport' is the wordplay.
'lead-free' means to remove the first letter (the letter which leads the word is removed).
'transport' becomes 'bear' (bear can mean to transport or carry).
'bear' with its first letter taken away is 'EAR'.
'gets' is the link.
(Other definitions for ear that I've seen before include "Part of a cereal plant containing the seeds" , "Appreciation of sounds" , "Place for a plug" , "Organ of hearing" , "Musical ability" .)
