I wonder what airline insurance companies make of this issue? I mean workplace exposure to asbestos turned out to be a disaster for the insurance industry once the link was proved. I guess they have two choices - a) sponsor their own research and if there is a problem encourage airlines to eliminate it or b) deny a problem exists, ignore it and hope nobody is able to prove it.
Edit: Looks like the DfT are taking a lead...
