Bare in mind, its not just exposure to cabin air, its also through skin contacts for ground engineers. I have worked in aviation since 1970, mostly mucking about with turbines. Made a lot of contact with MobilJetII, Shell Aero500 and Exxon 2380. Eventually health and safety got on the scene and I started to wear protection, gloves and barrier creams. Guess what? retired now I suffer from a neurological disease affecting my feet, legs and awful headaches. Although diagnosed they wont make the connections to my aviation background.
