Title : Known Harmful Effects of Constituents of Jet Oil Smoke
Abstract : The construction of cabin pressurization systems of certain commercial aircraft allows pyrolyzed jet oil to leak into the cabin air, often producing visible smoke. The principal toxic constituents of this smoke are tricresyl phosphate, carbon monoxide, and N-phenyl-L-naphthylamine. Long-term neurological effects alleged by airline workers could be due to tricresyl phosphate and/or carbon monoxide exposure.
