Tricresyl Phosphate Measurement Methods Used to Identify Flight Crew and Passenger Exposure

Measurement TCP isomers in aircraft environments indicates jet engine oil exposure from bleed air. The neurotoxic, and other, effects associated with these agents make it imperative that exposure measurements are done accurately. Wipe samples are an indicator of the presence of, rather than exposure to, agents. Air sampling is an indicator of inhalation exposure but varies between methods. The VN air sampler was ideal to capture rare bleed air events. Carbon monoxide, formaldehyde, and ultrafine particulates need monitoring. Axonal transport of ultrafine particles by the olfactory nerve was postulated as one possible route of exposure of the CNS to TCP.This paper is part of: "2017 International Aircraft Cabin Air Conference : Conference Proceedings".
