Organophosphate and Amine Contamination of Cockpit Air in the Hawk, F-111 and C-130 Aircraft
Abstract
A survey of cockpit air contamination by organophosphates and amines in the Hawk, F-111 and Hercules C-130 aircraft was undertaken. The air contamination occurred via the engine bleed air supply. The source of tricresyl phosphates, pheny-alpha-naphthylamine and diotyldiphenylamine was jet engine oil while hydraulic fluids are suspected of contributing to the presence of trialkyl phosphates. The concentrations of all contaminants measured were generally very low. Tricresyl phosphate concentrations were below 4 mug/m3 with two exceptions (21.7, 49 mug/m3, Hawk) compared to the maximum permissible concentrations (100 mug/m3). Ground engine starts, at high power, gave rise to the highest concentrations. Phenyl-alpha-naphthylamine and dioctyldiphenylamine concentrations were also very low (<0.06 mug/m3) in the Hercules C-130 and the absence of exposure limits for the two compounds reflects on their apparent low toxicity.
