  1. Multi-elemental analysis of jet engine lubricating oils and hydraulic fluids and their implication in aircraft air quality incidents.

    Article - En anglais

    The flight crews of aircraft often report symptoms including dizziness, nausea, disorientation, blurred vision and tingling in legs and arms.

    Many of these incidents have been traced to contamination of cabin air with lubricating oil, as well as hydraulic fluid, constituents.

    Considering that these air contaminants are often subjected to temperatures in excess of 500°C, a large number of different exposures can be expected.

    Although the reported symptoms are most consistent with exposures to volatile organic compounds, carbon monoxide, and the organophosphate constituents in these oils and fluids, the involvement of these agents has not been clearly demonstrated.

    Possible exposure to toxic elements, such as lead, mercury, thallium and others, have not been ruled out.

    In order to assess the potential of exposure to toxic elements a multi-elemental analysis was done on two hydraulic fluids and three lubricating oils which have been implicated in a number of air quality incidents.

    A secondary objective was to establish if the multi-elemental concentrations of the fluids tested are different enough to allow such an analysis to be used as a possible method of identifying the source of exposure that might have been present during aircraft air quality incidents.

    No significant concentrations of toxic elements were identified in any of the oils or hydraulic fluids. (...)
