The potential exposure of aircraft maintenance personnel, flight crews, and passengers to pollutant emissions from jet engines—and more specifically to volatile, semi-volatile, and non-volatile organic compounds—has been a concern for the civil and military aviation industries for several years. In this context, investigations have been conducted in the United States by the EPA (Environmental Protection Agency), in collaboration with the U.S. Air Force, to assess the health risk associated with the inhalation of polycyclic aromatic hydrocarbons (PAHs), known for their carcinogenic potential. This article is particularly interesting from a metrological standpoint, highlighting the benefits and limitations of real-time PAS-type analyzers. The concentration levels recorded during this study, across various measurements, are especially relevant from an occupational health perspective. The document also provides some semi-quantitative data on the exposure levels of airplane passengers, but it does not offer relevant information for assessing the exposure of populations living near airports.
