Airliner cabin air quality.

Airliner cabin air quality has attracted a lot of attention in the last two decades and has generated much controversy. This article reviews the situation to date only as it pertains to cabin air quality during normal aircraft operation. First discussed are the basic assumptions from the early days of commercial aviation. Second, different factors involved in cabin air quality are reviewed in some detail. Evidence from the current literature is employed to demonstrate that airliner cabin air quality is adequate and does not compromise aircrew health. However, the author does recognize that further studies are required for additional clarification of the issue.
