Toxicological Assessment of the International Space Station Atmosphere from Mission 5A to 8AThere are many sources of air pollution that can threaten air quality during space missions. The International Space Station (ISS) is an extremely complex platform that depends on a multi-tiered strategy to control the risk of excessive air pollution. During the seven missions surveyed by th is report, the ISS atmosphere was in a safe, steady-state condition; however, there were minor loads added as new modules were attached. There was a series of leaks of octafluoropropane, which is not directly toxic to humans, but did cause changes in air purification operations that disrupted the steady state condition . In addition, off-nominal regeneration of metal oxide canisters used during extravehicular activity caused a serious pollution incident.
