Human spaceflight habitats rely on environmental control and life support systems to manage cabin air quality, including trace metabolic gases generated by crew members.

The analysis

The claim is specific, empirical, and testable regarding spacecraft life support systems. Papers [7], [8], and [9] explicitly discuss spacecraft cabin air quality control, trace chemical contaminant loads, and air revitalization systems designed to handle metabolic and offgassed loads. There are no refuting papers.
