Finding F-1307

“When previously worn t‐shirts were in the chamber, more than 96% of the ozone removal was attributable to the combination of surface reactions and ventilation (about 40% at AER = 1 h−1 and 70% at AER = 3 h−1 ), while gas‐phase reactions accounted for less than 4% of the ozone removal.”

Structure

Factor: Ozone (O₃)
Method: Emission test chamber method
Setting: test chamber, SE
Study design: climate chamber study of ozone reacting with human skin oil: previously worn t-shirts stood in for occupants while the chamber was ventilated at two air exchange rates and supplied with two initial ozone mixing ratios, with the oxygenated products measured by chemical ionization mass spectrometry and the formation and removal quantified through mass balance equations, including an intermittent ventilation case (class 4)
Effect: other 96
Caveat: gas-phase reactions account for less than 4 per cent of the removal; worn t-shirts stand in for occupants, so the shares belong to a chamber, not to a room with people in it
