Finding F-1253

“Refraining from changing clothes for 3 days increased the total emissions of key products by ∼25%, while refraining from showering for 3 days showed minimal effect, likely because skin oil on body surfaces rapidly re-equilibrates.”

Structure

Factor: Volatile organic compounds (VOCs)
Method: Emission test chamber method
Population: three adult volunteers
Setting: test chamber, CN
Study design: single-person chamber experiments with three volunteers at Tsinghua University: emission fluxes of the products of skin oil ozonolysis measured with a proton transfer reaction mass spectrometer with and without ozone injection, while air temperature, relative humidity, bathing frequency, clothing soiling and clothing coverage were varied one at a time (class 3)
Effect: difference 25
Caveat: the sentence prints the increase as approximate
