Finding F-1300
“The relative contribution of gas-phase reactions to the total ozone removal was estimated to be between 5% to 30% for pine wood depending on relative humidity and on the incoming ozone concentration and 2% for polystyrene tiles.”
Structure
- Factor
- Ozone (O₃)
- Method
- Emission test chamber method
- Setting
- test chamber, FR
- Study design
- doctoral thesis at Universite Paris-Diderot on ozone and indoor air quality: fourteen new and unused building and decoration products were exposed to ozone in a test chamber at controlled temperature and relative humidity over 48-hour experiments, with the ozone removal, the deposition velocity and the share of gas-phase reactions measured for each product (class 4)
- Effect
- other 30
- Caveat
- the share depends on the relative humidity and on the incoming ozone concentration, so it is a range, not one value
A Finding records what one published document states, verbatim and with its page. It is not a conclusion of Coridum; see the Claims that build on it.
