Finding F-1263
“The O3 production found at a UV path length of 0 m (17 ± 13 μg h−1) confirms that no significant amount of O3 is produced from electrical discharge, as opposed to what has been observed in previous studies.”
Structure
- Factor
- Ozone (O₃)
- Setting
- office, DK
- Study design
- measurement study in office spaces in Denmark: germicidal ultraviolet lamps with a peak emission at 222 nanometres were run in the rooms while ozone, ultrafine particles and volatile organic compounds were measured continuously before, during and after operation, under unoccupied conditions and with one and with two people present, with the ozone production rate also measured against the ultraviolet path length (class 3)
- Effect
- emission-rate 17
- Caveat
- the sentence prints the spread as a plus-minus value without naming it
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.
