Finding F-1306
“The results of the present research, along with the results of the study conducted by Weschler and Shields (18) show that the potential exists for the accumulation of PM2.5 in excess of 20 μg/m3 in indoor air as a result of using terpene-based products in the presence of elevated outdoor-generated O3 concentrations.”
Structure
- Factor
- Particulate matter (PM₂.₅ and PM₁₀)
- Setting
- test chamber, US
- Study design
- chamber experiments inside an office room: d-limonene was injected into an inner chamber at three levels of relative humidity and ozone was introduced either from a generator or by the natural transport of outdoor ozone into the building, while the particle number and size distribution and the indoor ozone were measured (class 4)
- Effect
- share-above 20
- Caveat
- a joint conclusion of this study and of the office-building study of Weschler and Shields, reference 18 of this paper; the estimate repeats the threshold of the sentence because the sentence gives no share
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.
