Finding F-1400
“Specifically, the average number of emit ted particles across all measurements was 18.8 ± 43.6 cm− 3 in the 10–100 nm range (nanoparticles), compared to 2.0 ± 7.5 cm− 3 in the 100–421.7 nm range (fine particles).”
Structure
- Factor
- Particulate matter (PM₂.₅ and PM₁₀)
- Setting
- laboratory
- Study design
- laboratory measurement of airborne nanoparticle emissions from the electric motors of household appliances: particle number and size distribution measured in the 10 to 421.7 nanometre range across repeated measurements on several motors (class 4)
- Effect
- mean 2.0
- Caveat
- the standard deviation is far larger than the mean; the text layer prints the unit as cm− 3, with the exponent separated
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.
