Finding F-1399

“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: Ultrafine particles (UFP)
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 18.8
Caveat: the standard deviation is more than twice the mean, so the emission varies strongly between motors; the text layer prints the unit as cm− 3, with the exponent separated
