EDC1,2,3 refer to different sampler materials
PD petri dish, T TefTex, EDC electrostatic dustfall collector
aIn the USA homes, four samplers were placed at two heights, for a total of eight samplers per home. In the Finnish buildings, duplicates for each of three samplers were employed at a single height, for a total of six samples per building
bDust from different vacuum bags was combined into three different “dust mixes”
cRefers to the mass of dust input into the experimental chamber
