The Poisons and Allergens That Make up Household Dust

How could they not find mold? Not a single mention despite the

dust samples coming from Netherlands, 6 Midwestern states,

and Sacramento. My guess is they looked at the large particles if

this phrase is a clue, " ...Smaller dust particles - from 28 to 49

microns... " That's visible dust. Hair is about 100 microns. Most

mold is 1-10 microns. Most particle studies talk about PM 10 and

PM 2.5 (microns). The ultra-fine particles, which are even

smaller, are becoming a greater concern. Either this is a lousy

study or the news reporting is lousy.

Carl: you are still thinking in the old terminology of particulates. The very

recent research on particulates from Seo, Vesper, Roponen has clearly shown that

very fine particles are present at many fold greater concentrations than are the

larger particulates at 2.5 PM 10 and higher.
