Post: Average Outdoor Spore Counts
Posted by Rem Dude on 2/25/08
The average outdoor Cladosporium spore counts are:
Florida - 7627 spores per cubic meter.
California - 6987 spores per cubic meter.
Colorado - 5546 spores per cubic meter.
Arizona - 2987 spores per cubic meter.
Hawaii - 14,325 spores per cubic meter.
Illinois - 12,651 spores per cubic meter.
Maryland - 9027 spores per cubic meter.
Ohio - 13,229 spores per cubic meter.
Texas - 15,550 spores per cubic meter.
Except for Arizona, we seldom find indoor levels of
Cladosporium at these average outdoor levels. The
exception is a flood damaged house that has been allowed
to fester for a week or more. However, for the average
mold-in-a-wall-cavity, crawlspace, or attic situation, we
seldom exceed these published outdoor levels. And
remember, these are historical averages, there are many
days where the outdoor level far exceeds these numbers...
