Environmentally Friendly Mold Remediation Techniques That Significantly Reduce Childhood AsthmaTotal Mold Counts Miami National Allergy Bureau05/13/2004 - 11/09/2004(Counts are total mold per cubic meter of air)4. Failed RemediationThe Outdoor Air Comparison MythThe graph above shows outdoor mold spore counts taken in Miamiduring a six month period in 2004. The results show that total sporecounts vary widely from day to day throughout much of the year.Based on the reading of the chart, we see that outdoor counts can be10X-20X higher (or lower) a few days later or earlier. This proves thata simple comparison of indoor spore counts to outdoor levels inMiami cannot generally be used to judge whether remediation hasbeen successful. Even more extreme variations in outdoor sporecounts can be seen if other locations in the U.S. or seasonal issues arefactored in.Sarasota, Florida – which is on Florida's humid gulf coast – typicallyhas in the range of 20,000 spores per cubic meter of air in thesummer. On the other hand, outdoor counts in the Northern U.S. inthe winter – or Las Vegas almost any time – typically would be about1000 times lower.In addition to the outdoor counts, the composition of outdoor moldspores can vary from day to day.
