- What is the Exposure Level in the MoldReport™?
The Exposure Level indicates how high the spore count per cubic meter is at the time of sampling.
It is reported because if there are indications of a low probability of mold growth at the time of
sampling but the outdoor ambient levels found are high, this might erroneously lead to the conclusion
that indoor mold growth is occurring. Also, the average amount of air that an individual breathes
daily is approximately 3 cubic meters and thus gives an indication of how many spores are being
inhaled daily if the samples are taken under normal conditions.
- On the Chain of Custody what does "ST" represent?
ST stands for spore trap.
- On the Chain of Custody what does "DE" represent?
DE stands for direct examination.
- Why is an outside sample necessary for a spore trap analysis?
In order to use indoor samples to help identify indoor growth, it is necessary to understand
some of the outdoor contributions. Normally, most of the fungal spores found in indoor
environments come in from outside, which is a nautral process and is not usally of concern.
- If I did not take an outside sample, can I still have my spore
trap sample analyzed?
Yes. But inside-outside comparisons cannot be provided.
- Is an outside sample necessary for a Direct Examination?
Direct examination of bulk samples does not require outdoor samples.
- Can weather conditions affect mold sampling?
Weather conditions strongly affect the outdoor aerosol. This is one reason why
you need to sample outdoors at each site where indoor samples are collected. The sampler
should be protected from rain and oriented "into the wind".
- Can I (a homeowner) perform sampling myself? Or do I need a professional to
perform the sampling?
It is important to have a trained professional collect air samples. A
professional mold inspector
does not rely only on air sampling results to decide whether or not a home has a
Carefully conducted mold sampling is combined with visual inspections and discussions
with the homeowner. In addition, many different factors affect the reliability of
an air sampler. The professional mold inspector understands these variables and
accounts for them in the sampling plan.
