Question: My house just got tested for mould. The outside test was 67 spores per cubic meter of air. The inside was 24,000 spores per cubic meter of air for Aspergillus/Penicillium type.
I heard the city of Calgary has a standard that says you double the counts for control/outside and add a hundred for acceptable limits of the inside. Do you have a link for this?
What health problems can this be associated with in the long term?
Answer: Yes, the Calgary Health Region has developed a mould guideline entitled “Fungal Air Testing, Investigation and Reporting Requirements for Residential Marihuana Grow Operations” which provides guidelines on how to interpret air sample results. They have also developed “MARIHUANA GROW OPERATION REMEDIATION GUIDELINES.”
The long term effects of mould exposure varies with individuals. Some people may develop sensitivity to mould.
