The sample is then taken to the laboratory for microscopic identification. Once the mold is identified, the investigator is able to issue a finding and specific recommendations for each case.  <\/span><\/p>\n\n<p><b>Dust collection<\/b><\/p>\n\n<p><span style=\"font-weight: 400;\">The mold hidden inside the walls has chosen as a means of reproduction to launch spores (tiny particles) into the air.<\/span><\/p>\n\n<p><span style=\"font-weight: 400;\">These spores are heavier than air and, consequently, end up falling and settling on horizontal surfaces (tops of cabinets, furniture, frames, etc.). The spores are therefore mixed with the dust normally found in a house. Following a culture in the laboratory, an analysis protocol of this dust allows us to identify and count each type of mold. This operation allows us to obtain a health index qualifying the quality of the air in the residence.<\/span><\/p>\n\n<p><b>Direct air sampling<\/b><\/p>\n\n<p><span style=\"font-weight: 400;\">Unlike dust sampling, where the spores collected may have been present for several weeks, air sampling gives us a direct reading in real time. This means that the spores collected will reflect the conditions present during the investigation. This type of sampling is most often used in areas where there is little or no dust, such as office buildings, specialized clinics, etc. The protocols require a minimum of two samples to be taken, one inside and one outside the building to allow for a geographical comparison.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>The importance of air quality in buildings should not be overlooked.
