Mould Spores Air Quality

New Mould Spores Air  Quality

To capture and quantify a broad spectrum of fungal spores (both culturable and non-culturable) present in the air.

To assess whether the levels present suggest a fungal problem in the indoor locations.

Spore trap samplers are capable of capturing a majority of spores and particulate matter in the air. Consequently, it is possible to accurately characterize problem environments where spores are present but either are no longer viable or are species that do not culture well. These are two situations where culturable sampling techniques, if used alone, may miss a potential IAQ problem.
Currently there are no numeric standards for airborne or surface microbial contamination indoors. Suggested guidelines are constantly being reviewed and edited as more information surrounding microbial IAQ issues surface.
Fungal spore trap air samples are collected using a sampling cassette attached to a high volume vacuum pump.  Air is drawn through the cassette and the contents of the air are deposited upon a sticky glass slide which is then analyzed by an analyst who identifies fungal types and quantity.
Spore trap sampling is a tool that provides a snapshot of the types and concentration of airborne fungal spores (viable and non-viable) present in the indoor environment at the time of sampling.
Mould Lab Ireland provides spore trap analysis for a variety of sampling cassettes including , Air-O-cell.  Analysis includes identification to genus or group of all fungi present, quantification to spores/m3 and spore type.

A general assessment of background debris is determined.


•  Useful for initial site testing, especially if fungal growth is not visible.
•  Can reveal presence of hidden mould.
•  Easy to use and handle in the field .
•  Low chance of sample contamination.
•  Provides rapid turn around time.
•  Rush analyses available upon request.

Spore Trap Results Interpretation.

To date there are no standardized methods for analyzing spore traps. There are at present no strict numerical guidelines which are appropriate for assessing whether the contamination in an area is acceptable or not.

Keep in mind that the results of the total spores (raw counts) are used only for screening purposes and that the spore concentration has a statistical deviation depending on the analyst.

The amount of fungal spores present in an air sample is highly variable. Changes in airflow, humidity, light level and temperature can all trigger a spore’s release. A single air sample will often underestimate the fungal contamination in the air.

Compare total concentrations of fungal spores from outdoor and indoor samples. Generally, indoor fungal spore concentrations are lower than that of the outdoors. This comparison is not valid when the outdoor sample was taken during or immediately after precipitation. It probably is not valid during some winter months where outdoor fungal counts are usually below that of the indoors.

Compare fungal spore types from indoor and outdoor samples. Fungal spore types from indoors and outdoors should be generally similar. When you compare indoor and outdoor spore types you should consider the following:

a.   Fungal species are present in the indoor sample and not in the outdoor sample.

b.   The predominant fungal species found in the indoor sample is different than the predominant fungal species in the found outdoor sample.

c.   If there is a difference in the fungal spore diversity between indoor and outdoor samples, this may be an indication of indoor amplification. Look for indicator fungal spores. Some fungal spores, when detected in indoor environments, are good indications of water damage. Spores of Chaetomium, Stachybotrys, Memnoniella and Ulocladium are likely associate with water-damaged buildings. When Aspergillus/Penicillium-like spores found in indoor samples are significantly higher than that of outdoors, this would indicate that it is a water-damaged environment. Cladosporium species are common outdoors, however, they grow well indoors on surfaces with high moisture contents. When Basidiospores are detected in air samples, they are likely to come from outdoors. However, basidiomycetes may grow on indoor wood products causing wood decay ifthere is a high moisture related problem.
