Airborne Fungal Spores

Fungal spores and especially mold spores are a normal component of the outdoor air. They are microscopic structures that function as “seeds” to allow fungi to reproduce. Apart from acting as “seeds” for reproduction, many fungal spores are adapted for dispersal and for survival, often for extended periods of time, in unfavorable conditions. Airborne Fungal […]

Airborne fungal spores exposure limits

A common question often asked is what are the airborne fungal spores exposure limits in both indoor and outdoor environments? In other words, what are the maximum spore concentrations that a healthy person can inhale without getting sick? While there are no universally acceptable airborne fungal spores exposure limits, existing evidence suggests such limits would […]

How To Interpret Laboratory Results for Airborne Fungal (Mould) Samples

Laboratory results for airborne mould and bacteria concentrations can be difficult to interpret for two major reasons. Maximum exposure limits have not been set Currently, there are no set maximum exposure limits (MELs) or threshold level values for airborne indoor mould and bacteria concentrations. Setting MELs would be difficult for reasons which include limitations in […]

Guidelines for Interpreting Numerical Data of Non-viable (Spore Traps) and Viable Airborne Mould Samples

In this article we discuss additional guidelines for interpreting numerical data for viable and non-viable airborne mould samples. The guidelines may be used to decide whether further investigations are required after initial investigations. However, numerical laboratory results cannot be used as the primary determinant of whether there is a mould problem but should always be […]
