A recent study conducted by French researcher Jean-Denis Bailly and his colleagues has found that mycotoxins from mold can disperse into the air under normal conditions.
The researchers examined the mycotoxins produced by three types of fungi, and discovered that “this transfer to air requires air velocities that can be encountered in ‘real life conditions’ in buildings.”
These aerosolized mycotoxins pose a health risk for the occupants as they can be easily inhaled and can penetrate into the respiratory tract.
The researchers further noted that approximately twenty percent to forty percent of buildings in Northern Europe and North America have macroscopically visible fungal growth. Therefore, it is crucial that any risk assessment regarding fungal growth in buildings takes these findings into consideration.
