Their study found that ‘toxigenic fungi’ present in indoor environments can produce toxic, airborne compounds which can be inhaled by residents.
“We demonstrated that mycotoxins could be transferred from a moldy material to air, under conditions that may be encountered in buildings,” Bailly said. “Thus, mycotoxins can be inhaled and should be investigated as parameters of indoor air quality, especially in homes with visible fungal contamination.”
The health impacts of mould have been a particular issue in Australia recently, after the past few weeks of wet weather resulted in huge outbreaks of the fungi.
