Citando:
"(...) Particles shed by several species of fungi (that we'd commonly think of as mould) can contain chemicals called mycotoxins, and that the toxins themselves can also become airborne.

For people with asthma and other allergies, the mould particles themselves can be a nightmare, inflaming the lungs and sinuses and causing anything from sneezing and itchy eyes to restricted airways and asthma attacks.

This is usually caused by the body's immune system becoming sensitive to compounds in the spores and hyphae or to waste products called microbial volatile organic compounds, and not specifically the mycotoxins.

Usually, mycotoxins are substances we'd associate with food contamination as they leach out of fungi growing on fruit or grains. Nobody is sure why fungi produce them, but consumed in high enough concentrations they can be deadly.

While their effects on the body after being ingested have been studied extensively, less is known about the effect of breathing in mycotoxins, or whether it's even something to consider as a potential health concern for most of us.

"There is almost no data on toxicity of mycotoxins following inhalation,""
