What is toxic black mold?
Despite the commonly held belief that black mold exposure is a serious health concern, no convincing research suggests that exposure to this type of mold causes conditions such as cancer or lung disease.
Mold is a type of fungus. It is present almost everywhere, including the air. In general, normal amounts of mold in the environment do not pose a substantial health risk to healthy people with a healthy immune system function.
There is no single type of mold called "black mold" — many molds are black. When people use the term, they may be referring to a type called Stachybotrys chartarum (S. chartarum), also known as Stachybotrys atra.
There is no scientific evidence to suggest that exposure to S. chartarum is more dangerous than exposure to any other type of mold.
