Many molds are black in appearance but are not Stachybotrys. For example, the black mold commonly found between bathroom tiles is not Stachybotrys. Some related symptoms are more general - such as inability to concentrate and fatigue. Usually, symptoms disappear after the contamination is removed. There has been some evidence linking Stachybotrys with pulmonary hemosiderosis in infants who are generally less than six months old.
Pulmonary hemosiderosis is an uncommon condition that results from bleeding in the lungs.
In studied cases of pulmonary hemosiderosis, the exposure to Stachybotrys came from highly contaminated dwellings, where the infants were continually exposed over a long period of time. There is no simple and cheap way to sample the air in your home to find out what types of mold are present and whether they are airborne. Even if you have your home tested, it is difficult to say at what levels health effects would occur. Therefore, it is more important get rid of the mold rather than find out more about it. The most effective way to treat mold is to correct underlying water damage and clean the affected area.
