About Mold

The most common types of mold found indoors include:

  • Aspergillus
  • Cladosporium
  • Penicillium
  • Alternaria
  • Stachybotrys atraaka Black Mold.

Often, mold spores, whether dead or alive, cause adverse health effects, primarily of a respiratory nature, including hay fever-like allergic symptoms.

Many of these molds, primarily S. atra, also produce chemical toxins known as “mycotoxins,” which are generated and released into the air within the mold spores, leading to the “toxic mold” designation. Exposure to these toxins can occur through inhalation, ingestion, or skin contact, and can result in symptoms including dermatitis, cough, rhinitis, nose bleeds, cold and flu symptoms, headache, general malaise and fever.

Initial awareness of adverse health effects from S. atra exposure was raised by a mid-1990’s study from Cleveland, Ohio, involving infants who had died from sudden and unexplained pulmonary hemorrhage (bleeding of the lungs). Upon investigation, researchers found that the infants resided in homes with high levels of S. atra, linking S. atra exposure to serious health effects.
