Stachybotrys Chartarum aka Black Mold

Black Mold or Toxic Mold usually refers to Stachybotrys chartarum.  Stachybotrys chartarum is a greenish-black colored type of mold. It commonly grows in places that have a constant water source i.e. leaking pipes, and high cellulose material, i.e. sheetrock.

Toxicity and mVOC

Certain types of mold, like stachybotrys produces airborne mold spores, mycotoxins, which can pose health risks to immunocompromised individuals. The compounds produced by molds have strong smells and are volatile and quickly released into the air. These compounds are known as microbial volatile organic compounds (mVOCs). Because mVOCs often have strong or unpleasant odors, they can be the source of the "moldy odor" or musty smell frequently associated with mold growth.

Mold is Everywhere Naturally

All spores found in indoor air are also normally found in outdoor air because most originate or live in the soil and on dead or decaying plants. Therefore, it is not unusual to find mold spores in indoor air.  When the media reports warn about the dangers of black mold and these stories can be alarming and confusing. Remember, any mold in your home should be treated with caution. We suggest to stay out of affected areas and don’t touch or disturb the mold.
