About Black Mold

Black mold is formally named, “Stachybotrys”.  It is a fungus that naturally grows on decayed plant matter and soil.  However, black mold can find suitable substances in our indoor environments, thus posing structural and health problems.  Black mold may begin to grow as a result of flooding, leaks, and high humidity.  An indication of the possibility of black mold growth is black discoloration on water damaged building materials such as ceiling tiles, sheetrock, insulation, gypsum board, and wallpaper.   Black mold can also grow on paper and textiles, such as upholstered furniture, draperies, carpeting, and other fabrics around your home.

Many different circumstances can cause black mold spores to dislodge from the materials where they grow, and infiltrate the indoor air environment.  This is when black mold becomes potentially problematic to your health.

Black Mold and Indoor Air Environments

Black mold has the potential to produce toxins that when airborne may create an unhealthy indoor air environment.  The toxins include:

  • Cyclosporins
  • Macrocyclic trichothecenes
    • roridin E
    • satratoxin F
    • satratoxin G
    • satratoxin H
    • sporidesmin G
    • trichoverrol
    • verrucarin J
  • Stachybotryolactone

Because of black mold’s potential to produce mycotoxins, stachybotrys, more commonly referred to as “black mold”, is linked to Sick Building Syndrome.

Exposure to Black Mold

Aside from inhaling indoor air that may be affected by mycotoxins produced from stachybotrys, contact may also occur through ingestion and / or skin exposure.1 This exposure may cause symptoms to the occupants of indoor spaces with indoor air affected by these mycotoxins.  The elderly, infants, and individuals who are immunocompromised are at highest risk from exposure to indoor air that is affected by black mold.  Also, individuals who are allergic to mold are at higher risk for allergic reactions.

Black Mold Symptoms

Exposure to black mold, specifically stachybotrys, can cause symptoms in different individuals which vary greatly depending on the individual.  Symptoms that have been reported so far include, cold-like symptoms, rashes, conjunctivitis, sinusitis.  It has also been reported to trigger asthma symptoms in certain individuals.  Other symptoms related to black mold include fatigue, and lessened mental clarity.  Still unproven, yet reported by some, is the possible link of stachybotrys atra to pulmonary hemosiderosis.  (bleeding in the lungs of infants younger than 6 months old)2

The Truth About Toxic Black Mold

You will find a lot of information around the internet about “toxic black mold“.  The truth of the matter is the presence of any mold has the ability to create health symptoms in individuals.  All species of mold are considered to be “allergenic”, meaning that exposure to the spores may or may not cause an adverse health response to occupants.  Some individuals are particularly sensitive, while others may experience no symptoms at all.

Although a mold allergy is the most common problem caused by exposure to mold, mold can cause illness without causing an allergic reaction. Mold can also cause infections, or irritant and toxic reactions. Infections caused by mold can cause a variety of problems from flu-like symptoms, to skin infections and even pneumonia.

An irritant reaction is caused when substances from molds called volatile organic compounds irritate the mucous membranes in the body. Symptoms of an irritant reaction are similar to an allergy and include eye irritation, runny nose, cough, voice hoarseness, headache and skin irritation. With a mold allergy, your symptoms will generally get progressively worse with each exposure to mold, while an irritant reaction doesn’t get worse.

A toxic reaction to mold is caused by eating, drinking or inhaling substances called mycotoxins. As with an irritant reaction, the symptoms of a toxic reaction may also include flu-like symptoms, eye and skin irritation, and breathing troubles. You may also experience headaches, nervousness, dizziness, difficulty concentrating and extreme fatigue if you’re having a toxic reaction to mold.3


Therefore, whether the mold growth in an indoor air environment is found to be stachybotrys, “toxic black mold”, or any other species of mold, it is always recommended to remove mold in a timely manner.  When left to grow, a mold problem can become exponentially worse with time, causing more damage and more costly repairs in the end.

All Species of Mold are Considered “Allergenic”

Similar to pollen, mold carries the potential to create allergic reactions in certain individuals.  These symptoms vary widely, and may range from barely-detectable to severe.  Some allergic reactions to the presence of mold include cold-like symptoms (sneezing, runny nose / stuffy nose, itchy and / or watery eyes, itchy throat, coughing, & postnasal drip).  If you experience any of these symptoms, we recommend that you consult with your doctor.3
