Stacybotrys Mold Home Truths

Friday, April 13th, 2007

There are many misconceptions about one of the most toxic household molds, Stacybotrys. As our project leaky house is contaminated with Stachybotrys, and I personally have suffered from Stachybotrys poisoning, I think it is worth discussing before we end our section on planning.

Growth

Stacybotrys mold requires four key elements for growth:

  1. Moisture – from leaky building envelopes, environmental disasters, chronic leaky pipes
  2. Nourishment – high cellulose, low nitrogen building materials
  3. Temperature – generally high temperature fluctuations
  4. Time – takes 1-2 weeks to start growing, compared to most household molds that appear in 1-2 days

Appearance
The mold can have several appearances based on moisture content – from a thick black-green slimy appearance to a black powder. As other household molds can also share these characteristics confirmation of Stacybotrys is only possible by laboratory test.

Dispersement
The mold can spread by tendrils containing spores. Spores are only released [BUT NOT ALWAYS] when the mold has dried out and is disturbed. Spores will generally only live 24-48 hours, but can release powerful mycotoxic chemicals which cause allergic reactions in SOME people.

Symptoms of Exposure To Stacybotrys
Symptoms vary depending upon the type of duration of exposure.
Long term occupation in a mycotoxic environment can lead to symptoms such as:

MILD – anging from cold and flu symptoms to memory loss, muscle aches, sore throats, diarrhea, headaches, fatigue, dermatitis.
MODERATE – intermittent local hair loss, upper respiratory infections, fungal or yeast infections, and urinary tract infections and generalized malaise.
SEVERE – suppression and destruction of the immune system, hemorrhage in the lungs, DNA damage and cancer.

Building Remediation
Fixing a leaky building containing Stacybotrys is not a difficult task but is one that should be treated with extreme caution.

  • Personal protective clothing such as masks, googles, gloves and disposal overalls should be worn
  • Areas being treated must be suitably contained
  • Proper procedures must be floowed, both for protection of those working on the remediation and anyone occupying the building.
