One of the most common questions we encounter pertains to black mold. The purpose of this article is to explain what black mold is, why it grows, and the potential health consequences of exposure.
What Is Black Mold?
What Is Black Mold?
Stachybotrys molds decay organic matter. The most common species, Stachybotrys chartarum, sometimes referred to as Stachybotrys atra often grows indoors.
Ideal conditions for Stachybotrys growth include moisture, a nutrient/food source, temperature, and time. Ideal humidity for this black mold is a relative humidity of 90% or higher for it to begin the germination growth process. Stachybotrys feeds on materials with a high cellulose content such as hay, straw, wood chips, and building materials such as ceiling tile, drywall, paper vapor barriers, wallpaper, insulation backing, cardboard boxes, and paper files.
Stachybotrys is considered the King of Molds because it will develop into the dominant mold group if the conditions are favorable and will crowd out the other molds that began feeding on the material first.
This happens because unlike other molds like Aspergillus, Penicillium, and Cladosporium which begin growing within one to two days, Stachybotrys takes one to two weeks to begin growing.
Don’t Disturb Black Mold!
Don’t Disturb Black Mold!
When Stachybotrys mold is growing on wet material, the spores do not disperse as easily because the spores are held together by a sticky/slimy coating. However, when the material dries out or is disturbed, the spores will spread through the air.
The main concern of a mold remediation contractor is to prevent the spread of toxic black mold. The most effective method of doing this is through containment, which is the process of creating a poly barrier around the area where the Stachybotrys mold is growing.
This procedure is so important because Stachybotrys spreads by releasing spores. Mold contaminated materials must be removed and disposed of because this mold does not just grow on the surface of the material; it has root-like tendrils called mycelia, meaning it is able to penetrate the surface.
Typically Stachybotry mold grows in clusters at the end of stem-like structures known as hyphae.
Stachybotrys black mold is a health concern because animal studies have shown that one of the major effects of trichothecenes is immuno-suppression.
In fact, even low level exposure can suppress the immune system resulting in bacterial and viral infections, coughing, skin irritation, and other allergic reactions, and there is some speculation that it may even cause cancer.
Listed below are the top 15 health conditions caused when toxic Stachybotrys black mold is inhaled or ingested:
Sore/hoarse throat
Cold and flu symptoms (headaches, slight fever, and muscle aches)
Nosebleeds
Tingling or burning of nose, mouth, and perspiration areas (under the arms or between the legs)
The initial instinct when you find mold is usually to reach for a spray bottle and try to kill it with bleach. Our advice, don’t panic and never reach for a bleach bottle, particularly if the mold is on porous materials like drywall. As stated by mold survivor, Christa Upton:
Don’t “kill” or spray mold! Instead, properly remediate it and hire a professional with experience and references that knows what they are doing…. We “killed” mold, sprayed with Lysol, bleached sub-floor and ran fans, replaced carpet but left mold in the sub-floor, walls, etc. Eight months later I was so sick I could not get out of bed….Not one spray has been shown to denature these toxins. Some sprays appear to make toxins worse or more airborne. Humans cannot smell most mold toxins, especially after the mold is “dead.” They are so small that they cannot be seen. They are so tiny that they generally cannot be removed with air purifiers or filters. But they are deadly.
“Killing mold, but leaving the residue in place, is not acceptable. Since many health impacts can be triggered by exposure to both live and dead mold spores, the source and secondary contamination must be removed.” (MOLD INDOORS: Killing it is Not Enough)
One of the problems with the mold is the fact that there is so much bad information on the Internet that recommends that it is safe to try to kill mold. In the case of Christa, this proved to be dangerous to her health.
Unfortunately, because of the lack of regulation in the mold remediation industry, even some contractors believe that killing mold is the answer. Generally speaking, these contractors are poorly trained and really do not understand mold. There is no “quick fix” for mold contamination situations. As a consumer, you need to be cautious about hiring contractors that offer magical solutions that involve just spraying a chemical to kill the mold dead. The purpose of this article is to educate you on mold basics and expand on why killing mold is not the answer.
5 Mold Facts You Need To Be Aware Of!
5 Mold Facts You Need To Be Aware Of!
Mold thrives when moisture is present. Removing mold without addressing the cause of the problem, ie. identifying the moisture source is not a long term solution. Before any mold removal, the moisture problem must first be found and fixed.
Exposure to mold spores, both live and dead, and their byproducts like microbial volatile organic compounds (MVOCs), mycotoxins, connecting filaments, etc. can cause illnesses ranging from minor allergic reactions, respiratory problems like asthma and sinusitis, to more serious, life threatening illnesses.
Mold is a biological agent that will continue to grow as long as the right conditions exist. This is the reason that mold is such a concern because it will continue to thrive and grow unless it is removed and the underlying moisture cause is fixed. In short, ignoring a mold problem will make the situation worse and pose more dangers.
“Perhaps the most misunderstood aspect of bleach when proposed as a cleaner or sanitizing agent is that its effectiveness is greatly reduced in the presence of organic material. To be a successful sanitizer, bleach must be used on clean materials and surfaces. This is why bleach products are used in the laundry after the wash cycle or in a commercial kitchen as a component in the third sink after the dishes have been washed and rinsed. The efficacy of bleach as a sanitizer is also compromised by heat and light. Despite the fact that the chlorine odor may linger for some time after use, bleach loses strength so quickly that it is not considered to have a residual effect that would prevent future bacterial or fungal growth.” (Michael Pinto, Why Restoration Professionals Should Avoid Using Bleach)
One of the benefits of the Internet is it allows anyone to search for a topic of interest and find the information they are looking for.
Unfortunately, with respect to mold removal, the bleach myth is perpetuated on the Internet on countless websites.
Bleach may have some impact on non-porous materials, like bathroom tiles, but bleach is completely ineffective on porous materials:
“If you spray bleach all over your “black toxic mold” you won’t kill every single spore….To kill every single mold spore using bleach, for example, you’d have to use such a high concentration of disinfectant and you’d have to keep it on the surface for so long that more likely you’d damage the structure – and still miss some toxic spores.” (How to Kill Mold – Do We Want to? Is Dead Mold Dangerous?)
Other reasons we do not recommend the use of bleach:
Bleach does not address the cause of the mold problem!
Bleach is dangerous!
Bleach evaporates!
Bleach Does Not Address The Cause Of The Mold Problem!
Experienced mold removal specialists understand that the most effective way to deal with mold is to first find the moisture source and make sure it is fixed.
The next step is to remove the mold contaminated porous materials.
Proper removal of mold contaminated materials like drywall, carpet, soft goods, insulation, and other porous materials is essential because mold has hyphae, which are basically roots that embed themselves in the material.
This is the reason that bleach does not work. Bleach may kill some of the surface mold, but it will not be able to penetrate and kill the roots.
The other reason bleach is a problem is that it is diluted with water. Spraying this is counter-productive because water is an essential ingredient mold needs to grow.
Keep in mind, even if another biocide or fungicide is sprayed on the material, killing the roots, the material will still be contaminated with dead spores. The best course of action to permanently deal with a mold problem on porous materials is to properly dispose of the contaminated material.
Bleach Is Dangerous!
When you are using bleach you should always wear gloves, goggles, and a respirator for three key reasons.
Bleach is a corrosive that could irritate and damage your skin.
During the spraying and evaporation process, bleach releases chlorine gas that will impact the eyes and respiratory system.
One of the by-products of chlorine bleach are dioxins, linked to cancer.
If you intend to use bleach for household cleaning projects, never mix it with other cleaning solutions or detergents that contain ammonia because toxic fumes will be produced.
Bleach Evaporates!
The core ingredient of bleach is chlorine. Over time, chlorine can evaporate and escape through the plastic container. In short, the longer bleach sits, the more ineffective it will become because the chlorine dissipates.
Dead Mold Spores Are Harmful!
Dead Mold Spores Are Harmful
“Even if in theory we could “kill” every spore, the assumption that they are unimportant is highly questionable. “Dead” spores often contain allergens or toxins that are just as harmful to someone breathing them or getting such mold in one’s eye or in a cut, as before….The object is not to “kill” mold, it is – to remove the mold reservoir in the building by physical cleaning or in cases of items that can’t be cleaned, such as drywall, soft goods, carpets, furniture, or insulation, remove the moldy material – to identify the cause and make sure that’s been corrected.” (How to Kill Mold – Do We Want to?
