Should I Be Concerned About Mold?

ASK A NORMI EXPERT

This article is a reprint as it was published in www.ForSaleByOwner.com Vol 7 Issue 7 New Orleans, LA
"Should I be concerned about mold and mildew or is this just another scare tactic?"
I recently performed an aerobic (air) mold test on a house near the beach in St. Petersburg, Florida. This came from a lead I received from an ASHI (American Society of Home Inspectors) Home Inspector with whom I work closely on such problems. He had seen some mildew in the master bedroom closet ceiling and was concerned that it might be more than just your average strain. Because he is very aware of the potential problems with toxic molds, he decided to give the realtor my name and she called to inquire about our services.
I told her about our Microbiological Test Kit for all types of mold and mildew and that it would be important to know what kind of mold is present before you start any remediation process. She responded by asking, "Should I really be concerned about mold and mildew or is this just another scare tactic? Why can't I just bleach this stuff and paint over it?" I was shocked by her question and wondered how she could be so unaware of the real health concerns now associated with toxic molds.
Molds are microscopic organisms found virtually everywhere, indoors and outdoors. Many of our building materials are especially susceptible to promoting mold growth and so our indoor environments can readily become incubators for all types of mold and mildew. When you add a little more moisture and a cool place to hide, mold and mildew can take over an area very quickly. One professor at LSU said, "Our homes are just giant petri dishes!" Therefore, the sources of mold problems in your home or office can be: flooding, leaky roofs, humidifiers, damp crawl spaces, constant plumbing leaks, excessive numbers of house plants, steam from cooking, shower/bath steam, wet clothes, and even your air conditioning system itself. Once disturbed, mold sends out spores (similar to seeds) and those spores can reek havoc on your sinuses and respiratory system.
Exposure to mold can be a health concern for anyone but is especially troublesome for infants, children, elderly, immune compromised patients, pregnant women, and individuals with existing respiratory conditions. A wide range of health problems including wheezing, nasal and sinus congestion, watery and red eyes, nose and throat irritation, fevers, asthma, emphysema and other symptoms result from ingesting these mold spores. The cause may be mold that you cannot see.
But what about toxic mold? Stachybotrys Chartarum. Sounds ominous, doesn't it. Stachybotrys is a greenish-black toxic mold that colonizes particularly well in high-cellulose material such as straw, hay, wet leaves, dry wall, carpet, wall paper, fiber-board, ceiling tiles, thermal insulation, etc. Before drying, Stachybotrys is wet and slightly slimy to touch. The toxic mold grows in areas where the relative humidity is above 55%. Sounds like New Orleans, doesn't it? So it shouldn't surprise us to find cases of the toxic mold in the Crescent City and surrounding areas. Remember the family in Chalmette that moved out of their apartment last year because of toxic mold? Stachybotrys produces a mycotoxin that causes mycotoxicosis. This type of mold is thought to be a possible cause of the "sick building syndrome" and a multitude of "building related illnesses". Children's exposure to this mold is thought most likely to cause pulmonary hemosiderosis (bleeding in the lungs). Wouldn't it be important to know if Stachybotrys is present in your indoor environment? When the Florida realtor asked me about toxic mold, I only needed to direct her to her favorite Internet search engine. By typing in "toxic mold" she was introduced to a whole new world of articles and news stories regarding the real dangers of toxic mold. So here's the happy ending for her and her client: I was able to test the house for mold presence, suggest a reasonable remediation process, and assure the homeowner that toxic was NOT present.

Fresh Air Ideas

Good April 12th to you! Sorry I missed last month but I have been busy in the field solving air issues. I also received my Mold Inspector Certification. As a Certified Mold Inspector I will be bringing more air quality news to my followers. This week however I would like to post a video for a solution to some of the residential IAQ problems out there. I would also like for all of you to send subjects you would like to know about in the IAQ industry. Please e-mail   rlfreshair7@gmail.com
Please enjoy this informative video.   http://youtu.be/xu0nRBATVzo

Why Is Humidity A Problem?

Why would humidity pose a problem in our homes? Excess humidity can create a haven for growth of fungi, mold, bacteria, etc. Too low a humidity content and we have static electricity, dry skin, dry sinuses, etc.
Let's address excess humidity and the issues that arise.
Mold loves dark moist spaces to grow. The moisture on building materials along with the microbes that are food for mold creates a "dining haven" if you will. When there is water damage the moisture of course is soaked in and no longer just a surface problem. The mold spores that are in the air already settle down in the moist environment to "feast" and grow. The moisture on our air conditioning coils is a great place for fungi and mold to propagate (dark & moist).
How do we combat these problems? We'll cover that another time.
Next time Temperature.

What Gases Should We Be Concerned About?

Gases--another component of unhealthy IAQ. What are examples of these? Any spray fragrance, perfume, deodorant, insect spray, and repellants to name a few. Other examples are the "off-gasing" that occurs from flame retardants in fabrics, chemicals in carpets, furniture, paint, etc. Our cleaners under our sinks produce unhealthy gases. We are bombarded with these gases in our sealed up energy efficient homes.
Sometimes there are odors associated with these gases sometimes they are just silent and slowly deadly.
Sounds pretty overwhelming doesn't it? What is the solution?
We'll cover that another time. Next time humidity.

What Are Bio-Pollutants?

What are bio-pollutants? The term sounds ominous doesn't it? Well it can be.
Bio-pollutants are things like mold, e-coli, salmonella, and other such bacteria, viruses and fungi. They all can affect our health if absorbed by our bodies.
These organisms are in the air, on surfaces and can be transmitted by contact of any kind.
Some of the ways to avoid these are being careful to clean surfaces when preparing food, making sure trash and garbage does not overflow, use green cleaning supplies, use air purifiers, use proper air filtration, and last but not least common sense.
Next time  we'll cover Gasses.

Are Odors Just Bad Smells?

What are odors? Why is it a concern for IAQ? First of all odors are an indication of something else going on. For instance: musty odors could signal mold growth and off gassing. Rotting odors could signal bacteria growth. Odors signal something beneficial or harmful in our indoor environment. Odors can signal VOC off gassing which is harmful to the occupants. Odors can signal mycotoxins as small organisms digest their food source of dust, skin cells etc. All of which cause our bodies to have to react to the invaders in our breathing passages. Odors are to be taken seriously, not just a bother.
Closely related are the bio-pollutants which we will cover next time.
