New weapons in the war on toxic mold

Environmentally friendly building materials may help combat "sick building syndrome" and improve conditions for allergy sufferers......... but read the story below- By Sam Boykin

One family's devastating experience with toxic mold

Sept. 12, 2002
Just days after moving into their new $300,000 home in Austin, Texas , Dawn and Scott Richardson and their two young daughters began experiencing health problems. At first it was the occasional headache, nosebleed or bout of dizziness. They also started having trouble concentrating, and often felt muddled and fuzzyheaded. When a water stain appeared on the ceiling, it was discovered that a leaky air-conditioning line had bred a big patch of black mold in the attic, and spewed water down the walls and under the floors. Five weeks later, as their health continued to deteriorate, the Richardson family abandoned their home and nearly all its contents.

"I was bumping into walls and getting lost in my own neighbourhood," says Dawn Richardson. "The final straw was when my 16-month-old daughter stopped talking. She regressed to primitive grunting and screaming; she lost her coordination and dexterity. The house was literally killing us."

Both Dawn and her youngest daughter, Erica, were diagnosed with neurological disorders and brain damage, as well as autonomic dysfunction and hypotension. Dawn, who has a degree in electrical engineering from the University of Connecticut and used to design microprocessor chips, feels like a part of her has been forever, stolen. "I was pretty damned smart," she says. "And there are areas of my brain now that are permanently damaged. This affects my whole family, especially now that I'm a mother."

In March, the Richardsons sued the builder, claiming that their negligence during the construction process created the optimal environment for the growth of toxic molds and compounds, many of which produce poisonous chemicals that cause chronic and acute health problems, including cancer.

The afflictions plaguing the Richardsons are hardly an isolated incident. An increasing number of people both at home and in the workplace are being affected by sick building syndrome (SBS), defined as situations in which a substantial proportion of building occupants experience discomfort and health effects that are relieved upon leaving the building. In fact, the Environmental Protection Agency has indicated that indoor levels of pollutants are often higher -- sometimes as much as 100 times higher -- than outdoor levels. Moreover, the Environmental Protection Association (EPA) says that sick buildings cause an estimated loss of $61 billion a year in employee absenteeism, medical costs, reduced productivity and lower earnings.

Legal action has been a fast-growing response to the rising incidence of SBS -- proliferating as quickly as mold behind damp drywall. The building industry has responded in kind -- after the Richardsons filed their lawsuit, they discovered that a clause in their construction agreement stipulated that all disputes must be resolved through binding arbitration, a legal condition that has become increasingly common in the construction industry. This means that a designated third party -- one often chosen by builders, contractors and attorneys with ties to the construction industry -- will unilaterally settle a suit, with no judge, jury, right of appeal and often no public record. And even if the Richardsons decide to move forward and prevail in the arbitration, they stand to have tens of thousands of dollars in arbitrator fees deducted from any award.

As concerns and lawsuits have mounted, building and furniture industries have begun to introduce environmentally friendly building materials, toxic-free paints and other products and advances in ventilation technology. The movement isn't as quick as some would like, and it won't do anything to remedy the damage already caused, but it is a sign that the same industry whose phenomenal growth has led to unprecedented health problems is realizing that it has to clean up its act, or suffer the consequences.

There are multiple causes of SBS, but the main culprits are toxic mold and volatile organic compounds. "Molds have an array of biological weapons that they use against each other to compete for available nutrients," says Harriet Ammann, senior toxicologist at the Washington state Department of Health. " And some of them, under certain circumstances, can make toxic materials of varying potency. We sometimes get caught in the biochemical warfare crossfire."

Volatile organic compounds (VOCs) are found in the chemicals used to manufacture and prepare many building materials. Depending on moisture levels and temperature, some of these chemicals evaporate, and if a structure is not properly built or ventilated, the indoor air may become toxic and unhealthy.

"Chemicals like formaldehyde are in the resin used to manufacture most cabinets, wall paneling and closet shelves," says John Bower, founder of the Healthy House Institute, an organization through which he writes books and produces videos on indoor air quality. "They may have a fancy oak, walnut or cherry veneer, but underneath is particle board or plywood held together with toxic materials. The clear finish used on cabinetry and furniture is also a formaldehyde-based chemical. It's so potent that it will burn itself off in six to 12 months. But even after that, the plywood or particleboard under the veneer will continue to off-gas for several more years."

Moreover, as houses, apartments and office buildings are being erected at a record pace, proper building standards are not always followed, particularly when it comes to moisture protection and ventilation. "The only reason mold grows indoors is because of moisture," says Ammann. "And that's a big problem with a lot of modern construction. Houses and buildings are put up in such a hurry with a relatively unskilled workforce."

Bower doesn't think the construction industry will change its behavior quickly. "Based on what I've seen over the past few years, I think it's going to be a slow evolution," he says. "I don't think industry is willing to admit that they made an unhealthy product, but they certainly can say “ We're improving our products, and here are the latest improvements."

"Today consumers have more of a choice whether they buy products that have high or low VOC emissions," says Ammann. "But most people having houses built don't pay attention to that kind of detail. It really requires some research to find these products."

Of the environmentally friendly building materials being marketed, two of the more popular products are Medex, an exterior-grade product originally developed for highway signs, and Medite II, which fills the need for a lower-cost product for interior applications such as cabinets. These materials are bound with "phenol-formaldehyde," which does not off-gas as much formaldehyde as do conventional building products made with urea-formaldehyde. Standardized tests indicate that the formaldehyde levels from both products are well below most indoor air-quality standards.

In addition to low-formaldehyde board manufacturers like Medex, there is a growing number of other environmentally friendly products including non toxic and VOC-free paints and finishes, flooring and roofing materials, as well as a variety of cleaning products. (see our resources page for benign cleaning product information)

Another key feature of a healthy house is sufficient ventilation. You can spend as little as $100 to upgrade your existing local ventilation system such as quieter and more energy-efficient exhaust fans in the bathroom and kitchen. Or you can spend $1,000’s for a general ventilation system, which brings in fresh air and exhausts stale air throughout the entire house. "It's sort of like the difference between buying a used Geo or a brand new Mercedes-Benz," says Bower. "Of course a lot depends on your needs." (see our solutions page)

Most experts stress that to ensure a healthy house, consumers should expect to perform a little homework and due diligence, as well as incur some additional costs (usually around 10 percent more than a conventional home). But if toxins and molds are of a particular concern, it's well worth it.

"If the added expense cuts down on your doctor bills or insurance payments or the possibility of having to destroy the house because of moisture problems hidden in the wall cavity, it's money well spent," Bower says.

Of course not everyone reacts to toxic molds or VOCs the same way, and experts say there is no widely accepted threshold to these toxins. "As with all toxic materials, the amount of exposure is really important," says Ammann. "But we still don't have a good way of measuring the connection between mold exposure and health. That field is still somewhat in its infancy."

"There are people like George Burns who can smoke cigars every day and live to be over 100," says Bower. "Then there are those who are on the hypersensitive end of the spectrum. Say you have a family of five, typically you're only going to see one or two family members that is hypersensitive, unless they just happen to be genetically disposed, or the problems are really severe."

Unfortunately for the Richardsons, their case is a bit extreme in that they fall into both categories. Dawn says that although the builder fixed the leak in the attic, they failed to dry or remove the wet building materials. Subsequent tests by an Austin environmental engineering firm revealed that the Richardsons' house contained high levels of both toxic mold and VOCs such as benzene, benzaldehyde and formaldehyde This graphic example will help us give mold the respect it deserves and always be aware of the danger seek out the cause and treat it immediately.

Ironically, because Dawn has long battled allergy problems, the family had ordered special design features for their new house to reduce the potential of allergens, including all wood and tile floors. (New synthetic carpet off-gases hundreds of VOCs and is a particularly fertile breeding ground for mold and other allergens). But after moving in, they soon noticed the water leaks, and began suffering from a number of health problems. "We started to get sicker and sicker," Dawn says. "But at the time, we had no idea what toxic mold or VOCs were."

The family has been living in a small Austin hotel since abandoning their house last May. The builder paid for the hotel for the first three days, then they dropped us," Dawn says. "Since then we've been on our own, paying two sets of living expenses. We've lost every piece of belonging we had -- clothes, furniture, even the kids' toys.

Here is how Plusaire will help keep your home and family safe from mold spores and moisture and its contaminants !

Because modern homes lack fresh air during the heating season the air inside your house becomes stale allowing moisture from cooking showers breathing etc., starts to accumulate in the air and condensate on to cold surfaces such as windows and exterior walls. A unique solution to winter condensation has been invented by a Canadian and is manufactured in south-western Ontario. The product is called “ Plusaire ” .

One of the reasons for the creation of a product like Plusaire is to address the exact problems associated with winter condensation and indoor contamination from VOCs (Volitile Organic Compounds)and other building materials. Plusaire provides your home with an energy efficient fresh air intake, this fresh cold air dry air when it replaces the stale moist air in your home will eliminate moisture by 70%. “No more mopping up the water”!!!!


We offer a solution that compliments the energy efficient air tight house.

To alleviate the issue of the air held captive by the tightness of the structure and the occupants continually breathing the same stale air, we offer a solution that will provide just the right amount of fresh air.

Now that you are aware of the issues arising from today's higher building standards with homes that are well insulated and built better than ever before you can understand the issues tight structures and construction methods can cause; we have some answers to problems you may be experiencing in our solutions page


If removing mold yourself, wear gloves and a mask for protection. Use non-ammonia soap or detergent in hot water or Sol-U-Mel from Melaleuca with Tea Tree Oil as it is very effective against mold and will prevent re-growth. See our resources page for information on how to contact us to purchase Sol-U-Mel. Scrub the entire area and dry thoroughly. Using strong bleach solutions or straight from the bottle is less effective and highly toxic if you breathe it, so if you need to remove stains use a diluted solution of 10% household bleach. A strong bleach solution can encourage re-growth as bleach damages and deteriorate the surface structure even further were it is applied creating a more acceptable surface for more mold spores to get a hold. Always be sure there is adequate ventilation and dispose of all residue materials in bags. Air ducts can also be contaminated and require anair duct cleaning professional.

Establish the location, cause and extent of the mold presence. Identify and eliminate sources of moisture. Carefully clean disinfect and allow the area to dry while carefully containing the debris as much as possible in plastic. Bag
and dispose of all material and residues. For areas of high contamination, use
a professional service.

The most common indoor molds are Cladosporium, Penicillium, Aspergillus and Alternaria. Stachybotrys (pronounced "stacky-bow-triss") chartarum, known as "black mold," is not uncommon and certainly not rare and requores constant moisture and warmth to grow. Stachybotrys has been known to have toxic properties known as mycotoxins. The presence of mycotoxins is dependent upon the medium on which the mold is growing, ideal conditions like warm temperatures and humidity and damp surfaces provide an ideal environment. Materials most susceptible are fibreboard, wood, gypsum board, drywall, paper, packed dust and lint. Mycotoxins can be found in both living and dead mold spores.

While Stachybotrys mold grows it has a wet slimy layer over the spores and so is unable to become airborne until the mold dries after conditions improve and dry out and this makes removal the dangerous process with this type of mold. If this mold is undetected during the growing stage the house occupants may be unaware of the reason for the contamination or their symptoms as the dampness has disappeared by the time the danger is eminent.

Are modern houses more conducive to mold?

While mold spores have always been around since biblical times and wet damp dark spaces were common places to find mold, today's houses have a uniquely opposite problem. Modern buildings in our effort toward energy efficiency are sealed more tightly than ever before, this causes stale air to continually circulate and contributes to the build up of humidity and heavy moist air. So point to remember, mold spores require warmth and moisture to germinate and grow.

Steve Bauman from Healthy Spaces LLC in Austin, has this explanation: "The shift of the home from a place of safe haven to the role of cause of disease has its roots in the energy crisis of the 1970’s. Since the onset of the energy crisis in the mid-1970’s, the annual increase in the onset of asthma has risen at an alarming rate, an increase in excess of 65%. This can be directly attributable to the tight sealing of homes to save energy. Unfortunately, we've also "locked in" all the indoor air pollutants." [from article by John Hall. "Mold and HVAC Systems" from the Air Conditioning, Heating and Refrigeration News. (June 24, 2002).

Who Is Most At Risk From Toxic Mold Exposure?

For some people, a very small amount of mold spores can create health problems, particularly with asthma and respiratory ailments, while others can tolerate an extremely high amount of spores prior to ill effects.

The harmful effects are created by the mycotoxins and it is this exposure that can trigger many of the symptoms people exposed to mold experience. Those most susceptible to health problems from mold are individuals with existing respiratory conditions or compromised immune systems and allergies particularly those in treatments such as chemotherapy and the elderly. Infants and young children likewise are more susceptible to serious health problems from this exposure as their immune systems are not fully formed and the their small body weight makes them susceptible faster and with less exposure.

Anyone who suspects they may have health problems believed to be due to mold infestation and exposure should seek professional medical assistance immediately.

If you suspect you are ill due to exposure to mold in a building, you should probably vacate the home or building, at minimum until the cause and presence of mold is evaluated and removed, if necessary by professionals.

Evaluation and Clean Up Procedures For Mold

Air borne mold spores are not visible to the naked eye, but you can both see and smell mold once the spores have landed in an ideal environment, germinate and begin to grow. At this point you will experience musty or unpleasantly medicinal and even slightly rotten odours.

Mold can be grey, green, black, white, brown or orange and furry or raised.

For a full description go to the link on our resources page

What we know as Mold is actually a microscopic fungi. Its spores float freely through the air just like dust or pollen. Mold can grow on virtually any organic substance as long as warmth, oxygen and moisture are present. Mold germinates and begins to form when spores land or come in contact with a moist warm surface. Mold destroys or breaks down whatever medium it is growing on by gradually digesting the material. Molds grow readily on many materials commonly found in homes, including insulation, walls, windowsills, carpet, wood, furniture, paint, clothes, food and paper.

What is mold?

What types of mold should concern you and your family:

There are many types and varieties of mold. Some are benign (not harmful) as in Blue Cheese, some are even beneficial such as Penicillin, a chemical product of mold.

Outdoors, this process serves a necessary function by aiding in the decay of fallen timber, dead leaves, and other debris. The molds we are concerned about are the harmful kind from a mild irritant to down right toxic.
See our resources page for more sites and information

Condensation forms when enough moisture is carried in the air and touches a surface that has a lower temperature, such as a window, this temperature change causes the moisture in the air to turn to water or if the surface is cold enough, to ice. Condensation as it changes to water soaks into surrounding woodwork, window sills or wall coverings and combined with the warmth of the house, becomes a breeding ground for mold. When this occurs, a musty smell may continually circulate in the heavy, moist, stagnant air.

These are typical symptoms of an airtight sick house and fixing any one of them does not necessarily cure the problem; you can mop up the water, wash off the mold if it has formed but this may just temporarily eliminate a symptom. To actually alleviate the problem or "cure the illness" you need to introduce fresh outside air; this can be as simple as opening a window like we do in late spring, early fall or summer if we have no air conditioning.

With this introduction of fresh air the symptoms will actually disappear by themselves. This solution is not always practical in extreme weather conditions such as cold winter months and mid summer if the house is air- conditioned. For these extreme weather conditions we need to have a more practical solution. It is possible to efficiently bring in just the right amount of fresh make up air needed for the indoor environment to be comfortable, symptom free and well oxygenated.

This can be accomplished with a "Plusaire®" residential ventilation system from Pure Air Plus that installs easily using a distribution system you already have, your furnace and it ductwork and functions automatically bringing in the exact amount of fresh air needed to make your indoor environment comfortable regardless of the type of activities and amount of people living in the house.

Interestingly the awareness of the health problems that can arise from living in an airtight house thathas condensation and stale heavy air is still relatively unknown to most people. Although we are all aware of the air pollution outside and the quality of our water, we have had little information to date about the danger in the condition of the air in our own homes.

Several studies are currently underway by both the Canadian and US environmental branches and links to these can be found on our resource page . In Canada there is a new organization called Healthy Indoors with an interactive discussion forum also available on the resource page. The state of California held the first North American Indoor Air Quality Symposium in 2000 and this is available on CD. Indoor air quality is finally receiving the attention it deserves and with it the recognition that many of the modern day symptoms people are complaining about may be caused in part by our own homes.

Mold, Mildew and Moisture
"What causes mold to form?"

ENERGY EFFICIENCY the catalyst...... CONDENSATION the precursor......

A house that is experiencing excessive condensation has the potential of becoming a breeding ground for molds. There are many thousands of types of molds, none of them desirable and all of them are preventable.

All that is necessary for mold to form is moisture and warmth. The stale heavy air in an energy efficient airtight house provides enough excess humidity and moisture for condensation to form and creates an ideal environment for mold to grow. Newer houses that are well insulated such as an R 2000 or now available the R 3000 houses can show symptoms almost immediately if the initial occupancy occurs during the heating season. Symptoms of the lack of fresh air can appear as condensation, forming on the windows, sills and sometimes even on the walls. Another symptom is a heavy stale air feeling caused from humidity and the lack of oxygen some people may even feel as if breathing is difficult.
