Is Your Landlord Ignoring Your Mold Concerns?

Air Matters LLC has received a large number of calls in recent months from tenants who are concerned about mold testing and indoor air quality. These tenants have occupied a variety of properties from large apartment complexes or commercial office buildings to privately owned townhouses or duplexes. However, they have all shared one concern: “How can I get my landlord to take my complaint seriously and address this mold issue?”

In most cases, property owners or management are quick to deal with a valid mold situation. It minimizes property damage, keeps tenants healthy and happy, and is simply the right thing to do. Taking care of mold promptly also minimizes liability -- Across the country, renters have been awarded millions of dollars in lawsuits that contend significant health problems associated with exposure to mold.

But what should tenants do if they are having trouble getting a commitment to complete repairs and do any necessary remediation? Currently, there is no Federal law that sets permissible exposure limits or tolerance standards related to mold. Several states (including CA, TX, NJ, and MD) have passed some laws designed to establish guidelines for safe levels of mold in the air.

In North Carolina, mold is often addressed through the state’s Landlord and Tenant law – Chapter 42, which imposes minimum generic maintenance obligations for rental properties. This includes the obligation to maintain "in safe and good working order" many common sources of water and moisture intrusion that support fungal growth, such as plumbing and HVAC systems.

If you are a tenant with a suspected mold issue, notify your landlord in writing immediately. Include the date(s) you first noticed any conditions that might be associated with the problem, such as leaks or musty smells and a description of the progression of the problem. Take photographs to document the conditions, if possible. Include any supporting documentation, such as proof of medical appointments to address health symptoms you feel could be related to mold exposure. Ask when you can expect the problem to be addressed and follow-up.

If you are still unable to make any progress with your landlord, you may wish to consult with a mold professional, who can provide you with scientific data and environmental testing results to confirm, quantify and document your fungal exposure.

Flood Damage Leads to Mold Problems

Last week, a large portion of North Carolina experienced record-setting rain falls. Many areas in Eastern NC experienced flooding, including the town of Windsor in Bertie county, where homes and businesses contained several feet of water.

Federal Emergency Management Association (FEMA) crews visited the town of Windsor earlier this week, and the mayor is hoping for a federal disaster declaration. That declaration would provide federal funding and manpower to help the citizens clean up and get back on their feet from the largest disaster since Hurricane Floyd, which hit in September of 1999.

"Everybody is just going through the same routine," says Ted Shaw, a business owner in Windsor. "Got all the carpet up and out on the street. Sunday we came in and bleached and took the garden hose and washed all the water out to the street," says Shaw.

Are Ted Shaw and other residents of Windsor doing the right thing during their clean up?

The Environmental Protection Agency (EPA) has a publication titled "Flood Clean Up and the Air in Your Home" designed to help home and business owners prevent indoor air quality problems associated with flooding and flood water contamination.

This is a simple booklet that outlines steps for cleaning up safely after a flood, including use of the proper personal protective equipment. It also provides a list of resources where you can find additional fact-based information on flooding, clean up, mold and other related issues.

You can access a copy of the publication at http://www.epa.gov/iaq/flood/flood_booklet_en.pdf

Celebrities Sue Over Mold Issues

Ed McMahon filed the first memorable celebrity mold lawsuit back in 2002, claiming that faulty work to clean and repair his home after a pipe burst resulted in toxic mold that made him and his wife sick and killed their dog. He asked for $20 million in damages and settled the claim the following year for just over $7 million.

Other celebrities have sued their insurance companies, home inspectors, contractors and tradesmen over the years related to mold issues including Erin Brockavich, Lou Ferrigno, Michael Jordan, and Bianca Jagger. A few months ago, there were rumours that mold contributed to the deaths of Brittany Murphy and Simon Monjack, after they both died weeks apart and were found to have had similar pneumonia type symptoms.

Now, Rachael Ray and her lawyer husband John Cusimano have filed a lawsuit against two home inspection companies for failing to discover that the Southampton home they purchased in 2007 had water damage and mold growth. Rachel has suffered with respiratory problems repeatedly and feels that the mold either caused or at least exacerbated these symptoms, which impacted her effectiveness on camera and in front of her audience. Rachael and her husband have moved into her apartment in New York City until the situation is resolved.

Are home inspectors liable for positively identifying mold?
According to leading trade associations for the home inspection industry, NO!

The International Association of Certified Home Inspectors document "International Standards of Practice for Inspecting Residential Properties", reads as follows:

3. Limitations, Exceptions & Exclusions
3.2. Exclusions:
I. The inspectors are not required to determine:
J. the presence of mold, mildew or fungus.
K. the presence of air-borne hazards.

Likewise, the American Society of Home Inspectors document "Standards of Practice" states:

13.2 General exclusions:
A.Inspectors are not required to determine:
11.the presence of potentially hazardous plants or animals including, but not limited to wood destroying organisms or diseases harmful to humans including molds or mold-like substances.
12.the presence of any environmental hazards including, but not limited to toxins, carcinogens, noise, and contaminants in soil, water, and air.

Although many home inspectors do offer mold investigation and mold testing services, this is an additional area of expertise that requires specific training and often separate liability insurance coverage.

Your best bet when buying a home is to have an independent comprehensive home inspection in conjunction with a mold inspection. These two professionals working together can minimize your potential for buying a home with water damage and mold growth.

Football Frenzy Over MRSA Staph

Former Cleveland Browns center LeCharles Bentley sued the team last month over a career-ending MRSA staph infection he says he contracted at the team's training facility. Bentley's attorney, Shannon Polk, said Bentley nearly died from the infection while he was rehabbing from a knee injury.

"They told him their facility was the best," Polk said. "But they never told him about a host of unsanitary conditions there. And they never told him about the list of others who contracted staph before he chose to rehab there."

Bentley's knee became swollen, and he was diagnosed with MRSA staph infection shortly after beginning rehabilitation at the facility in July 2006, according to the lawsuit. The Browns had at least six players stricken with some sort of staph infection in recent years, including former receiver Joe Jurevicius, who settled a similar lawsuit with the team in June of this year.

What is MRSA?

According to the Centers for Disease Control (CDC) Methicillin-resistant Staphylococcus Aureus (MRSA) is a type of staph bacteria that is resistant to certain antibiotics called beta-lactams. These antibiotics include methicillin and other more common antibiotics such as oxacillin, penicillin, and amoxicillin.

How is MRSA Spread?

The CDC states that MRSA infections, as with all staph, are usually spread by having contact with someone’s skin infection or personal items they have used, like towels, bandages, or razors that touched their infected skin. MRSA is not thought to be spread through the air or associated with poor indoor air quality, although poor IAQ can cause other risk factors for infection.

What Can Athletes Do to Prevent MRSA?

The CDC offers the following prevention steps for football players as well as other athletes - including the high school player and the gym rat:

1. Practice good personal hygiene

•Keep your hands clean by washing frequently with soap and water or using an alcohol-based hand rub. At a minimum, hands should be cleaned before and after playing sports and activities such as using shared weight-training equipment, when caring for wounds including changing bandages, and after using the toilet.
•Shower immediately after exercise and do not share bar soap or towels.
•Wash your uniform and clothing after each use. Follow the clothing label's instructions for washing and drying. Drying clothes completely in a dryer is preferred.

2. Take care of your skin

•Wear protective clothing or gear designed to prevent skin abrasions or cuts.
•Cover skin abrasions and cuts with clean dry bandages or other dressings recommended by your team’s healthcare provider (e.g., athletic trainer, team doctor) until healed. Follow your healthcare provider’s instructions for when and how often to change your bandages and dressings.

3. Do not share items that come into contact with your skin

•Avoid sharing personal items such as towels and razors that contact your bare skin.
•Do not share ointments that are applied by placing your hands into an open container.
•Use a barrier (such as clothing or a towel) between your skin and shared equipment like weight-training, sauna, and steam-room benches.

Putting Your Carpet to Work

It’s used to getting walked all over, but now your carpet may be willing to do even more for you. Netherlands carpet manufacturer DESSO has introduced a new type of carpet specially developed to improve the air quality inside buildings.

The new type of carpet, called AirMaster, is eight times more effective in trapping particulate matter than hard floors and four times more effective than a standard carpet, thus greatly reducing the particulates breathed by building occupants. This was the conclusion of a study conducted by the independent German testing institute GUI.

This makes DESSO the world's only manufacturer to offer a product certified with the GUI's golden logo, which means that the carpet is 80% more effective than hard floors when it comes to trapping particulate matter.

The new Airmaster carpet from DESSO is primarily aimed at offices, hospitals, schools and other public buildings. DESSO if guaranteeing that AirMaster provides a significant improvement of the indoor climate and reduction in the risk of health-related problems.

Now if it could only vacuum itself. . .

MiST™ My Ride?

While I was waiting for my new tires to be installed the other day, a brochure on the counter caught my eye. . .

"A tidy car isn't free of mold, germ, and bacteria. A MiST™ Service is like a hand sanitizer for the vents & interior surfaces of your car. Get a MiST™ Service Today! You owe it to yourself and your family." Intrigued, I turned it over.

There was a magnified picture of a cultured sample taken from the interior of a Porshe, along with an illustration of streams of things coming from your car vent. Below these in bold print it said "Every time the fan is turned on, harmful spores are blown into the air you and your passengers breathe."

According to the EPA, some service providers may attempt to convince you that your air ducts are contaminated by demonstrating that the microorganisms found grow on a settling plate (i.e., petri dish). This is inappropriate. Some microorganisms are always present in the air, and some growth on a settling plate is normal. As for the "harmful spores" statement, only an expert can positively identify a substance as biological growth and lab analysis is normally required for final confirmation.

Upon visiting the company's website, you learn that "MiST™ utilizes atomized micro-droplets (1/10 the size of aerosol droplets) of a specially formulated solution. These droplets are drawn into an automobile's vents, penetrating and traveling to where the micro-organisms are living. MiST™ treats the entire ventilation system, including the evaporator, heater core, air ducts and passenger compartment surfaces." The company suggests that you perform this service every 6 months.

It does not say if the specially formulated solution includes water. If so, introducing this additional moisture into the system may actually promote fungal growth. Also, the EPA cautions about the use of biocides inside air ducts. They say that simply spraying or otherwise introducing these materials into the operating duct system may cause much of the material to be transported through the system and released. Depending on the product used, it may actually be more dangerous to breathe.

The company does suggest regular cleaning of your vehicle and maintenance of your filter system, both of which are important to minimize irritating contaminants.

Although this EPA document focuses on the air ducts in your home, many of the issues are the same. Read what they say at: http://www.epa.gov/iaq/pubs/airduct.html, and then decide if you want to MiST™ your ride!

Follow the Yellow Brick Road

It is easy to follow the yellow brick road during spring in North Carolina -- and the yellow sidewalk, and the yellow cars, . . .

Thick yellow pine pollen is everywhere, and allergy sufferers are quick to blame the pollen for their symptoms. However, as bad as it looks, pine pollen is not the main culprit.

The types of pollen that most commonly cause allergic reactions are actually produced by trees, grasses or weeds that do not have large, showy flowers or leaves. These plants have small, light dry pollen grains that are easily transported by the wind and inhaled by people through the nose or throat.

Ragweed, not pine trees, is the major culprit when it comes to allergic reactions. A single ragweed plant can generate up to one million pollen spores of pollen in a single day. Ragweed pollen is also extremely lightweight and travels through the air easily. In fact, scientists have collected samples of ragweed pollen 400 miles out at sea and two miles up in the air!

In contrast, pine pollen grains are much larger and fairly heavy. This is why they settle onto surfaces so easily. Stronger winds are required to keep pine pollen airborne for significant distances. Also, the types of allergens in pine pollen are less allergenic to most people as compared to the pollens found in many weeds or grasses.

The American College of Allergy, Asthma and Immunology offers these tips to help prevent allergy symptoms from kicking into high gear this spring:

•Don't assume you know exactly what you are allergic to. More than two-thirds of people who think their allergies only occur during the spring season actually have year-round allergies. An allergist can pinpoint the source of your allergic reaction and recommend the right treatment.
•Don't buy over-the-counter medications that don't alleviate allergy symptoms. Consult an allergist to determine which treatment options are best for you. Immunotherapy using nasal spray or shots may even cure allergies permanently.
•Don't wait until symptoms start to take allergy medications. Before the spring allergy season starts, begin taking a medication that's worked for you in the past.
•Take steps to avoid allergy triggers. Experts suggest that if you are allergic to pollen, keep your windows closed, take a shower after being outside and avoid going out in the middle of the day when pollen counts are highest.
•If raw or fresh fruits or other foods aggravate your allergy symptoms -- making you sniffle and sneeze and your mouth, lips and throat get itchy -- you may have oral allergy syndrome. This condition affects about one-third of seasonal allergy sufferers. While cooking or peeling these foods may help, it is wise to consult an allergist.

The Most Frightening Fungus?

Type "Black Mold" into an internet search engine, and what do you get? Links to over 5.5 Million pieces of information in less than a quarter of a second.

WOW! The majority of these sites refer to Stachybotrys. It is commonly nicknamed “stachy” and has been sensationalized as "black mold" or "toxic mold" by the media.

What is Stachybotrys?

Stachybotrys Chartarum is the single best known species of the genus. Despite the "black mold" nickname, Stachybotrys is not truly black, but is normally greenish-black in color. It tends to be somewhat slimy, as opposed to powdery. It thrives on on cellulose-containing products that have been wet for several days or more and enjoys a fairly constant moisture source.

Why are People so Worried About Stachybotrys?

Stachbotrys is known to produce trichothecene mycotoxins. Mycotoxins may enter the human body through ingestion, inhalation, or absorption through the skin. Exposure to these mycotoxins may have potential health effects for some individuals including coughing, wheezing, runny nose, irritated eyes or throat, skin rashes, and diarrhea.


Since these symptoms are general in nature, they also can be caused by a cold, virus or exposure to other allergens. It is not known what level of mycotoxin from Stachybotrys must be present in the air to cause health effect symptoms.

People with allergies may be more sensitive to Stachybotrys, as well as other molds. People with immune suppression or underlying lung disease are more susceptible to fungal infections that may be associated with mycotoxins.

Is the Concern About Stachybotrys New?

The potential effects of Stachybotrys toxins were first observed in cattle and horses in Russia in 1920. Stomatitis, rhinitis, conjunctivitis, pancytopenia and neurological disorders developed in these animals after they ingested hay contaminated with Stachybotrys.


Later in the 1970s, it was claimed that Yellow Rain attacks in Southeast Asia were associated with the use of aerosolized trichothecenes as an agent of biologic warfare. However, this claim remained scientifically unproven.

What Caused the More Recent Focus on Stachybotrys?

In 1994, the U.S. Centers for Disease Control and Prevention (CDC) investigated whether exposure to Stachybotrys might be related to pulmonary hemorrhage, also known as bleeding lungs, in infants in Cleveland, Ohio.


While the CDC initially concluded that there was a possible link between exposure to the mold and the condition, Stachybotrys was not found in the homes of seven children with bleeding lungs identified in the Chicago area between April 1992 and January 1995.

A subsequent review of the Cleveland study by a group of CDC experts concluded that a link between exposure to Stachybotrys and bleeding lungs in infants was not proven.

Where Can I Get More Information?

If you want additional information on Stachybotrys, make sure you are using reputable sources that provide the facts rather than relying on scare tactics.


Several good places to start include the Environmental Protection Agency (www.epa.gov/mold) and the Centers for Disease Control (www.cdc.gov/MOLD/stachy.htm).

What You Should Know About Air Sampling for Mold

What is Air Sampling?

Air samples are one of the common techniques used to test for mold. This method quantifies the exposure levels associated with an indoor space and typically compares that level to an outdoor baseline.

Air Matters LLC uses spore trap samples for its air sampling services, specifically the AIR-O-CELL air sampling cassette. This device is designed for the rapid collection and analysis of a range of airborne bioaerosols including fungal species, pollen, skin cell fragments, and insect parts.


How Does Air Sampling Work?

A high volume air pump is calibrated prior to the start of the sample. The AIR-O-CELL cassette is labeled and attached to a tube at the end of the pump. The pump pulls the particulate laden air through the cassette, and the air flow continues out an exit orifice. The length of the sampling period is digitally timed to ensure accurate calculation of the air flow.

The particles are deposited on an adhesive area contained inside the cassette. The AIR-O-CELL cassette is removed from the tubing and sealed. The specific information regarding the sample is recorded on a chain of custody form. After the assessment, all samples and the chain of custody are transported to the laboratory for analysis.

At the lab, the cassette is opened and examined under a microscope. The various particles are identified and quantified. This information is summarized in a report and transmitted to Air Matters LLC.


What Does Air Sampling Tell You?

It is important to remember that air sampling data provides a snapshot of one specific moment in time. Conditions change constantly based on such factors as temperature, HVAC operation, relative humidity, or building activities.

Since there are no widely accepted numerical guidelines regarding mold like there are for other contaminants (radon for example), a thorough site assessment by a qualified professional is critical to interpreting laboratory findings.

If you have more specific questions about air sampling, give us a call today!

Does Mold Have You Acting Like a Witch?

Mold really can make you act like a witch. . .

I recently came across some information on a book called Poisons of the Past: Molds, Epidemics, and History. In this story published twenty years ago by Yale University, history professor Mary Kilbourne Matossian presents a large amount of evidence that the population of Europe was held down for 500 years by endemic mold-induced food poisoning called ergot or ergotism.

Although most sources attribute this long epidemic to fungi in the genus Claviceps, she also gives credit to the genus Fusarium. Both genera infected rye kernels before and after harvest, producing toxic, long-acting alkaloids (e.g., ergotamine).

Professor Matossian's preface of her book starts off with "People make history, but not just as they please. However strong and intelligent they may be, human beings are vulnerable creatures. . . They may even be laid low by organisms too small to be seen by the naked eye."

She goes on to explain how the poor in northern Europe, who lived on rye bread and little else, were the most affected by molds and the mycotoxins they produced. Grains were truly considered the staff of life, and the poor ate 2-3 pounds of it per day.

Wealthy households were never affected as much as poor households, because their servants prepared the grain as gruel, boiling it over a fire for about a half hour, which broke down the toxin. They also enjoyed a more diverse diet, including meat and white bread.

Poor women miscarried and children died frequently. Those who survived childhood had chronic illnesses, gangrene, and mental disturbances. The hallucinations and seizures experienced were often interpreted as witchcraft, possession, or divine inspiration. Neither the people affected or those around them could explain the uncontrolled behaviors.

No one knew that their diet was responsible for their misfortune. Not until wheat and potatoes began to replace rye did the epidemic abate.

There is even a section on how ergotism may have played a significant role in the Salem Witch Trials. The early settlers of Massachusetts planted rye, ate rye bread, and experienced hallucinations and seizures that are documented to be just like those of the Europeans.

Further discussion examines the growing season, winter and summer temperatures, soil composition, and drainage in the Salem area as likely to contribute to a rye crop infected with ergot.

For more information on the book, including the complete table of contents and an extended preview of many pages, check out Poisons of the Past: Molds, Epidemics, and History on Google Books.

Now you will have to blame those moods on something else!

EPA Teams with Building Industry Experts on Comprehensive IAQ Guide

Too often, indoor air quality (IAQ) problems result from poor planning, improper design, or inadequate construction methods and materials. If design and construction teams work together to incorporate good IAQ strategies from the start, many of the common pitfalls can be avoided.

The Indoor Air Quality Guide: Best Practices for Design, Construction and Commissioning is a collaboration between the American Society of Refrigerating, Heating and Air Conditioning Engineers (ASHRAE), the American Institute of Architects, the Building Owners and Managers Association International, the United States Environmental Protection Agency (EPA), the Sheet Metal and Air Conditioning Contractors of North America, and the United States Green Building Council, which awards the internationally recognized LEED green building certification system.

The book outlines specific strategies for achieving eight critical IAQ objectives relative to moisture management, ventilation, filtration and cleaning, and source control.

A 198-page summary of the guide can be downloaded free of charge at www.ashrae.org/iaq. The full publication, including a CD, is also available through ASHRAE for $29.

Within the summary, Objective 2 - Control Moisture in Building Assemblies and Objective 4 - Control Moisture and Contaminants Related to Mechanical Systems offer strategies to limit water and moisture intrusion, which directly impact the growth of fungal (mold) species.

The summary guide states in Objective 2 that "Moisture in buildings is a major contributor to mold growth and the poor IAQ that can result. Wetting of building walls and rainwater leaks are major causes of water infiltration."

There is also significant attention in this section given to controlling indoor humidity levels. High humidity supports the growth of mold, dust mite populations, and other biological contaminants indoors that may cause allergies or other health problems for building occupants.

Low humidity levels can dry out mucous membranes. Either way, "humidity conditions also affect people's perceptions of the IAQ."

Objective 4 starts out explaining the important role of mechanical systems in providing good IAQ. It then states "However, since many mechanical systems carry water or become wet during operation, they can also amplify and distribute microbial contaminants." Detailed strategies are discussed for each component of the mechanical systems.

Considering IAQ from the initial design process through the building occupancy will ensure that everyone breathes a little easier.

Should the Dust Mites in Your Mattress Scare You?

You have heard the radio commercials with the statistics. You have seen the ads with the pictures (which look pretty scary when magnified 5,000 times!). Oprah has done a special episode on it. Even the Wall Street Journal has published articles in the past saying that "the average mattress will double its weight in ten years due to an accumulation of dust mites and their feces."

The thought of crawling into bed with pounds and pounds of dust mites and their feces gives you nightmares, not a restful night's sleep. Next you calculate the age of your mattress, and now you are truly frightened. The next day, you immediately begin your quest for new bedding.

A great marketing ploy, but do these claims have any scientific basis? Here are what a few experts in the field of dust mites had to say to Cecil Adams, who writes a syndicated weekly newspaper column called "The Straight Dope":

"It's nonsense," said mite authority Larry Arlian, professor of biological sciences, microbiology, and immunology at Wright State University. "I don't know where that originated. They're not that prolific."

Thomas Platts-Mills, professor of medicine and dust-mite guru at the University of Virginia, agreed. "I've heard that kind of stuff," he said. "I don't believe it. I'm sure there's an added weight but I don't think anyone has ever actually measured it."

Emmett Glass is the Ohio State University research associate leading the "Dust Mite Management Study" He was the gentleman that Wall Street Journal reporter said was the source of the claim that a mattress will double its weight due to dust mites. Emmett writes:

"I never quoted that statistic. I told [the reporter] that Internet web sites have statistics that try to strike fear in the consumer, thus promoting their products. I gave her a few off the top of my head (two million mites in an average mattress, mattress doubling in weight, etc.) that I read over the years. She asked me if any of these statistics have any scientific merit and I told her that none of them are in the literature. To the layman that is NO! In fact I asked the Wall Street Journal writer to call an expert on mattresses at the internal sleep products association. She did and was told that the statistic on mattresses doubling in weight was far from the truth. The journalist choose to include it in the story anyway. She liked the statistic because it made her story more interesting."

According to the American College of Asthma, Allergy & Immunology, only 10% of the general population is allergic to dust mites. However, 90% of people with allergic asthma are likely sensitive to dust mites and should take additional precautions.

Margot Carmichael Lester at the Museum of Life and Science in Durham offers the following tips to reduce your exposure to dust mites:

•Keep relative humidity low (under 55 percent) because dryness kills germs.
•Use a HEPA filter-equipped vacuum to keep allergens from releasing back into the air. Change the bags at least once a month.
•Switch out air filters according to manufacturers recommendations.
•Vacuum mattresses, carpets, upholstered furniture and window treatments at a very high setting.
•Toss stuffed animals, throw pillows and small rugs into the dryer on high heat regularly.
•Cover bed pillows, mattresses and box springs with impervious covers to keep dust mites from coming through.
•Unclutter rooms with most use (bedrooms, family rooms), including extra pillows and bed covers, out-of-season clothing, throw rugs, stuffed animals – and anything that gets (and stays) dusty.

You can use the money you save by not having to buy a new mattress to take your family over to Durham for a visit to the museum!

Who Knew Slime Molds Were So Smart?

If you have been in North Carolina in the summer time, you have seen it. The big yellow patch that appears on the mulch bed in your yard a couple of days after the rain. It looks like. . . well, dog vomit. Eeeeew!

This is slime mold, officially named Physarum polycephalum. However, slime mold is not truly a mold, as it is not classified as a fungi. Although slime molds may not be fungi, they are apparently smart. Check out this article from The New York Times:


Slime Mold Proves to be a Brainy Blob
THE NEW YORK TIMES

Let's hear it for slime molds. Researchers in Japan have shown that a slime mold can design a network that is as efficient as the Tokyo rail system. Furthermore, the slime mold can build its network in a day.

A slime mold is what scientists call a single-celled amoeboid organism. When foraging for food, it spreads out as an amorphous mass, then builds tubular connections between food sources. This is a smart blob.

"We've found an unexpected high ability of information processing in this organism," said Toshiyuki Nakagaki, a researcher at Hokkaido University. "I wanted to pose a complicated problem to this slime mold, to design a large network," Nakagaki said. "This kind of program is not so easy, even for humans."

So he and his colleagues set up an experiment where they laid out 36 bits of food in a pattern corresponding to cities in the Tokyo area and put a slime mold, Physarum polycephalum, at the spot corresponding to Tokyo.

As they report in Science, after 26 hours the slime mold had created a series of tubular connections that matched, to a great extent, the rail links among these cities. The researchers found that the slime mold network was as efficient as the rail network, it tolerated breaks in the connections just as well, and it was created at a reasonable cost to the organism.


26 hours and at a reasonable cost?? I think we have just identified the perfect contractor to design the Southeast High Speed Rail Corridor from Charlotte to Washington DC!

Are You Suffering from Sick Building Syndrome?

"Sick Building Syndrome" is a term that is used to describe when somebody experiences health or personal comfort effects that seem to be linked to the amount of time spent in a particular building, but they are unable to positively identify a specific cause or health condition responsible for these effects.

These effects may only be felt when in one particular room or area of a building, or they may be experienced throughout the facility. Also, they may be limited to one individual or can affect a large number of building occupants.

The complaints differ and can include many symptoms such as headaches; dry, itching, red or watery eyes; sensitivity to odors; coughing; dry or itchy patches or skin including rashes; dizziness; nausea; or fatigue.

Two things that do seem to be consistent with Sick Building Syndrome are the fact that an immediate cause of the symptoms is not known and that people who are suffering report a relief from these symptoms once they are away from the building.

According to the Environmental Protection Agency (EPA), the following factors are often responsible for causing or contributing to complaints of Sick Building Syndrome:

1. Biological Contaminants
This includes mold, mildew, bacteria, pollens, and insect or bird droppings. These contaminants may breed in stagnant water that has collected around building leaks or in ducts, drain pans, or humidifiers.

2. Indoor Chemical Contaminants
Adhesives, carpeting, upholstery (including fabric cubicle walls), manufactured wood products (particularly press board), copy machines, pesticides, cigarette smoke, and cleaning products may all emit volatile organic compounds (VOC's), including formaldehyde.

3. Outdoor Chemical Contaminants
The outdoor air that enters a building, particularly through poorly positioned air intake vents, doors or windows can also be a source of chemical pollution. Common contaminants may include motor vehicle exhausts, plumbing vents, kitchen fumes, or bathroom exhausts.

4. Inadequate Ventilation
Energy conservation measures and construction methods have resulted in buildings today being more tightly sealed than ever before. As a result, there has been a decrease in the outdoor air exchange. Inadequate ventilation may also occur when the HVAC system is not properly sized, balanced or maintained for the square footage and type of occupancy intended and is unable to effectively distribute conditioned air to the occupants of the building.

A professional indoor air quality investigation is one tool to help identify potential risk factors that may be contributing to symptoms of Sick Building Syndrome.

Resolve to Improve Your Indoor Air Quality in 2010!

So, we are a little half way through January. How are those New Year's resolutions going? Eating right, exercising more, getting enough sleep every night. . . you know these things are good for you. That doesn't make them easy. Breathing -- now that's easy. But what about monitoring what you are breathing into your body each day? That's a little tougher!

The toxins that you breathe in every day (air quality) often go unnoticed simply because they are invisible. Things that are invisible (unlike smoking cigarettes, really bad for you foods, and toxic friends) are easy to overlook. The Kingston Whig Standard offers these tips for improving your personal air quality today:

1. Quit smoking. Cigarette smoke contains known carcinogens (cancer-causing agents) and a host of chemicals. If you can't quit just yet, be sure to smoke outdoors. (NOTE: In North Carolina restaurants and bars, you have no choice but to smoke outdoors. Yeah!!)

2.Change furnace filters monthly. Reduce the dust and allergens in the air by changing your furnace or air conditioning system filters on a monthly basis. Also vacuum intake vents. You can consider having ductwork cleaned by a professional service, too. (NOTE: Air Matters LLC recommends you review the following document published by the Environmental Protection Agency prior to having your ducts cleaned. http://www.epa.gov/iaq/pubs/airduct.html)

3. Fill the house with plants. Plants naturally filter the air and give off fresh oxygen. Plus, they're nice to look at!

4. Avoid pressboard furniture. Many composite wood products contain formaldehyde and other chemicals. These can sneak into the air over time.

5. Use all-natural cleaners. Chemical-laden cleaners don't simply smell strongly, they can actually be very harmful if breathed in. Also, never mix cleaning products (such as bleach and ammonia). It can produce a toxic gas. Lemon juice, vinegar, baking soda, and other all-natural items can be used as very effective cleaners.

6. Vacuum carpets regularly. Carpets and fabrics can harbor dust and other allergens. Some newer carpets are created to reduce allergens, but most carpets should be cleaned two to three times a week, primarily in high-traffic areas and in homes with pets. (NOTE: Air Matters LLC recommends that you invest in a HEPA-vacuum.)

7. Eliminate leaks. Drippy faucets or a damp basement can lead to the growth of mold and mildew. While many types of these fungi are harmless, there are some that are very harmful if breathed in. If you have a mold or mildew problem, call in a professional for a threat assessment and advice on proper cleaning. (NOTE: If you want to confirm the presence and identity of fungal species, that would be Air Matters LLC. . .)

8. Test for hidden dangers. Radon, carbon monoxide, and asbestos could be lurking in your home. Testing eliminates threats and can safeguard your family.

9. Call in a cleaning crew. Regular cleaning can limit the amount of particles floating around in the air. Keeping the house spic-and-span is a way to clean the air as well. Having a regular cleaning service come in can be a way to fit a thorough cleaning into your busy schedule.

10. Dial down the humidity. Run the exhaust fans in bathrooms and invest in a dehumidifier. Mold and mildew, as well as dust mites, thrive in moist conditions.

11. Launder sheets and pillowcases every 10 days. Buy machine- washable pillows and bed linens.

12. Kick out pests. Allergens from roaches are a major cause of asthma, and airborne protein from dried rodent urine is a potent allergen.

13. Air it out. On low-particulate days, throw open the windows and let the fresh air in.

14. Check the venting. All appliances should be properly vented. Make sure vents are free of obstructions. Appliances should be serviced according to the manufacturer's maintenance schedule to avoid combustion byproduct buildup and reduce dust and particulate accumulation.

Resolve to improve the indoor air quality in your home, and you can breathe easier in 2010!

Check for Mold Before Buying Foreclosures

The American economy is still reeling from the recession, and the housing market remains one of the hardest hit areas. As foreclosures continue to mount, many of those who do have cash to spare are looking to invest in bargain real estate.

However, bargain hunters need to beware of potential unseen problems that could quickly drain their profits -- including hidden mold. Home owners who were foreclosed upon likely did not have the money to perform routine repairs and maintenance, which may have grown into larger problems. In addition, foreclosed properties may have been vacant for some time and many issues may have gone unnoticed.

RIS Media, a well-known source for news and information in the real estate industry, offers these 10 trouble spots to consider when purchasing a foreclosed home:

These 10 Signs May Indicate That Trouble is Around the Corner

1. Unheated house in winter months. If the home has been properly winterized, there's no need for heat. But if the home has not been properly winterized, pipes will burst and cause water damage.

2. Missing sinks, toilets and other fixtures. Make sure they've been properly removed and not ripped from walls and floors.

3. Peeling, bubbling, and discolored paint; swelling in walls or ceilings (especially around kitchens and bathrooms) or a musty odor all indicate water damage and, potentially the presence of moisture and mold.

4. Fungus growth inside cabinets, behind drawers and built-ins. Fungus could mean that there has been water damage. Since water falls down, look for a source above the mold.

5. Blocked drains or pipes will cause future problems and may have already created sewage backups.

6. Black cobwebs, greasy gray residue on walls and/or a strong oily odor. This could point to potential soot damage or a malfunctioning furnace.

7. An older home with extensive renovations. Check with the city for pulled permits in order to get remodeling details. If asbestos is present and has been disturbed, be sure it's been remediated by a certified specialist.

8. Excessive painting of every nook, cranny, door and floor may mean that the seller is covering up mold.

9. Discolored sub flooring. From the basement, check the sub flooring above for stains and small holes, both caused by mold.

10. Air Quality. The air quality within a home tells a lot about the home's condition. Be sure to include air an surface testing in your home inspection. It's a few hundred dollars well spent!
