MOISTURE, MOLD AND MILDEW By: Nick Martello, CIE, CMA There's an ever present (ongoing) debate over 'What are the Human Health Effects' as they relate to Mold and exposure to Mold? Allow me to share this vitally important point to begin. No two people are alike and no two people will experience the same effects from within the same indoor environment... at the same time! It is virtually impossible for two people to react or respond to the same mold specie and contamination the same way!
IS MOLD A PROBLEM?
What are insurance companies doing about mold? All I hear is; Mold isn't covered by insurance companies. Have you taken the time to review your "environmental clause" in your homeowners policy lately? Does it state or show that mold is covered? Probably not! The insurance industry has been completely broad-sided by the mold issue and they do not have an answer... except... to not provide coverage!
INSURANCE INDUSTRY
REAL ESTATE INDUSTRY Remember, if the mold problem is not fully remediated and the moisture problem completely repaired, the mold will positively reoccur! Mold can and will come back over and over as long as the moisture problem exists, even if painted, or washed or disinfected... it must be remediated completely and that includes the moisture infiltration problem! There was a time in the late 1990's and until just a couple of years ago, when a real estate agent would see the mold problem and immediately realize that if it isn't "removed," it will cost me a good portion (if not all) of my commission! So there was a tremendous amount of "odor masking" being done with candles, sprays and chemicals. There was a lot of painting or wall-papering or paneling over mold to "hide" it. Almost any method to cure the visible signs or odorous smells were taken to save the deal and save the commission. Until January 1, 2004, Ohio was a "Buyer Beware" State, meaning that it was 100% the buyers responsibility to check out all aspects of a home (inspections, engineering reports etc., before they would place a bid or purchase the property! So, if the mold smell was masked, or the moldy wall or ceiling was painted or covered, they wouldn't notice the mold until after they purchased the home... and by then, they owned it and the mold! January 1, 2004, the Ohio Department of Commerce changed the status of Buyer Beware to: Disclosure Law - Yes, Disclosure was mandatory or you could be held responsible and legally liable if proven that you knew you had a mold problem and didn't disclose it! You could and would have to pay or compensate for damages! Mold is present indoors and outdoors, and when you can smell it or it becomes visible, it must be dealt with! To deny it exists or to say it is unimportant... is wrong... and it can place you on the wrong side of a legal issue... you can become "legally liable" if you deny or fail to disclose a moisture problem or indoor environmental problem. Beware and be responsible. It's less costly to disclose as opposed to being sued! I've made it my responsibility to "Educate!" both homeowners and real estate personnel. But, if they choose to ignore the information, then they will have to pay the piper... because mold knowledge it readily available. The EPA has excellent information EPA-2, and so do the following; The Center for Disease Control, New York City Department of Health. These are just a few of the "Credible" sources that all should be looking at. Texas, Florida, California, Minnesota, New York and Connecticut are only the beginning. Mold is quickly becoming the #1 study of Indoor Air Quality today.
MEDICAL INDUSTRY Even today, we fully recognize that Asbestos has caused serious illnesses and health effects in many people. But, even asbestos (today) does not have a defined acceptable level of exposure, nor (in my opinion) will they be able to. The scientific and diagnostic uncertainties and concerns are virtually the same between asbestos and mold... because no two people are identical. In example; Two people are exposed to the identical mold for the exact same time period yet, both will produce unique results. Now multiply that times 6+ billion people living today... you can easily ascertain the virtual impossibility to establish reproducible scientific documentation that will satisfy the; legal, technological, economic, management and procedural aspects surrounding the mold issue.
SIMPLE FACT OF LIFE:
THE AIR WE BREATHE: The trachea consists of a supporting layer of connective and muscular tissue in which are embedded from 16 to 20 U-shaped rings of hard cartilage that encircle the front of the tube. Tiny hairs, or cilia, in the mucous membrane lining keep dust and other foreign particles from entering the lungs. The foreign material becomes trapped in the mucus and is swept by the beating cilia to the nose or mouth, where it is discharged from the body.
I always share with my clients, "If you can see or smell mold, then there's positively too much present and it must be removed!" This is also how and why spores can easily move through and around our nasal hairs (almost uninterrupted) and down and through our windpipe and finally rest inside our lungs (Our 'Breathing' Center). It's not a favorable situation. It is the quantity and type of mold spores that travel into our body, and for how long, that is the important medical and scientific issue.
WHAT ARE THE RIGHT
CONDITIONS FOR MOLD TO GROW?
So now we are only missing the third requirement...
Remember that heat and food are always present... it's the moisture that we can and must control in order to stop the mold growth. Stop the Moisture...Stop the Mold!
CAN MOLD CAUSE HEALTH
PROBLEMS?
IN SUMMARY: If you can see mold, you have too much! If you can smell stale or musty indoor air... you probably have mold and you should get a professional in to test it. Before you go about scrubbing it off with bleach or biocides... it is highly recommended that you know "what" kind of mold you actually have and in "what" quantity. This will tell you if you have a pathogenic or toxigenic type of mold present. Believe me, the difference will matter... if medical conditions or litigation is involved. For the cost of a normal evening out for a family of four, dinner, drinks and theater, you can have a good Indoor Air Quality Inspection. How long will people keep placing their health issues in the rear? How many people wait until it becomes a far too serious issue? Why are people so willing to tolerate being uncomfortable? Isn't it time we look at our QUALITY OF LIFE instead of the "how much can I tolerate and put up with?" Start looking out for #1 (YOU). Start looking out for your family! Start looking out for your employees! Start looking out for Health and Safety Issues in your Home or Place of Work!
Acremonium This mold is commonly found in soil and on dead plant material. Indoors it grows on wet building materials like drywall ceiling tiles and building paper. Acremonium should be considered allergenic and may be a pathogen for immunocompromised individuals. Alternaria Commonly found in outdoor air, on many kinds of plants and foodstuffs and prefers rotting farmland manure. It may be resistant to fungicides. Alternaria is considered an occasional contaminant of water damaged building materials which contain cellulose. Although Alternaria is a notable source of fungal allergy, pathogenic infections are also reported infrequently. Aspergillus There are a wide variety of species of Aspergillus. Some are considered opportunistic pathogens and may cause pulmonary infections. Some members also produce mycotoxins and have been implicated in causing allergic reactions and hypersensitivity pneumonitis. Aspergillus type organisms are some of the first fungi to grow on water-damaged materials and are frequently found in water-damaged structures. Although they are commonly found in the outdoor environment, the outdoor frequency is generally considered low. Aureobasidium This yeast-like fungus is commonly found on caulk or damp window frames in bathrooms. Aureobasidium may be pink or black in color. Although it seldom causes infections, it can be allergenic. This is one type of mold that is a type of mildew. It will grow in cooler climates and along with Cladosporium is commonly found growing on siding. Bacillus Survives in soil. A gram positive rod which is part of a large family of organisms which are for the most part non-pathogenic for man. Basidiospores Frequently associated with dry rot, Basidiomycetes are primarily mushrooms, toadstools, puffballs, rusts and smuts. High levels of these spores can contribute to allergies in indoor environments. Poria incrassata is a particularly destructive fungal organism that falls into this classification. Poria has resulted in the collapse of severely infested buildings. Botrytis Most commonly associated with plants, Botrytis can cause allergic asthma after indoor exposure. High levels are likely to be found in greenhouses or other indoor areas with high humidity and large numbers of plants. Ceratocystis / Ophiostoma This is a very common plant pathogen that is frequently found on lumber in lumberyards and is built into most homes. It has not been well studied and has not been reported to be pathogenic or a producer of mycotoxins or allergens. Chaetomium Commonly found on deteriorating wood products, Chaetomium frequently emits a musty odor and is frequently found on water-damaged drywall. Its health effects have not been well studied, however some rare compounds have on occasion been identified as mutagenic. Cladosporium Cladosporium is the genera most frequently encountered in both outdoor and indoor air. It is frequently found in elevated levels in water-damaged environments. Some species may be resistant to certain types of treated lumber. Epicoccum A secondary invader of plant materials, Epicoccum can grow at higher temperatures than many fungi, allowing it to be a human skin pathogen. Colonies produce a wide variety of colors depending on the food source. Although it may be isolated from water damaged building materials, it is generally thought of as a typical outdoor organism. Fusarium Found in soils and on plants worldwide, Fusarium can invade corn and barley and produce toxins at lower temperatures than many fungi. Fusarium has affected water-damaged carpets and a variety of other building materials, and can cause infection in immunocompromised individuals. Its spores are typically slimy and may be difficult to isolated from air samples. It has also been implicated in exacerbation of allergies and asthma and may produce mycotoxins. Gram Negative Rods Group of bacteria commonly found in standing water or water saturated structures. Most are opportunistic pathogens. Many species release endotoxins that can cause headaches and allergic type reactions. Mucor This mold is found worldwide and is frequently present in air samples. Mucor commonly grows on dung and moist hay. It is fast growing opportunistic and may cause rare infection in immunocompromised individuals. It is considered a mild allergen. Penicillium Penicillium species are common contaminants on various substances. This organism causes food spoilage, colonizes leather objects and is an indicator organism for dampness indoors. Some species are known to produce mycotoxins. The health of occupants may be adversely affected in an environment that has an amplification of Penicillium. Penicillium is one of the first fungi to grow on water-damaged materials and has been implicated in causing allergic reactions and hypersensitivity pneumonitis. It commonly produces a strong musty odor. Pithomyces Found in decaying wood, soil, and plant material, Pithomyces is not known to cause infections or major health problems in humans. It has been found growing on paper but is not commonly found growing indoors. Rhizopus Frequently found in house dust, soil, fruits, nuts, and seeds, Rhizopus often grows in fruit and vegetable garbage, or in forgotten leftover food. Exposure to large numbers of Rhizopus spores has reportedly caused respiratory complications. Rhizopus can be an allergen and opportunistic pathogen for immunocompromised individuals, especially those with diabetic ketoacidosis, malnutrition, or severe burns. Scopulariopsis A common contaminant that can cause toenail infections. Sepedomium A common soil contaminant. Non-pathogenic to humans. Stachybotrys chartarum Stachybotrys grows well on extremely wet building materials containing cellulose that have remained wet for more than a week. It produces mycotoxins that can irritate skin and mucous membranes. One potent mycotoxin produced by Stachybotrys is called satratoxin; it is also toxic when inhaled. Extreme care should be taken when this organism is amplified indoors. Sterile Mycellium Fungi that are not mature enough for speciation. Streptomyces Generally non-pathogenic. Some species can cause infections in humans. Also produces potentially harmful mycotoxins. Odor characteristic of freshly tilled soil. Important in the pharmaceutical industry. Trichoderma One of the most widespread soil fungi, Trichoderma grows in carpet, on unglazed ceramics, and on paper in damp homes. Some species produce metabolites related to trichothecenes, which can be toxic and may cause symptoms like those associated with Stachybotrys chartarum. It is also an allergen and may infect immunocompromised individuals. Ulocladium Isolated from soil, wood, and decaying plant material, Ulocladium grows on very wet walls and particleboard. Because of its high water requirements it is considered an excellent indicator of water damage. This genera is allergenic, contributing to the allergy load especially in those with Alternaria allergy. Wallemia Found worldwide in house dust, air samples, dry foodstuffs and soil. Wallemia attacks materials with low water activity, is an allergen and may produce mycotoxins. It is known to grow on materials with high salt content. Yeast Common in moist habitats and often able to grow at reduced oxygen levels. This organism can cause allergies and can be an opportunistic pathogen.
