What Is The Worst Kind Of Mold

There Are Many Types Of Dangerous Mold

Types of Mold

One of the dangers of buying a home with mold is that there are so many different kinds some of which can be extremely toxic. Researchers have identified over 100,000 different varieties of mold, many of which are routinely found indoors.

Someone who is unfamiliar with mold might be unable to recognize the signs, even if they were to see them. Further, mold often grows in hidden spots you cant easily get to, like underneath carpets or in the attic.

Mold growth is often missed by traditional home inspectors as well unless there are obvious physical signs. This means they will not be able to identify all the problem areas properly, so you could wind up buying a home with severe mold issues. To avoid this issue, it is highly recommended to schedule a professional mold inspection before buying.

Association Of Stachybotrys Species With Sick Buildings

One of the best studies of building-related illness showed minimal relation to Stachybotrys. Miller et al. examined 50 Canadian homes in which the occupants had complaints of respiratory or allergic symptoms for which there was no explanation, although at the time of the study, occupants of only 6 houses had building-related illnesses. Looking at air exchange rate, moisture levels, and analyzing air and dust for fungus and fungal products in 37 of the homes, they found S. chartarum in only one house analysis of the 6 sick houses did not indicate fungus-related disease. During parts of the year when windows are open, indoor fungi are comparable to outdoor species . However, in this study, outdoor air spores were negligible and Penicillium and other soil fungi were most important. Toxigenic fungi included P. viridicatum, Trichoderma viride, P. decumbens, and A. versicolor. House dust usually contained appreciable amounts of filamentous fungi and yeast, and so it was expected that spores could be found in air, depending on the activity in the room.

How Do Molds Affect People

Exposure to damp and moldy environments may cause a variety of health effects, or none at all. Some people are sensitive to molds. For these people, exposure to molds can lead to symptoms such as stuffy nose, wheezing, and red or itchy eyes, or skin. Some people, such as those with allergies to molds or with asthma, may have more intense reactions. Severe reactions may occur among workers exposed to large amounts of molds in occupational settings, such as farmers working around moldy hay. Severe reactions may include fever and shortness of breath.

In 2004 the Institute of Medicine found there was sufficient evidence to link indoor exposure to mold with upper respiratory tract symptoms, cough, and wheeze in otherwise healthy people with asthma symptoms in people with asthma and with hypersensitivity pneumonitis in individuals susceptible to that immune-mediated condition.

In 2009, the World Health Organization issued additional guidance, the WHO Guidelines for Indoor Air Quality: Dampness and Mould pdf iconexternal icon pdf icon. Other recent studies have suggested a potential link of early mold exposure to development of asthma in some children, particularly among children who may be genetically susceptible to asthma development, and that selected interventions that improve housing conditions can reduce morbidity from asthma and respiratory allergies.

Fungal Organisms In Damp Buildings

A host of mold species have been isolated from damp buildings: the most frequently isolated in one study were Penicillium , Cladosporium , Ulocladium , Geomyces pannorum , and Sistronema brinkmannii . There were 66 species of filamentous fungi, and yeasts were found in 94% of dwellings and 13% of CFU on Anderson sampler plates. In contrast to the aforementioned species, Stachybotrys was less common, being found in 12.8% of dwellings and 4.5% of samples. Other studies have reported similar organism frequencies 1) . In most studies, Stachybotrys has had a low prevalence, being present in less than 3% of samples . However, some recent work has suggested that it may be more common than was initially thought . Regardless, Stachybotrys is rarely found in isolation, nearly always occurring in the presence of other fungi . This fact is critical, since many of the other species are capable of producing mycotoxins , and recent work suggests that volatiles from S. chartarum may represent a small fraction of the total amount present in problem buildings where other fungi exist .

Mold Type Number Two: Chaetomium

So in reality, our home already has 2 out of 3 of these requirements. This means it only needs one thing to grow moisture.

There are spores present in the air. They will land on surfaces. Nothing happens if that surface is dry. But if theres moisture , its now the perfect environment for it to grow.

Why is there moisture in our home? It can be because of any of the following:

Moldy homes are a major problem in the United States as it is present in nearly every building in the country. The reason that mold is so prolific is because it only takes 24 to 48 hours for mold to grow in a moist indoor area. It also grows well in dark, damp spaces, so its often found in kitchen cabinets, bathrooms, basements, and crawlspaces.

Now, not all mold is worrisome. And since virtually every home has trace amounts of mold growing, its nearly impossible to avoid buying a mold-free house. But there are some significant dangers to buying a house with mold growth.
