Mold Types, Identification & Effects on Humans

UNDERSTANDING MOLD

Understanding mold, how it forms, and the factors contributing to its development is one of the best ways to prevent it from forming in your home or office. Molds are a diverse group of organisms that can be extremely toxic, or equally beneficial to humans in some cases.

The Good - Beneficial Molds

Mold, although generally considered a nuisance or hazard by most of us, plays an important role in our environment. What we commonly refer to as molds are generally a type of fungi with a couple exceptions (more on that later). These organisms are important because without them the formation of soil, and in turn the growth of new plant life would not be possible. They are nature's digestive system, breaking down dead organic material into nutrient rich compounds that fuel the growth of new plant life. Their powerful ability to externally digest organic matter make them potent antibacterials in same cases.Molds of the genus Penicillium produce penicillin, which is used as an antibiotic. Molds also breathe oxygen and exhale carbon dioxide just like we do. This may work in perfectly if your goal is to grow lots of healthy plants, but too much of these molds in your home can cause a suffocating effect, further exacerbating the respiratory problems that are commonly associated with most types of mold exposure.

The Bad - Toxic Molds

There are more than 140 species of mold documented to be pathogenic or disease forming in humans.  Some molds can be so bad for you that they are considered the most toxic naturally occurring substances known to man. So toxic that it has even been used in biological warfare. The concentrated T-2 trichothecene mycotoxins (the same toxins found in Stachybotrys or toxic black mold) were responsible for thousands of deaths in Laos during the Vietnam war. Symptoms can vary drastically, ranging from severe headaches to nausea, vomiting, cancer and even death.

Most Common Types of Mold

Acremonium
Soil, dead plant material. Light colored. Slow growing in moist environments. Rarely infects humans, but can when   other conditions are present, or immune system is weak. If infection occurs it can be a real problem. This mold was previously known as Cephalosporium. Used to derive the class of antibiotics known as Cephalosporins.

Aspergillus
Toxic. Indoor, found in areas with high oxygen. This is a common contaminant of starchy foods such as bread and potatoes. It is known as the second most common mold to infect humans. This mold is also commonly found on damp walls. Watch for any signs of leaks or water damage.

Cladosporium
Indoor and outdoor, very common green to brown to black colonies. Found on living and dead plant material. This most commonly causes infections of the skin and toe nails.

Fusarium 
plants, soils, mostly harmless, in humans w bad immune systems: nails, cornea. used as a food and has been weaponized by the soviet union.

Mucor
white to gray/beige - plants, soils, most unable to infect humans because they cant stand warm environments, but those that do can cause a kind of flesh eating condition known as zygomycosis.

Stachybotrys
Occurs indoors and can cause serious illness and even death in humans. Best known as Toxic black mold, it is frequently associated with poor indoor air quality after water damaged building materials. All the symptoms listed below but heightened are very common with this mold.   

Alternaria
A major plant pathogen, Alternaria is are common allergens in humans which grow indoors. They can cause fevers and even lead to asthma. This mold is a fast spreader and is a large problem in human health. It has also been known to destroy crops.

Other Types of "Mold"

In some rare circumstances, mold isn't Fungus at all. The exceptions to the fungi rule are two types of mold previously believe to be members of the Fungi kingdom; slime mold, and water mold. Water and slime molds, as we later learned, are not fungi at all. This is important to acknowledge when identifying, and remediating these types of mold growths. These Fungi-like "molds" are classified as a diverse group of eukaryotic microorganisms known as protists. These Protists can be unicellular when food is abundant, or multicellular when it isn't. Unlike Fungi, their cells do not show differentiation into tissues in their multicellular form. Instead, each cell can change its role in the organism as it sees fit. This simple cellular nature is the primary difference that excludes them from the fungi kingdom. In most other respects, their behavior is considered very fungi-like.

These water and slime protists can be dangerous pathogens, such as in the case of Plasmodium falciparum, which causes malaria in humans. You don't have to worry about this particular protist growing in your air conditioner though, as it is an exclusive parasite of animals, but it does help to illustrate how dangerous some of these organisms can be to humans.

When does mold Form?

The most common mold growths are triggered by environmental factors, such as high humidity, temperature range, oxygen levels, and the existence of organic material for the mold to consume. These conditions can be inadvertently created as a result of many common household occurrences, such as:

- Flooding, or water damage such as pipe leaks
- Malfunctioning air conditioning units
- Rodent / insect infestations
- Ground water absorption
- Keeping a steady ambient temperature for long periods of time

Some of the most common household environments perfect for mold formation are air conditioners, AC ducts, in between sheetrock or wooden walls, and basements. Even slime molds have been found to grow in air conditioners.

How can you eliminate mold in your home?

The mold remediation process can be a real challenge. Spores travel quickly and can spread throughout your home completely undetected. Even when a small mold growth is properly cleaned up, you may have new formations beginning to grow elsewhere. In some cases sections of wall or ceiling may need to be replaced entirely as the mold will not only be deep rooted and difficult to annihilate, it may even compromise the structural integrity of your home.

Water damage is a major cause for concern in any household or building. Water damage does not occur only as a result of floods or heavy rain, but also due to seemingly innocuous problems such as a simple leak in a pipe. Water damaged walls are very common whenever there is a leak in a pipe that runs through a wall. Water may be the elixir of life, but it has proven to be severely damaging to our goods and property. The walls, wood and carpeting in our homes require protection from water sources, as they can be damaged far too easily. In the event of unforeseen water damage, immediate repair and restoration is essential in order to prevent further damage by mold and mildew. Restoration companies can provide the tools and expertise necessary to return your property to its former glory.

Substantial moisture combined with brick walls or fabrics is the perfect recipe for mold growth; hence, you will often find that damp walls, carpeting and wood all tend to house mold growth. Mold and mildew thrive in damp, cool places, meaning that any place where water remains stagnant for a long period of time will likely foster mildew growth. Mold can prove to be damaging to the objects on which it grows, compromising walls, carpeting and wood with upsetting ease. Since it is essentially a variety of fungi, mold should not be ignored. It can have negative effects on the environment of a home and the air we breathe, and may be especially harmful to babies and children who tend to stay very close to the floor.

Certain mold varieties can be toxic and may lead to severe health problems; therefore, mold should be destroyed at first sight. Prevent mold growth in the first place by taking steps to ensure that water damage does not occur. Dehumidifiers work well at removing moisture, and in the event that mold starts growing at a rapid pace, chemicals that treat and kill mold and its spores should be applied. You can carry out most basic mold removal techniques by yourself without any professional expertise, but when there has been severe water damage and a large amount of mold or mildew is present, it is best to consult a mold cleanup professional to undertake the inspection and removal process. Also, if you do not know much about mold or have trouble differentiating between regular and toxic molds, it would be better to leave the task to a professional. Black Mold in particular, requires special care; amateur attempts at removal are not recommended.

In the rare cases where water damage is truly unavoidable, proper measures should be taken to immediately remove moisture from the area. Usage of electronic dehumidifiers, silica gel, additional waterproofing of property and so forth are a few of the methods that one should consider. If you live in a region that is frequently subjected to heavy rains and a high water flow, purchasing mold insurance for your property might also be recommended. Water entering your property uninvited might be unavoidable, but these solutions for preventing water damage are always within reach.

Have you recently been facing respiratory problems such as wheezing or difficulty breathing? Do your burning, watery eyes worry you? Have you found that skin irritation, pains and aches are becoming regular problems for you? If the answer to any of these questions is yes, then you should consider hiring a mold removal company to conduct a mold inspection. Since mold originates form spores that can only be seen under a microscope, it is essential to use professional mold removal services to determine if your home is suffering from this vexing problem.

Apart from the health issues mentioned above, there are several others that are also associated with mold and mildew. These health threats may be exacerbated by the presence of black mold in the home. For general mold removal, you may take some steps on your own, but you will surely have to get in touch with a professional mold remover in order to safely accomplish black mold removal. Since mold has become a serious problem for many people, mold remediation has become a big business in recent years. Learn what mold remediation is all about:

Safely and thorough removing mold spores and existing colonies is known as mold remediation. It is an exhaustive process that is started by determining the source of the mold growth. Generally, mold grows in a hot and humid environment with enough moisture for the mold to thrive. After determining that mold is present in your home, certain remedies are recommended which may be tailored to your specific circumstances and mold type.

In the simplest cases, these remedies may focus on ensuring a sufficient level of sunlight in your home, along with better ventilation and the use of household cleansers. The best thing about mold remediation is that contractors can work according to your needs and problems. In this way, mold removal from the home can become much easier and more effective.

Basic remediation methods:

The methods of mold remediation may differ from building to building, but the following are the methods used in most cases:

• Using wet vacuum cleaners to remove water from carpets or other places

• Using damp wipes for mold removal from non-porous surfaces

• Using detergent or mold removal bleach

• Using a High Efficiency Particulate Air (HEPA) filtered vacuum in order to ensure that mold is no longer present in the home

Equipment used in mold remediation:

Before, during and after the employment of these mold removal methods, it is essential to have the right equipment on hand in order to kill mold properly.

• A moisture meter is one of the most important tools, as it informs the user of the moisture level in a house. By using this tool, one can easily determine whether or not a house has an ideal moisture level.

• A humidity gauge should be used hand in hand with a moisture meter, since both of these tools can help determine the levels of the most basic factors in mold growth.

• A Borescope and a digital camera: The Borescope is used to ensure that mold is not present inside the walls, while the digital camera helps to capture certain elements required during an assessment.

Apart from these basic tools, you may see some contractors using devices including personal protective equipment, thermographic cameras, dehumidifiers and so on. Due to the availability of these and other indispensable tools, the process of mold remediation has become much easier. 

How do i know if I have mold?

How do I know if I have mold?

Many people in South Florida are not aware that exposure to mold can have serious adverse effects on your well-being. Mold exposure is usually misdiagnosed as a number of other conditions because the symptoms are so varied. But exposure to mold spores can have very detrimental effects in the long run, such as cancer, lung problems, brain damage, and ultimately death.

            It can be tricky to discern whether your house has become a victim to mold many people live day in and day out with toxic mold spores and don’t even realize they are there. The first step to identifying mold is to look for black or green spots around your house. Mold can grow in any environment where there is moisture, so look for condensation around any glass windows or doors in your home. The condensation will look like little water droplets around the glass. Also, if you have mold, your house will start to get a distinct musty smell, like clothes that have been left wet for a long period of time. Even if the smell is not overwhelming, a damp smell is a tell tale sign of mold.  Any place in your home that is damp whether it is because of a leak or inadequate ventilation can be susceptible to mold and should be inspected thoroughly.

It’s important to note that mold can grow virtually anywhere, including furniture and carpets. Mold that is found on other places besides the walls or ceiling is called mildew. Look for mildew in damp places around your house. A good starting point is your bathroom, and makes sure to give special attention to your shower and bathtub. Mildew has an almost powdery appearance, and it will either be gray or white. 

            After a flood, there is always more potential for mold to propagate because of all the moisture that comes into a home. You cannot rely on things to air dry because this can be a perfect breeding ground for toxic mold. It is important to fix any leaks in your roof or pipes immediately to prevent mold spores. If you have experienced flooding in your house, contact a mold remediation specialist to seek help. 

            A homeowner should waste no time hiring a professional when the problem arises, because mold will continue to grow until it becomes very difficult to repair. Mold remediation is definitely the way to go once you have identified mold in your house, because experts can help you identify the source and eliminate this serious problem with safe and appropriate remedies.
