Welcome to 411 Mold - MOLD INSPECTIONS & TESTING

 The most common mold spore species to appear in indoor air samples. The majority of the hundreds of sub-species are allergenic; only a few are toxic. This group of species only grows with the humidity in the air as its water source.  For people with healthy immune systems, breathing in Aspergillus isn't harmful. However, for people who have weakened immune systems, breathing in Aspergillus spores can cause an infection in the lungs or sinuses which can spread to other parts of the body. The airborne spores GENERALLY should be less than approximately 1,500 cts/m3. Aspergillus /Penicillium and other hyaline spores are on average less than 700 cts/m3. Indicator fungi such as Stachybotrys, and Chaetomium can point to longer-term water issues as these spores are late bloomers, so to speak.  Fungi such as Aspergillus and Penicillium are often found colonizing adhesives and caulks, with Penicillium in particular found associated with PVC, plastic, and rubber. Aspergillus is associated with surface discolorations of polyesters. 

Cladosporium is a common mold that can affect the inside or outside of a person's home. Most kinds of Cladosporium are not dangerous to humans, but sometimes they may lead to allergies, or they may worsen asthma. In rare cases, Cladosporium may lead to infections.  The genus Cladosporium has been reported to cause several different types of opportunistic infections, including subcutaneous and deep infections, in humans and animals. Cladosporium spores, which potentially lead to the development of respiratory allergy problems such as asthma, rarely cause pulmonary infection.  Although Cladosporium is not known to produce dangerous mycotoxins, it produces Volatile Organic Compounds (VOCs) associated with odors. The classic musty smell is a good indicator that Cladosporium species are present.  Cladosporium is among the most widespread varieties of mold that homeowners encounter. It presence is indicative of high moisture levels and poor indoor air quality. Cladosporium is highly allergenic and can reduce your health and overall quality of life. It is dangerous and can spread through the house rapidly. 

 Fusarium colonies are usually pale or brightly colored (depending on the species) and may have a cottony aerial mycelium. Their color varies from whitish to yellow, brownish, pink or reddish. Species of Fusarium typically produce spores (called macro- and microconidias) for reproduction and dissemination. Airborne concentrations vary seasonally and constitute a small proportion of the natural aerosolised fungal flora in northern climates; although present year-round, the highest numbers of airborne Fusarium are recorded during summer.  Fusarium colonies are usually pale or brightly colored (depending on the species) and may have a cottony aerial mycelium. Their color varies from whitish to yellow, brownish, pink or reddish. Species of Fusarium typically produce spores (called macro- and microconidias) for reproduction and dissemination. Fusarium is a common mold that can be found just about everywhere. It is often found on soil and plants, both indoors and out. It can grow on many types of food, and on many surfaces, particularly those that have suffered water damage. Fusarium can grow and spread at lower temperatures.  

 Stachybotrys chartarum is a greenish-black mold. It can grow on material with a high cellulose content, such as fiberboard, gypsum board, and paper. Growth occurs when there is moisture from water damage, water leaks, condensation, water infiltration, or flooding. Constant moisture is required for its growth. A variety of respiratory, dermatological, eye and constitutional symptoms have been associated with heavy and prolonged exposure to Stachybotrys chartarum. Stachybotrys chartarum has also been potentially implicated as a rare cause of idiopathic pulmonary hemorrhage in infants. Infants, older adults and people with asthma, chronic obstructive pulmonary disease (COPD) or a compromised immune system are more likely to experience black mold allergies. Stachybotrys chartarum is especially dangerous for asthmatics and can cause shortness of breath, cough, chest tightness, wheezing and asthma attacks.  In our experience, anything above 50 spores per cubic meter of indoor air should be cause for concern. In any case, proper maintenance of heating, ventilation, and air-conditioning systems, removing dust, and cleaning carpets regularly all help to keep the spore count at a low level.
