Calgary-based Astra Restorations knows all too well the hazards toxic mould can pose to health. While treating mould yourself can jeopardize both your health and your property, knowing how to recognize toxic mould and understanding the effects toxic mould can have on your health and property is essential.
While “black mould” is the most commonly known toxic mould, there are actually a number of other moulds which pose serious risks to health and property. The most common indoor moulds are Stachybotrys chartarum, Cladosporium, Penicillium, Aspergillus, Alternaria, and Trichoderma.
Stachybotrys chartarum is a black mould that is prevalent in water-damaged buildings, especially flourishing on damp drywall and wallpaper surfaces.
Cladosporium is a fungus that grows indoors and outdoors, can vary in colour from olive to brown or black, and grows on moist organic and inorganic surfaces.
Penicillium is a mould sometimes used to produce antibiotics. It can grow in relatively low-humidity environments, as long as the surface is damp. Some species can produce mycotoxins dangers to human and animal health, causing respiratory problems, particularly in infants.
Aspergillus is a spore-forming mould that commonly contaminates root vegetables, but is often found also on nutrient-deficient surfaces like damp walls. It is a common component of mildew. Some species cause serious pathogenic disease in humans.
Alternaria species are ubiquitous in the natural world and commonly cause allergenic and hyper-sensitivity responses in humans – as well as opportunistic infections in the immunocompromised. While a normal part of decay and decomposition, in the home these spores can grow thick grey, black, or green colonies, producing a variety of toxic compounds.
Trichoderma is a mould found in the home that produces small toxic peptides readily absorbed into human cells. Here, they interfere with ion channels and cell function. Resistance to antimicrobials means that primary prevention for this mould is the only effective option for limiting its effects.
