In terms of ubiquitous molds which are registered in our environments, both indoors and outdoors, the Cladosporium genus of mold is certainly one of the most prevalent ones. When air tests are conducted, the Cladosporium genus of mold will often be present due to the prevalence outdoors. Regardless of the ubiquity of such a mold, there can still be indoor mold issues which arise and produce elevated levels of Cladosporium indoors-whether it be an indoor air quality issue due to the reproduction and sporulation of the respective mold, or visible growth in more furtive types of areas, such as HVAC air ducts.
A continual great source of indoor air quality matters is the American Industrial Hygiene Association. In one of their publications regarding mold growth within indoor environments, it is noted that,
"The US Centers for Disease Control and Prevention (CDC), the Institute of Medicine of the US National Academy of Sciences, the World Health Organization, and Health Canada all agree that living or working in a building with mold damage results in increased risk of respiratory disease"
Due to the consensus on the effects of mold via the mycotoxins they produce, which can be detrimental to human health, it is worth analyzing each genus of mold to further understand how it may alter the way we interact with our environments. Therefore, the following list outlines various facts about the Cladosporium genus of mold:
1. WHERE IS CLADOSPORIUM FOUND? In the outdoor environment, Cladosporium is commonly found on plants and on decaying organic matter, whereas indoors, Cladosporium is generally found on moist wallpaper and carpet, as well as HVAC ventilation covers.
2. DOES CLADOSPORIUM CAUSE HEALTH EFFECTS? According to the Center for Disease Control (& Prevention), Cladosporium seldom causes actual human illness, however, myriad infections can be caused by Cladosporium, such as: skin infections, eye infections, sinus issues and even brain infections. Furthermore, typical allergy symptoms have been associated with Cladosporium, as well as asthma triggers (CDC, 2015).
3. WHAT DOES CLADOSPORIUM LOOK LIKE? The Cladosporium genus has a wide range of color in terms of the appearance-ranging from dark green to black. If there is concern in your property and you would like it identified, mold testing companies can perform surface swab testing or tape lifting sampling on the mold to identify it through an accredited lab.
