Mold Types - Black Mold, Toxic Mold, Mildew

Different types of mold - black mold, toxic mold, allergenic mold - are present all the time around us and in the air we breathe. In low levels, molds and mold spores are generally harmless but if their levels increase they can affect people; especially people with allergies, asthma and respiratory conditions or suppressed immune system.

Allergenic mold and mold spores are normally not dangerous to humans in low amounts, but they cause allergic or asthmatic symptoms. Generally, these types of mold can be relatively easy and safely cleaned and removed. Note that even dead mold spores or mold particles can trigger allergy symptoms or allergic reactions.

Mycotoxic mold and mold spores are those containing toxins in the cell wall. These types of mold can cause serious health problems in humans and animals. These molds range from short-term irritation to immunosuppression, to cancer and even death. If toxic molds are identified, it is suggested that you seek advice from an Industrial Hygienist or other mold professional for guidance. The average homeowner should NOT attempt the abatement of these types of mold.

Pathogenic mold is the type of mold that causes infections. Pathogenic molds can cause serious health effects in persons with suppressed immune systems, those taking chemotherapy, and those with HIV/AIDS, or autoimmunity disorders. If any pathogenic molds are identified, it is suggested that you seek advice from an Industrial Hygienist or other mold professional. The average homeowner should NOT attempt the abatement of this type of molds.

Hyphae & hyphal elements are single, unidentifiable fragments of mold. Although they might not be traceable to a specific mold species, these fragments can be responsible for allergic reactions in some people and may indicate previous or current growth. Ascospores and basidiospores are clusters of spores that may not be easily identified as a specific species, but may represent a mold problem in the property.
