Absolute levels - The total spore concentration at any given location.
Airborne mould - mould spores. (See Spores).
Air Sample (Viable) - A viable air sample identifies the types of organisms present in a location, that are capable of growing if the optimum conditions for growth are provided. A viable air sample is collected by impacting a known volume of air onto the surface of a nutrient media. The nutrient media is incubated for a period of time during which the organisms mature and then can be identified and enumerated by the laboratory.
Air Sample (Non-Viable) - A known volume of air is impacted onto the surface of an adhesive which captures the particulate matter present including but not limited to fungal spores, pollen and skin cells. The particulate matter collected can then be identified and enumerated by the laboratory. Examples of non-viable air samples include the Zefon Air-O-Cell.
Bacteria - A group of unicellular prokaryotic organisms, some of which are important as pathogens and for their biochemical properties.
Biocide - Substance or chemical that kills organisms such as moulds.
Biodegradable - A material capable of being broken down by microorganisms.
Dander - The tiny particles of skin and dried sweat and saliva that are shed by animals such as cats and dogs. These are a major cause of allergies.
Fungi - Fungi are neither animals nor plants and are classified in a kingdom of their own. Fungi include moulds, yeasts, mushrooms, and puffballs. In this document, the terms fungi and mould are used interchangeably. moulds reproduce by making spores. mould spores waft through the indoor and outdoor air continually. When mould spores land on a damp spot indoors, they may begin growing and digesting whatever they are growing on. moulds can grow on virtually any organic substance, providing moisture and oxygen are present. It is estimated that more than 1.5 million species of fungi exist.
Fungicide - Substance or chemical that kills fungi.
Genus - Taxonomic rank below family. Examples of genus level names are Cladosporium, Alternaria and Pithomyces. These names are always capitalized.
GNB - Gram Negative Bacteria.
HEPA - High-Efficiency Particulate Air
HERTSI-2 - Health Effects Roster of Type Specific formers of mycotoxins and inflammagens - Second version.
HVAC - Heating Ventillation & Air Conditioning System.
Hypersensitivity - Great or excessive sensitivity
Mould - Moulds are a group of organisms that belong to the kingdom Fungi. In this document, the terms fungi and mould are used interchangeably. There are over 250,000 identified species of mould but some literature suggests there may be as many as 1.5 to 2 million species -so this suggests many are yet to be discovered.
mVOC - Microbial volatile organic compound, a chemical made by a mould which may have a mouldy or musty odor.
Mycoflora - The fungi characteristic of a region or special environment.
OSHA - United States Occupational Safety and Health Administration
Outdoor Air Sample - A sample taken from an outdoor source. Usually compared with an indoor samples to determine if there are elevated concentrations of spores indoors.
PAPR - Powered air purifying respirator
PCR - Polymerase Chain Reaction - a method of genetically amplyfying specific DNA to improve detection sensitivity
PPE - Personal Protective Equipment
Protein - Any of a group of complex organic compounds that are composed of amino acids.
Remediate - Fix
Rhinitis - Rhinitis is an inflammation of the mucous membrane that lines the nose, often due to an allergy to pollen, dust or other airborne substances. Seasonal allergic rhinitis also is known as "hay fever," a disorder that causes sneezing, itching, a runny nose and nasal congestion.
Sensitization - Repeated or single exposure to an allergen that results in the exposed individual becoming hypersensitive to the allergen.
Spore - moulds reproduce by means of spores. Spores are microscopic; they vary in shape and size (2-100 micrometers). Spores may travel in several ways—they may be passively moved (by a breeze or waterdrop), mechanically disturbed (by a person or animal passing by), or actively discharged by the mould (usually under moist conditions or high humidity).
Ubiquitious - Commonly occuring.
Viable Spore - A spore capable of germination.
