Disaster recovery and restoration can be veiled in mystery to the many who have not undertaken specific training. This glossary explains technical terms to assist both report writing and the understanding of those technical terms so often misunderstood.
Definition
| Aerobiology: |
The scientific discipline that studies airborne allergey producing substances including dusts, mites, pollens, mold and animal dander. Scientists and microbiologists specializing in airborne contaminates research and investigation are called aerobiologists. |
| Aerollergens: |
Airborne allergen producing substances such as dust, mites, pollens, mold and other airborne substances, from animal dander and hair to human skin cells. Education Note: Aeroallergens can be a vapour from perfumes or toxins from organic decay. See Aerobiology, Aeolian Contamination, Allergens |
| Allergy: |
A number of disease symptoms caused by exposures to the skin and of the respiratory system. Dusts, molds, mits, grass, animal dander and pollens are some of the primary allergens that cause persons to suffer from allergies. Health Note: Water damaged buildings are known to increase indoor allergens and mite activity. The use of airmovers during building drying are known to cause some allergy sufferers to leave contaminated buildings. |
| Animal Dander: |
Small and microscopic size flakes of shed animal skin and hair (including body oil, urine and feces). Education Note: Animal dander produce allergens and persons susceptible to certain animal dander have lgE antibodies to such allergens as cat FEL d-l (Duffort et al,. 1991). Persons suceptible to animal dander will most likely develop symptoms rapidly when entering a house where animals like cats are present, since this allergen is constantly airborne (Van Metre et al., 1996). Although there are significant differences in allergen content in homes with or without pets, many homes that are normally without a cat, nonetheless contain surprisingly high levels of Fel d-l in household dust (Wood et al., 1998). It is felt that the homes not having animals present, the allergen from animals is brought into the house on the clothes of the inhabitants . Levels of cat allergen, for example, as low as 2 ug Fel d-l/g of household dust, commonly onserved in dust sample studies of houses without cats, may be a risk factor for sensitization to Fel d-l (Wood et al.,1998). See Antigen. |
| Antibiotic: |
a) A chemical substance, excreted by microrganisms or synthetically produced that has the capacity to inhibit or kill bacterial infections when applied in dilute solutions. b) An immune system response from a chemical or biological substance including fungi and bacteria that react and are capable of producing allergic reactions in human. see Allergic Reaction, Animal Dander, Endotoxin, Mycotoxin, Toxin |
| Antigen: |
Any substance, chemical, particle or toxin that causes the formation of an antibody. b) An immune system response from a chemical or biological substance including fungi and bacteria that react and are capable of producing allergic reaction in humans. See Allergic Reaction, Animal Dander, Endotoxin, Myotoxin, Toxin |
| Bioaerosol: |
a) Bioaerosols are airborne particles of biological origin including bacteria, and viruses, fungi and yeasts, pollens and organic matter. Bioaerosols also include the cell structures and spore parts of non-viable components (such as toxins). b) An aerosol containing living organisms or particles derived from living organisms such as pollen, animal dander, insect emanations, microbial endotoxins, and human skin scales. c) An airborne organic contaminant that is either generated by or is itself a living organism such as fungi, bacteria, viruses and protozoa. Education Note: Moisture-vapor and airborne contaminates from a flooded building that are forced in air from a surface, through dynamic air movement contain bioaerosols.
