| Research Abstract |
The behavior of indoor particulate matter as it relates to pets was studied from the viewpoint of architectural hygiene. The viable particles from pets can be classified into two types, pathogenic microorganisms and pet allergens. This study investigated Pasteurella, which is a pathogenic organ of Pasteurellosis, dog allergen Can fl and cat allergen Fel dl, gaseous contaminants, airborne microbes and other indoor contaminants. Pasteurella and the pet allergens were quantified by biochemical and immunological methods, respectively. Indoor air pollutants were measured in Shanghai, Taiwan and 'Tokyo because that area of indoor environments and housing method could be different. And the counter measure effects for indoor pet contaminants were investigated by measuring indoor allergen and contaminants.
Indoor allergen in all three cities were found instead of indoor temperature, while mite allergen has a seasonal effects. The dogs and/or cats generated allergen and particulate matter into indoor air by allowing free access to indoor areas.
These findings suggest that the traditional reduction method for coarse particles, for example the use of a domestic air filtration cleaner, could be effective in removing airborne pet allergens.
