Indoor air quality is a term used to describe the quality of air in a particular building as it relates to the health of people living around and in the building and its environments (Agbagwa et al., 2014).
Washrooms are places with constant availability of moisture- a major contributing factor that promotes the growth of microorganisms, and some dissolved minerals that supports microbial growth, as such, will harbor lots of microbes. Problems of indoor air quality are known as vital risk factors for human health. Indoor air is significant also because people spend a considerable fraction of time inside buildings. In houses, day-care centers, retirement homes and other distinctive environments, indoor air contamination affects populations …show more content…
The average individual inhales about 10 cubic meters of air each day, roughly the volume of the inside of an elevator (Stetzenbach et al., 2004). Because people typically spend so much time indoors, poor indoor air quality can greatly affect individuals and, more broadly, the public health.
These microorganisms are carried and transferred by bio aerosols (Wojtatoweicz et al., 2008). Bio aerosols are colloidal suspensions formed by droplets of liquid and particles of solid matter in the air, which contain microbes and cell fragments combined with byproducts of cellular metabolisms. In addition, they may carry viruses, bacteria, and fungi that float on dust particles along with cells and parts of cells (Karwowska, 2005).
The presence of many biological agents in indoor environments is attributable to humidity and insufficient aeration. Excess moisture on almost all indoor materials leads to growth of microbes. Furthermore, dampness initiates chemical or biological degradation of materials, which also pollute indoor air. Dampness has therefore been proposed to be strong, consistent gauge of risk of asthma and respiratory signs. The health risks of biological contaminants of indoor air could thus be addressed by considering dampness as the risk indicator (WHO, …show more content…
Many fungi that are reported to cause allergy belong to Ascomycota, Basidiomycota or anamorphic fungi. Fungi are able to grow on almost all natural and synthetic materials, especially if they are wet (Portnoy, 2003). These microbes can enter buildings directly or by spores being carried in by the air. In a home or building, fungi are usually found on wood, drywall, ceiling tiles and carpeting. The key factor is moisture because fungi need it to grow. As a result, they are most often found in basements, kitchens and
