INDOOR POLLUTION CAUSES AND PREVENTION
Indoor pollution and concrete air quality have been listed as two of the world’s worst pollution problems. The microbial presence and concentration in air especially in hospital environments where hospital equipment are very extensively used are often of high concern. The indoor pollution aspects are mainly classified into four categories: UV organic compounds, volatile organic compounds, non-volatile organic compounds, and particulate contaminants. In general formaldehyde could also pose to be a highly volatile organic compound, but no smell is sensed if the concentration of formaldehyde may be a smaller amount and when the concentration increases, it can be recognised by the smell, and later to feel a stimulus to nose, eye and throat then discomfort. And at very high concentrations, tears are induced and an individual may fall into dyspnoea. And as the concentrations reach to greater concentrations, it could be fatal. In order to deodorize formaldehyde, an amine compound is includi...
