Indoor air pollution 2

Last blog, I introduced causes and effects of poor indoor air quality, this blog, I will provide some solutions to deal with indoor air pollution. From the source of pollution, there are several basic methods to control indoor air pollution include source control, source isolation, increased ventilation, dehumidification, and filtration. Possible sources of contamination should be considered in source-control strategy. For example, banning smoking in public buildings, using carefully selected building materials to avoid the emission of toxic or irritating substances, and limiting the use of fibrous materials. Source-isolation strategy is used in situations where a source cannot be completely eliminated. For instance, copy machine areas, food service stations, and bathrooms are often separately set outside buildings to avoid the recirculation of return air. Increased ventilation and filtration are traditional approaches to ensure good indoor air quality. Dehumidification helps in the reduction of microbial growth. Low humidity should be maintained inside a house to limit the growth of such bacteria.

Indoor air quality plays an important role in people’s health. when I searched for indoor air quality, a study caught my attention, which is people spend average eight hours at home, for women in China, they would spend more than this average time. Therefore, poor indoor air quality is much harmful for health.
