Assessment of Indoor Fine and Ultra-Fine Particulate Matter in a Research Laboratory
Indoor air quality (IAQ) has drawn the attention of all the scientific community around the globe as it ranked one of the top five risks to public health throughout the world. People spend most of their time in indoor environments, be it in their home or workplace, without knowing that they are inhaling substantially high concentrations of different indoor air pollutants (IAPs). In developing countries, IAP concentrations are generally found high due to poor ventilation and numerous indoor sources. Poor IAQ can adversely obstruct the mental, physical and social ability of a person, which can affect the working efficiency and result into loss in overall productivity. Along with other IAPs, high level of PM in indoor environments is one of the major concerns. The present study is an attempt to assess the exposure levels of PM10, PM2.5 and PM1 in one of the research laboratories, located in an industrial area of Delhi city. The monitoring is carried out at different indoor environments of the building. The preliminary results indicate that average concentration of PM10, PM2.5 and PM1.0 are highest in chemical laboratory, i.e., 114 ± 25 µg/m3, 58 ± 10 µg/m3, 33 ± 5 µg/m3, respectively and lowest at un-disturbed area, i.e., 42 ± 4 µg/m3, 33 ± 2 µg/m3, 22 ± 2 µg/m3, respectively. Ratio of PM2.5/PM10 and PM1.0/PM2.5 are found higher at un-disturbed area, i.e., 0.79 and 0.75, respectively as compared to other areas. It indicates that fine and ultra-fine particles travel more from outdoor compared to larger particle and suspend for longer time in the environment. Further, the study also discusses the possible measures to control the indoor air pollution and prioritize the indoor air-purifying plants based on their efficiency.
