Abstract
Air pollution is viewed as a significant environmental problem around the world due to urbanization and industrialization. Indoor air quality is a major concern compared to outdoors, as individuals spend about 80-90% of their time indoors. This study discusses the comparative assessment of indoor and outdoor air quality through PM2.5, PM10, HCHO and TVOC concentrations obtained from eight residential houses in Jamia Nagar, New Delhi. A portable air quality pollution meter detector manufactured by Smiledrive was used which works on light scattering principle. The monitoring was conducted in the months of February to April, 2023. The instrument was placed in the kitchen for indoor air quality monitoring and on the balcony for outdoor air quality monitoring. The monitored data was used for analysis using Microsoft Excel. In all the well-ventilated houses, the differences in concentration of indoor and outdoor air parameters observed was less compared to poorly ventilated houses. Peaks in the variation of indoor parameters were observed during indoor activities. Thus, it can be concluded from the present study that the ventilation characteristics and indoor activities play a significant role in the elevated concentration of indoor air parameters.
