Abstract
Indoor air quality is of great importance for human health as people spend a large part of their lives indoors. In
this study, particulate matter (PM₁, PM₂.₅, and PM₁₀) concentrations were monitored in three residential
microenvironments — the living room, the kitchen, and the bedroom — in a house in Ballari, Karnataka, India, using a
low-cost portable air quality monitor. In addition, both the indoor temperature and the relative humidity were monitored
to examine their effects on particulate matter concentrations. Hourly measurements were taken over 15 consecutive days
(March–April 2025), with five days of monitoring in each microenvironment. A temporal analysis found short-term
increases in particulate matter concentrations during periods of increased household activity. The relatively high PM
levels in the living room were likely due to the ingress of outdoor dust, whereas the bedroom had comparatively lower and
more stable concentrations. The results showed clear differences in particulate matter levels among the areas under
investigation.
Indoor air quality is an important concern as people spend much of their time inside buildings and may be exposed to pollutants from various indoor activities. This study examined the hourly concentrations of formaldehyde (HCHO) and total volatile organic compounds (TVOC) in a residential building in Ballari, Karnataka...

Understanding air pollutant behaviour and interactions has become increasingly important due to the growing impact of air quality on human health and environmental conditions. Indoor Air Quality (IAQ) has emerged as a significant metric for public health concerns in recent decades. Recent studies indicate that people s...
To investigate the indoor air quality on middle school campus in China, PM2.5 samples in a classroom and a laboratory during summer and winter at a y middle school in a coastal city of China were collected and analyzed for their chemical composition and sources. Our results showed that the average winter and summer PM2...
