Indoor air pollution has aroused increasing concerns due to its significant adverse health impacts. Indoor PM exposure assessments often rely on PM concentration measured at a single height, which overlooks the vertical variation of PM concentrations accompanied by various indoor activities. In this study, we characterize the vertical profile of PM concentration by monitoring PM concentration at eight different heights in the kitchen and the bedroom, respectively, using low-cost sensors with high temporal resolution.

Indoor air pollution has significant adverse health impacts, but its spatiotemporal variations and source contributions are not well quantified. In this study, we used low-cost sensors to measure PM concentrations in a typical apartment in Beijing. The measurements were conducted at 15 indoor sites and one outdoor site on 1-minute temporal resolution (convert to 10-minute averages for data analysis) from March 14 to 24, 2020.

Article Synopsis
  • Household air pollution is a major but often overlooked contributor to overall air pollutant exposure, outpacing concerns about outdoor pollution.
  • In a study focusing on indoor gas pollutants like CO, formaldehyde, and VOCs, it was found that indoor concentrations were significantly greater than those outside, highlighting the impact of cooking and human activity on indoor air quality.
  • A new statistical method was introduced to estimate the sources of indoor pollution, revealing that outdoor air and cooking are key contributors, with vertical measurements indicating higher pollutant levels in upper kitchen areas due to hot air rising.
