Quantification and Assessment of Indoor PM2.5 in North Indian Precinct

One of the major global causes of indisposition and impermanence, affecting both women and children in developing and under developed nations alike, is indoor air pollution. Exposure of children to PM2.5 in metropolitan environments poses very serious health hazards. Compared to other air pollutants, fine particulate matter (PM2.5) is known to pose substantial health risks. The goal of the current study is to quantify the levels of PM2.5 in both the winter and summer months while also examining seasonal variation. Using Envirotech APM 550, sampling was carried out from November 2021 to June 2022. The sampler was positioned indoors in urban dwellings in the Indian city of Lucknow. A total of 24 homes were chosen. The study also evaluated climatic conditions and identified influences on the concentration of the particle pollution. According to the findings, winter time PM2.5 concentrations were higher than summer time ones. The average indoor PM2.5 concentration during the winter was discovered to be 228.62 ± 29.5 µg/m3, whereas the concentration during the summer was noted to be 137.18 ± 21.3 µg/m3. Health risks assessment (HRA) on children under the age of 18 ranged from 0.06 * 10–6 in the winter to 0.026 * 10–6 in the summer.
