Air pollution is currently the greatest environmental threat to human health and one of the fastest growing issues on the global health agenda. The extremely fine particulate matter (aerodynamic diameter < 2.5 microns) is of greatest concern because the particles can penetrate deep into human lungs and enter the bloodstream. The elderly, asthmatics and immune-deficient population are the most vulnerable with the increasing levels of particulate matter. The present study was conducted to assess the concentration of size-segregated Indoor Particulate Matter (PM2.5, PM1.0, PM0.50, PM0.25) in Sunderbani, Rajouri, J&K. The average values of PM2.5, PM1.0, PM0.50, and PM0.25 were reported as 110.36µg/m3, 180.50µg/m3, 276.99µg/m3 and 445.93µg/m3 respectively in the sampled households of the study area. The average value of PM2.5 in the study area was found to be above the permissible limits of 60µg/m3 given by central pollution control board (CPCB). This was the first study on concentration of size-segregated particulate matter in the indoor environment of study area and the data obtained from the study will serve as baseline data for future studies in the area.
