There is a growing concern regarding the adverse health effects due to indoor air pollution in developing countries including India. Hence, it becomes important to study the causes and sources of indoor air pollutants. This study presents the indoor concentrations of PM_0.6 (particles with aerodynamic diameter less than 0.6 μm) and identifies sources leading to indoor air pollution. Indoor air samples were collected at IIT Kanpur campus. Ninety-eight PM_0.6 samples were collected during November 2013 to September 2014. PM_0.6 concentration was measured using a single stage impactor type PM_0.6 sampler. The average PM_0.6 concentration indoor was about 94.44 μg/m³. Samples collected were then analysed for metal concentrations using ICP-OES (Inductively Coupled Plasma – Optical Emission Spectrometer). Eight metals Ba, Ca, Cr, Cu, Fe, Mg, Ni and Pb were quantified from PM samples using ICP-OES …
