The main objectives of the study were to measure the indoor air quality in hospital with special emphasis on particulate matter (PM10, PM2.5 and PM1.0).

Concentrations of water soluble ions (Na, K, Ca and Mg) in PM10 alongwith gaseous pollutants (NO2 and SO2) were measured during summer season of 2009. The sampling site is located near National Highway which is a high traffic density site.
