Analysis of particulate matter (PM10 & PM2.5) level and meteorological effects during winter season at rajiv gandhi institute of chest diseases hospital campus in bengaluru city

The need of study the properties of Particulate matter (PM) and their distribution of particles in different hospital environment and top priority of this study is to control air pollution in hospital environments. PM 2.5 is the mass concentration of fine aerosol with aerodynamic diameter less than 2.5 µm whereas, PM10 is the mass concentration with aerodynamic diameter of 10 µm.PM10 and PM2.5 were measured in ambient levels at Rajiv Gandhi Institute of Chest Diseases Hospital Area and compared with Victoria Hospital area PM10 data. Simultaneously, the meteorological parameters (air temperature, relative humidity, wind speed and wind direction) was recorded by the Envirotech WM 271 wind sensors. The average levels PM10 was exceeded the Revised Ambient Air Quality Standards for 123 µg/m3(RGICD) & 149 µg/m3(Victoria) and PM2.5 was in permissible limit 40.37µg/m3. Samples of particulate matter were collected during winter season from the hospital area. Qualitative analyses of particulate matter were performed using scanning electron microscope based on morphology the size and shape of the particles.
