Abstract

Measurement and analysis of Particulate Matter of aerodynamic diameter less than 1µm (PM1) has been carried out using indigenously built air sampler at the following locations of Bengaluru city: Basavanagudi (BAS), Domlur (DOM), Hosur road (HOS) and DC Halli (DCH). The PM1mass concentrations were observed to vary from 20.16 µg/m3 to 68.64 µg/m3 during the study period. The highest mass concentration of 68.64 µg/m3 was observed for the location BAS and the lowest mass concentration of 20.16 µg/m3 was observed for the location DOM. The average mass concentration of PM1 around Bengaluru for winter, summer, monsoon & post monsoon season is observed to be 47.60 µg/m3, 40.24 µg/m3, 30.85 µg/m3 and 38.76 µg/m3 respectively. Some of the collected samples showed the presence of microorganism such as bacillus. Elemental composition analysis showed the presence of non-metals Carbon, Oxygen, Nitrogen, Sulphur and traces of metals such as Sodium, Aluminium, Calcium and Potassium.
