Abstract
The scope of this study was to determine the concentration and composition of atmospheric particulate matter of aerodynamic diameter < 10 μm (PM10) in the vicinity of coal-fired Ropar thermal power plant near Chandigarh, India. Two sampling sites, one inside the thermal plant and the other, outside the thermal plant were chosen. The elemental analysis was done using Proton Induced X-ray Emission (PIXE) technique. The elements detected at both the sites were common i.e. Si , S , Cl , K , Ca , Ti , Cr , Mn , Fe , Co , Ni , Cu and Zn however, their concentration vary at both the sampling sites. Also, Principal Component (PC) and Enrichment Factor (EF) analysis were done in order to identify the contributing elemental sources towards the particulate matter. Contributing sources to the elements were found not only the emission from the coal-fired thermal power plant but also from other activities like vehicular emissions, household cooking and natural soil dust etc.
