Abstract
Particulate pollution is very abigissue in coal mining area. The particulate matter affects human as well as nearby animals, vegetation and degrade the ecological environment in many ways. So every time it is fetching the attention of researchers to find work on the issue. Talcher coal field, one of the oldest coalfields of India with a very high coal deposit. A monitoring of respirable dust (PM10& PM2.5) has been performed at eight monitoring stations around a high mechanised opencast coalmine for two seasons i.e., summer and winter. Samples were collected as per the standard criteria of central pollution control board (CPCB), India. Winter season was found to have more particulate concentration as compare to summer. A total of 10 trace elements were analysed and selected for source apportionment of particulate matter and associated heavy metal. Statistical analysis such as univariate (correlation study) and multi variate statistical analysis were used including principal component analysis (PCA) for source identification and respective contribution to particulate matter. The major sources of trace metals were mainly coal mining and associated activities, vehicular emission etc.
