Current research work is aimed for assessment of ambient air quality of Chachai region. The objective of the study is to know the effect of coal based thermal power plant emission on air quality in the vicinity of Amarkantak Thermal Power plant. The monitoring and estimation of Particulate Matter (i.e. PM10 and PM2.5), SOx and NOx was done in three consecutive seasons. Significant variation was observed in distribution of particulate matter, as the concentration of PM10varied from 66µg/M (min.) to 129µg/M (max.) while PM2.5 was record 26µg/M (min) to78µg/M (max.). The higher particulate in summer is the result of enhanced dispersion of fugitive dust appends by coal and ash handling activity and in winter can be attributed to low temperature and low wind speed. The lowest concentration during monsoon season may be attributed to washout by rainfall and also due to higher relative humidity, which reduces re–suspension of dust. The SOx ranged between 38µg/M to 98µg/M and NOx from 33µg/M to 94µg/M. Non-functionalizing of water sprinkling system, ESP, Bag filters may also be the active causes for increasing of environmental pollutants in the surrounding area of TPP. After Air samples analysis the results were compared with Maximum permissible limit as per Guidelines provided by Central Pollution Control Board new Delhi (CPCB) for National Ambient Air Quality Standard (NAAQS) 2009. The collected data were statistically analysed with Pearson Correlation Matrix for examining the effects of Environmental Pollutants on Ambient Air Quality at site. The analysis was performed for seasonal alteration and overall annual interactions on different parameters.
