Abstract
Some coal-fired thermal power plants (cTPPs) in India intermittently show episodes of air pollution and public health risk. Khaparkheda and Koradi cTPPs in Nagpur district, Maharashtra, India are showing higher air pollution levels and health problems since the year 2015. These cTPPs are located at around 6 km distance from each other. With this background, the air pollution around the Khaparkheda Thermal Power Station (KTPS) was studied during summer month of 2018. National Ambient Air Quality Standard (AAQS) and WHO standard were used to interpret the data. The air pollutants were observed to be more concentrated within the approximately 3 km radial area around the KTPS and especially on downwind side (higher impact area). In the impact area, the particulate matter (PM10) ranged from 108 to 190.06 µg/m3, particulate matter (PM2.5) ranged from 63.71 to 125.85 µg/m3, The levels of sulphur dioxide (SO2), nitrogen dioxide (NO2) and carbon monoxide (CO) were observed to be below NAAQS standards. However, the baseline status of SO2 in non-impacted area was observed to approach the threshold level to NAAQS standard. Particulate pollution at all sites and SO2 in impact zone were above WHO standard. National Air Quality Index (AQI) indicated Poor to Very Poor air quality in impact zone and Satisfactory to Moderate air quality at other monitoring stations. The KTPS requires implementation of efficient air pollution control measures.
