In the World Air Quality Report 2022, India ranked 8th in terms of average PM2.5 concentration globally with a value of 53.3 μg/m3, and a number of the 7 most polluted cities are located in India out of 50 top cities. The presence of poor air quality in mining cities has a positive relationship with mining activities, and this scenario persists in different cities of Jharkhand state. In this study, we draw the API (Air Pollution Index) with the help of the fuzzy analytical hierarchy process (FAHP) across the state of Jharkhand by considering parameters such as CO, O3, NO2, SO2, and PM10 and the relationship between Sentinel 5P aerosol optical depth (AOD) and CPCB published ground data of PM10 (i.e., monthly and seasonal) was also explored. The outcome depicts that a high concentration of API is dominant along the north-eastern part of the state due to the intensive mining activity along this part of the state, and the trend of concentration of PM10 in the air is continuously increasing from 2012-2018 as per the GOJ (Government of Jharkhand) report. This study will give insight into the pollution scenario in the mining-dominated state of Jharkhand, and along with that, it will also spread awareness of the impact of mining activities on the atmosphere.
