چکیده
In recent years, air pollution in Chennai city India causes some health effects. This study examines the spatial-temporal characteristics of ambient quality five stations Adyar, Anna Nagar, Kilpauk, Nungambakkam and Thiyagaraya Nagar from 2017 to 2022. The surface level aerosol pollutants like particulate matters (PM 2.5 & PM 10 ) gaseous Sulfur dioxide (SO 2 Nitrogen (NO were obtained Tamilnadu Pollution Control Board (TPCB) for years which includes pre-COVID, during Post- COVID - period. results showed that fine matter coarse ), decreased by 19.49% 31.91% respectively pollutant SO2 NO2 slightly increased 7.84% 1.2 % 2021 as compared with 2017.The exceeded National Ambient Air Quality Standards (NAAQS) well WHO recommended Guidelines 2017-2019(Pre-COVID) low 2020-2021(During Post-COVID). average Index (AQI), calculated date 120(2018-2019) 93(2020-2021) city. AQI /PM highest winter lower summer. PM10 was primary pollutant, followed NO , SO spatial temporal variations. proportion but NO2. offers useful data resources further research on Chennai's quality.
