ABSTRACT

 

Air pollution is an important and popular topic of concerns at ITO intersection in Delhi as health impact concerns have been raised caused by vehicle exhausts and industrial exhausts in recent years. Sulphur dioxide (SO2), nitrogen dioxide (NO2), carbon dioxide (CO2) and respirable suspended particulate matters (RSPM) are major air pollutants caused by the dominant usage of diesel, petrol and CNG fuels by vehicles and industries. These major air pollutants impose harmful impact on human health. In this study, the varying trends of ambient air quality and the levels of related air pollutants are analyzed based on the database monitored at Bahadurshah Jafar marg near ITO intersection, air quality monitoring station. Seasonal Autoregressive Integrated Moving Average (ARIMA) approach, implemented by Box
