Dr Anju Goel, Associate Director, Air Quality Research Division, The Energy and Resources Institute (TERI) said these numbers could be representative of AQI values for PM2.5 and PM10 concentrations and are wrongly written as PM2.5 and PM10 levels. She explained, for instance if Mayur Vihar had a PM2.5 AQI of 221 and a PM10 AQI of 207, that would make sense — but it should be reported as AQI, not µg/m³. When presented as pollutant concentrations (µg/m³), those numbers are misleading and

Delhi's pollution pattern is no longer a mystery. It's a challenge well understood. Decades of research have consistently identified both its sources and its seasonal behaviour. Studies by IIT Delhi, TERI, and the System of Air Quality and Weather Forecasting and Research (SAFAR) have shown that air quality deteriorates sharply in October and November due to a combination of anthropogenic and meteorological factors.

The reduction in fire count during the period may be attributed to crop damage due to massive flood in the region. However, largescale awareness and initiatives related to crop residue management in both Punjab and Haryana might have led to the reduction in the crop residue burning events, said Dr Arindam Datta, Senior Fellow, TERI.
