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
