Delhi’s NO2 levels 3 times the safe limit at hot spots

Nitrogen dioxide levels in Delhi have soared to three times the national safe limit, with measurements reaching 240µg/m³ at IGI Airport, exacerbating the city's air quality crisis alongside hazardous PM2.5 and PM10 levels. Key sources include vehicular emissions and industrial activities. Prolonged exposure raises health risks, while data gaps question the accuracy of air quality readings, highlighting urgent environmental concerns.
