Air quality remained “poor” in Noida, Greater Noida, Ghaziabad, Gurgaon and Faridabad in the National Capital Region (NCR) on Sunday, a government agency said.

The presence of PM 2.5 pollutants also remained high in Delhi’s five immediate neighbors, according to the Air Quality Index (AQI) maintained by the Central Pollution Control Board (CPCB).

According to the index, an AQI between zero and 50 is considered ‘good’, 51 and 100 ‘satisfactory’, 101 and 200 ‘moderate’, 201 and 300 ‘poor’, 301 and 400 ‘very poor’ and 401 and 500 ‘severe ‘.

The 24-hour average AQI at 4 p.m. Sunday was 242 in Gurgaon, 234 in Faridabad, 288 in Ghaziabad, 273 in Noida and 270 in Greater Noida, according to the CPCB’s Sameer app.

On Saturday, there were 256 in Gurgaon, 246 in Faridabad, 238 in Ghaziabad, 231 in Noida and 228 in Greater Noida.

The CPCB states that an AQI in the “poor” category can cause respiratory discomfort to most people with prolonged exposure, while in the “very poor” zone it can cause respiratory illness with prolonged exposure.

The average AQI last Sunday was 448 in Ghaziabad, 441 in Noida, 417 in Greater Noida, 425 in Gurgaon and 414 in Faridabad.

The AQI of each city is based on the average value of all the stations there. Noida, Faridabad, Ghaziabad have four seasons each, while Gurgaon has three and Greater Noida two, according to the app.
