Ghaziabad air quality remained “severe” for the sixth day in a row while it was “very poor” in Noida and Faridabad and “poor” in Gurugram, according to a government agency data on Wednesday.

Presence of pollutant PM 2.5 and PM 10 also remained high in the five immediate neighbours of Delhi, according to the air quality index (AQI) maintained by the Central Pollution Control Board (CPCB).

According to the index, an AQI between 0 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 average 24-hour AQI at 4 pm on Wednesday was 418 in Ghaziabad, 394 in Noida, 404 in Greater Noida, 395 in Faridabad and 296 in Gurugram, according to CPCB’s Sameer app.

On Tuesday it was 424 in Ghaziabad, 407 in Noida and 405 in Greater Noida, 382 in Faridabad and 347 in Gurugram.

On Monday it was 438 in Ghaziabad, 422 in both Noida and Greater Noida, 388 in Faridabad and 357 in Gurugram.

On Sunday it was 428 in Ghaziabad, 402 in Noida, 396 in Greater Noida, 392 in Faridabad and 325 in Gurugram.

The CPCB states that an AQI in the “poor” category causes breathing discomfort and “very poor” may cause respiratory illness on prolonged exposure, while “severe” affect even healthy people and seriously impacts those with existing diseases.

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