Delhi’s air quality has suffered more in the first two weeks of August as compared to the same time last year, data collated by the Central Pollution Control Board (CPCB) shows. Moreover, Delhi is the second most polluted city among the neighbouring ones including Gurgaon, Faridabad, Agra and Ghaziabad.
However, Ghaziabad, where air quality monitoring was started only this year, is the most polluted with an average air quality of 126.7 as compared to Delhi’s 112.
Delhi and surrounding areas see the best air quality in the months of July and August because of the rain.

In monsoon months, however, the pollution in these cities goes down considerably. Delhi, though, still sees higher pollution as compared to the others.
Rainfall has the capability to dissolve several pollutants and wash away particulate matter and dust and that is one of the reasons behind lower air pollution levels.
