Most of them (82.2 per cent) knew that air pollution has an impact on their health, while 38.8 percent said they or their family members visited the hospital due to respiratory discomfort in last one year.

However, only 31.4 per cent were aware of any public health emergency declared by the Delhi government, the survey said.

More than 80 per cent of the participants did not know what air quality index is or the difference between PM10 and PM2.5.?PM refers to particulate matter.

The difference is that PM10 is fine particles of 10 microns and below in diameter and PM2.5 is 2.5 microns and below.

The findings showed 78.9 per cent of the people do not know about the National Clean Air Programme, which proposes a framework to achieve a national-level target of 20-30 per cent reduction of PM2.5 and PM10 concentration between 2017 and 2024.
