Correct Answer - Option 2 : PM particle, Carbon monoxide and oxides of Sulphur
Critical air pollutants are
- particulate matter (PM) – one bin with all PM below 10μm (PM10) and one bin with all PM below 2.5μm (PM2.5)
- sulfur dioxide (SO2)
- carbon monoxide (CO)
- nitrogen oxides (NOx) – nitric oxide (NO) and nitrogen dioxide (NO2)
- ozone (O3)
And on the other side, we have the greenhouse gases (GHGs) like carbon dioxide (CO2), which also has an impact on health, but more decisively linked to climate change.

In cities like Delhi, Mumbai and other major air pollutants are PM particle, Sulphur dioxide and carbon monoxides which is due to constant vehicular movement and construction.
