Notes:

Ammonia (NH3) is another gaseous pollutant that is monitored, whose 24-hour exposure limit is 400 ug/m3.

The average 24-hour range of NH3 as of 1pm on Friday at the three highly polluted areas in Delhi was between 9 and 28 ug/m3, as per CPCB data.
The EPA states that ammonia occurs naturally in air, soil and water, and is used as an agricultural fertiliser and in cleaning products.
Short-term inhalation of high levels of ammonia can cause irritation and serious burns in the mouth, lungs and eyes.
Chronic exposure to airborne ammonia can increase the risk of respiratory problems, including impaired lung function.
