As temperatures rise, ozone levels are steadily going up in Delhi. A dangerous gas, also called sunburn for the lungs, it is formed when NOx (nitrogen oxides) and VOCs (volatile organic compounds) emitted by industries and vehicles react with sunlight under high temperature. It is so toxic, it is measured on an hourly basis instead of 24-hourly basis, as even minute quantities act like sandpaper on the inside of the lungs and lead to asthma attacks, say experts.

This week, the Central Pollution Control Boards (CPCB) National Air Quality Index (NAQI) recorded Ozone as the primary pollutant in Delhi on three days May 4th, 2nd and 1st. This is when, generally, only PM (Particulate Matter) 10 and PM 2.5 emerge as the primary pollutants in the national Capital on most days, besides Nox and CO (Carbon Monoxide) rarely.

 In entire April, ozone (O3) had figured as a primary pollutant on five days only 1st,7th,8th,10th and 24th. While in January, it exceeded its permissible level (180 ug/m3) just once at RK Puram and Ghaziabad, it increased to seven days at Pusa Road monitoring station, in February. The highest this year in Delhi, in March, Punjabi Bagh recorded 192 ug/m3 of ozone on March 17.

Experts like Anumita Roychowdhury, head of Clean Air Campaign at think tank CSE, say, The problem will only get worse as summer progresses if corrective steps are not taken soon.”
