Delhi Pollution highlights: Once again Delhiites woke up under a thick cover of smog on Tuesday morning. Two days after Sri Lankan cricketers took to the field in Firoza Kotla stadium wearing anti-pollution masks, the air in the national capital turned fouler today with a sharp rise in the level of particulates since morning. The concentration of the most prominent pollutants, PM 10 and PM 2.5, reached ‘severe’ and ‘very poor’ category, respectively in Delhi’s Lodhi Road area. Pollution in the national capital region still remains a bouncer for policy. The area around India Gate also landed to ‘poor’ category on Air Quality Index. November witnesses extremely high levels of pollution as smoke from paddy residue burning reaches the city, aggravating the situation. However, there are phases, when such spikes are seen even during December and January, mostly due to rapid drop in temperature and high moisture content, factors that trap particulates near the surface. According to an IIT-Kanpur study, the sources of PM2.5 and PM10 during the winter months are: secondary particles like nitrates (25-30 per cent), vehicles (20-25 per cent), biomass burning (17–26 per cent), municipal solid waste burning (9-8 per cent) and to a lesser extent soil and road dust. This blog will keep track of latest developments on air pollution and its adverse effects on Delhi through the day:

9:10 pm: Pollution is considered severe plus or emergency when readings of PM2.5 and PM10 cross 300 and 500 ug/m3, respectively. The corresponding prescribed standards are 60 and 100.

8:45 pm: According to the Central Control Room for Air Quality Management of the CPCB, the concentration of the most dominant pollutants, PM2.5 and PM10, were 261 and 438 ug/m3 around 5 pm.

8:15 pm: The concentration of NO2 breached the 24-hour safe limit of 80 micrograms per cubic metre (ug/m3) in areas like Dilshad Garden, ITO, Mandir Marg, Anand Vihar and R K Puram.

7:30 pm:  The United Nations marked the day as the first international smog day. It is a moment to remember all of the people who have died prematurely, and avoidably, because of the air pollution, the United Nations Environment Programme (UNEP) said in a statement.

7:15 pm: Air quality in Delhi, ‘very poor’ since November 23, remained unchanged today, with high-level of nitrogen dioxide (NO2) across residential areas heightening the toxicity of the haze.

6:45 pm: Information Commissioner Yashovardhan Azad had pointed out that in spite of specific queries with respect to the PUC certificates and also marking the RTI query correctly to the branch, no effort was made to attend to the query in the manner envisioned by the RTI Act.

The green panel was also irked by authorities for conducting the third Test between Sri Lanka and India yesterday which was disrupted due to the choking smog.

2: 10 pm: The tribunal, however, directed the government to file the report within the next 48 hours. “Where is your action plan? Why have you not submitted it? What can we do if you keep on changing everybody? It’s not our problem if people don’t want to stick to you.”  “You keep on doing meetings but tell us a single action or step you have taken in the last four days to combat air pollution,” the bench said.

2: 01 pm: A bench headed by NGT Chairperson Justice Swatanter Kumar took exception over the failure of the AAP government to file the report despite its specific order on Monday. During the hearing , the Delhi government said it needed more time to file the action plan as the chief secretary and environment secretary have been recently changed.

Ghaziabad, in fact, has been severely polluted for a week now. The concentration of PM 2.5 at 7 pm on Monday was 218 µg/m3. According to the forecast, the PM 2.5 concentration on Tuesday would be at 227 µg/m3, and is expected to be 236 µg/m3 on Wednesday. The prescribed standard for PM 2.5 is 60 µg/m3.

11: 59 am: Smog during the winter in Delhi-NCR is a curse for people, especially for those who want to fly-in or fly-out of the national capital. Train and flight services get hit severely by this.
