Delhi's air quality very poor MeT conditions slightly favourable for pollutant dispersion

Delhi's air quality very poor MeT conditions slightly favourable for pollutant dispersion

In some parts of Delhi, pollution levels hit 654 on Monday, among the worst recorded this year, and visibility in some parts of the city was just 200 metres, the weather department said.

The air quality levels have worsened in the national capital region for the fourth consecutive day and the alarming situation could prompt the return of the odd-even vehicle scheme.

The air quality of the Capital turned "severe" on Saturday and recorded its second-highest pollution level of the year on Sunday with an AQI of 450.

"In October and November, there are around 20-25 days when pollution level increases in Delhi due to stubble burning (in neighbouring states)". Air quality in Faridabad and Noida was also recorded in the "severe" category. Thirty areas in the city recorded "severe" air quality while it was "very poor" in five areas, it said.

The Central Pollution Control Board (CPCB) data showed the overall air quality index (AQI) at "very poor" level of 396, while the Centre-run System of Air Quality and Weather Forecasting (SAFAR) showed an AQI of 369 which too falls in the "very poor" category.

According to sources, Delhi's air pollution levels have constantly been on the rise since the festival of Diwali.

The "severe" quality of air was attributed to wind speed and other meteorological factors remaining "highly unfavourable" for dispersion of pollutants.

The air quality in nearby Ghaziabad was "severe" in the afternoon but improved to "very poor" by the evening.

The index was 5500 sqm/second on Wednesday, the IITM said.

"Concerned police department to strictly ensure that non-destined heavy duty vehicles travel through eastern and western peripheral expressways", the Supreme Court-appointed Environment Pollution Control Authority said.

A Delhi government official blamed the pollution for lighter-than-usual traffic on already holiday-thinned streets, while a Delhi airport official said some domestic and global flights were delayed for up to two hours due to poor visibility.

The AQI recorded 217 with PM (particulate matter) 2.5 at 557 and PM (particular matter) 10 at 747.

"There is a lack of political will to take required measures on a sustained basis to contain pollution levels", said Sunil Dahiya, a senior campaigner with Greenpeace India. The agency has advised people to avoid all outdoor activities, such as taking walks.

The Indian Institute of Tropical Meteorology said biomass burning is also contributing to the spike in PM2.5 concentration.

Delhi's air quality remained in the "severe" category for the fourth consecutive day on Tuesday as meteorological conditions continued to be unfavourable for dispersion of pollutants, authorities said.
