Haze engulfs Delhi-NCR as air quality reaches 'hazardous' level

A thick blanket of haze continued to envelop Delhi and parts of the National Capital Region (NCR) on Thursday with the air quality remaining in 'poor' to 'hazardous' category.

Visuals from Rajpath in Central Delhi showed dust and haze hovering over the sky with visibility remaining very low.

In the morning on Thursday, Air Quality Index at RK Puram, Mandir Marg, Dwarka, Punjabi Bagh and ITO monitoring stations remained in 'hazardous' category. The RK Puram monitoring station showed that PM10 (particulate matter 10-particles with a diameter less than 10mm) had reached the highest level of 999. PM2.5 was recorded 199 around 8 am.

On Mandir station, while PM2.5 was 190, PM10 was seen at 770.

The Air Quality in Lodhi Road area also remained in poor' category with PM10 spiking to 262.

The Environment Ministry on Wednesday said that the dusty conditions were a fallout of dust storms from Rajasthan. It predicted that the condition is likely to prevail over the next three days.

High pollution levels in Delhi are mainly due to the dust storms from the desert state, the ministry said after air quality in the national capital deteriorated beyond "severe" level on Wednesday.

It has also alerted major construction agencies, municipal corporations and Delhi Pollution Control Committee (DPCC) to ensure water sprinkling, and asked Delhi's Chief Secretary to issue appropriate instructions in the matter to the agencies concerned.

The Central Pollution Control Board (CPCB) also convened an urgent meeting of the Task Force regarding implementation of Graded Response Action Plan (GRAP) today and issued necessary directions to contain local dust sources.

The air quality in Delhi deteriorated beyond the "severe" level because of a ground-level dust storm in western India which increased coarser particles in the air, the Central Pollution Control Board data showed.

The CPCB said the pollution of this season was very different from that of last year. In November last year, both PM2.5 and PM10 had spiked which was posing serious health hazard. However, the current increase in levels of pollution is mainly due to drastic increase in coarse particles in air which has caused a spike in PM10 level but PM2.5 is not as high as that of last year.
