Delhi's air quality plunged to 'Unhealthy' category on Thursday. The national capital and nearby regions were blanketed under dust and smog as the air quality got worse.

The Centre-run System of Air Quality and Weather Forecasting and Research (SAFAR) advised people to avoid their morning walks or any other outdoor activities. The poor air quality has led to an increase in respiratory difficulties, cough and eye irritation amongst people.

"The pollution has increased in the past three days. I am feeling very suffocated. There is so much haze everywhere. I will soon start wearing an anti-pollution mask during morning walks. The government must do something to combat air pollution in the capital,"  Ravinder Kumar, a local resident told ANI.

As per the air quality index (AQI), the particulate matter (PM) 2.5 which is the major pollutant reached 229 whereas PM 10 was recorded at 229; both in 'Unhealthy' category.

Particulate matter also known as particle pollution or PM is microscopic solid or liquid matter suspended in the air. It is made up of several components comprising metals, soil, acids such as nitrates and sulphates, organic chemicals and dust particles.

The air quality in several parts of Delhi-National Capital Region (NCR) slipped into the "very poor" category on Wednesday morning with concentration of particulate matter less than 10 micrometers in diameter being the main pollutant.

The national capital's overall air quality index (AQI) also bordered along "very poor" level on Wednesday. It stood at 299 whereas, the national capital's AQI was 270 on Tuesday as its PM level shot up twice the safe limit.

Seventeen of the 37 air quality monitoring stations in the national capital recorded the overall AQI in the "very poor" category, according to data of the Central Pollution Control Board.

The AQI at Mundka, Dwarka Sector 8, Delhi Technological University, Anand Vihar, Wazirpur, Rohini, Bawana, Ashok Vihar, Nehru Nagar and Jahangirpuri was 368, 362, 355, 328, 323, 323, 320, 319, 319 and 318.

Other areas that experienced very poor air quality included Alipur (314), Narela (312), Vivek Vihar (311), Sirifort (309), CRRI - Mathura Road (304), Okhla Phase 2 (303) and ITO (302).

The neighbouring areas of Ghaziabad (337), Loni Dehat (335), Noida (318) and Greater Noida (308) also recorded a spike in pollution levels.

An AQI between 0 and 50 is considered 'good', 51 and 100 'satisfactory', 101 and 200 'moderate', 201 and 300 'poor', 301 and 400 'very poor', and 401 and 500 'severe'.

The Centre-run System of Air Quality and Weather Forecasting and Research (SAFAR) had on Tuesday noticed an 'increasing trend" in stubble burning incidents in neighbouring states and predicted that the share of crop residue burning in Delhi's PM2.5 concentration would be around 6 per cent on Wednesday.

The Delhi government had also shared pictures and data from NASA that showed large-scale stubble burning in areas surrounding Delhi.

On Tuesday, Delhi Environment Minister Kailash Gehlot also wrote to Union Minister for Earth Sciences Harsh Vardhan requesting access to SAFAR's data so that the administration could take immediate corrective measures to curb pollution.

Earlier, the Supreme Court-mandated Environment Pollution (Prevention and Control) Authority had said that local sources of pollution, including stack emissions, dust, and burning of plastic and rubber waste, were the primary reason for deteriorating air quality in Delhi-NCR.
