On Monday, Anand Vihar recorded an AQI of 318, the Delhi Technical University registered 288, ITO recorded 253 and Jahangirpuri recorded an AQI of 311, according to the CPCB website.

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

Delhi's neighbouring regions of Faridabad and Gurugram both recorded poor air quality.

The PM10 level (presence of particles with diameter less than 10 micrometres) in Delhi stood at 205 and the PM2.5 level was recorded at 106, according to the data.

Authorities apprehend further deterioration of air quality in the coming days.

A slew of measures are being taken by the Central Pollution Control Board (CPCB) to fight pollution during the winter season, when the air quality in Delhi is generally on the poorer side.

Meanwhile, recent satellite images from NASA show that farmers in Punjab and Haryana started burning crop residue earlier this month.

NASA, on its official website, stated that burning of crop residue in Punjab and Haryana has increased significantly over the past 10 days in and near Amritsar, Ambala, Karnal, Sirsa and Hisar.

Burning of paddy straw every year during October and November, and wheat straw during April in Punjab and Haryana are the major contributors to air pollution in Delhi-NCR. In Delhi, it mixes with fog and creates a toxic smoggy winter every year.

The CPCB said an emergency action plan kicked in Monday to combat air pollution.
