With the coming of the festival of light, the entire state of Delhi is covered again by a lot of smog, which is also alarming about the pollution level. In recent days, the level of the Air Quality Index (AQI) has been slowly deteriorating, progressing towards the boundaries of the categories of poor, very poor, and severe in many places. The increase has been linked to a mixture of stubble burning in neighbouring states, vehicular emissions, low wind speeds, and lower temperatures, which hold the pollutants near the ground.

Recent reports depict smog blanketing wide areas of the city, such as the Anand Vihar and the Delhi-Noida Flyway, severing the sight and posing great health risks. As the Diwali festival nears, the government has put in place measures governed by the Graded Response Action Plan (GRAP), and people are urged to remain indoors, wear their masks and take precautionary measures to ensure that they are not exposed to poisonous air.

AQI Levels In Delhi And Delhi NCR:

  • Anand Vihar: AQI 426 (Severe)
  • RK Puram: AQI 322 (Very Poor)
  • Bawana: AQI 303 (Very Poor)
  • Jahangirpuri: AQI 314 (Very Poor)
  • Ghaziabad: AQI 324 (Very Poor)
  • Noida: AQI 298 (Very Poor)
  • Gurugram: AQI 342 (Very Poor)
  • Delhi (Overall): AQI 254 (Poor)

Reason Of Depleting Air Quality

  • Stubble Burning: Crop residues in Punjab and Haryana are burnt, causing enormous amounts of smoke and particulate matter.
  • Vehicular Emissions: Millions of vehicles are on Delhi's roads, and therefore, emissions are a major contributor to pollution.
  • Construction Dust: Construction and road dust contribute to the degree of particulate matter.
  • Weather Conditions: Low wind and lower temperature helps to keep the pollutants near the ground.
