Delhi AQI hits ‘Severe’: Low visibility, primary schools go online as GRAP-3 kicks in

Delhi’s air quality remains in the “severe” category, as thick smog blankets the city on Friday, November 15. The Air Quality Index (AQI) hit dangerous levels across several areas, with Anand Vihar recording an AQI of 441 at 6 a.m. on Thursday. Other locations, including Bawana (455), Dwarka Sector 8 (444), and Jahangirpuri (458), reported some of the worst pollution levels, all above 400, classified as “severe.”

The Central Pollution Control Board (CPCB) responded by activating Stage 3 of the Graded Response Action Plan (GRAP). Starting at 8 a.m. Friday, these measures include a ban on construction and demolition work and restrict the movement of BS-III petrol and BS-IV diesel vehicles in Delhi and the National Capital Region (NCR). Authorities are enforcing these restrictions in Delhi and nearby areas to curb pollution levels.

In response to the escalating health risks, the Delhi government suspended physical classes for primary schools. Until air quality improves, students in affected areas will attend classes online.

The air quality in Delhi worsens each winter, with pollution sources compounding the crisis. Vehicular emissions, industrial activities, and dust from construction contribute significantly. However, stubble burning in neighboring states also remains a major factor. Data shows that this practice adds to the already high pollution load in Delhi, with fires increasing significantly this season.

GRAP, introduced by CPCB, serves as a response framework for pollution emergencies. It includes four stages: “poor,” “very poor,” “severe,” and “severe plus,” with each stage triggering specific actions. Stage 3, now active, aims to reduce immediate pollution impacts by limiting activities that raise dust and emissions.

Delhi’s air quality hit “very poor” levels by October 30, steadily worsening to the “severe” category on Wednesday. Authorities closely monitor AQI data, with 27 of Delhi’s 39 air quality stations currently reporting “severe” conditions.

Experts urge immediate action to protect public health. Medical professionals recommend minimizing outdoor activities, especially for children, the elderly, and those with respiratory conditions. Authorities are also coordinating with NCR states to enforce anti-pollution rules more rigorously.

With pollution levels expected to persist, the government and residents await improved air quality as authorities work to implement effective countermeasures.
