Mon Nov 18 14:15:30 UTC 2024: ## Delhi Chokes Under Severe Air Pollution; Schools Go Online

**New Delhi, November 18** – Delhi is grappling with its worst air pollution episode in recent years, with air quality index (AQI) levels reaching “severe plus” on Monday, prompting the implementation of the strictest measures under the Graded Response Action Plan (GRAP). At 6 pm, the Central Pollution Control Board (CPCB) recorded an AQI of 494, exceeding 400 across all 38 monitoring stations.

Experts are calling this one of the most severe November pollution events in recent memory. Sunday’s average pollution levels were the worst for October-November since 2022, with PM2.5 levels exceeding WHO standards by more than 20 times (reaching 354 micrograms per cubic metre). Dwarka and Najafgarh recorded the highest pollution levels, reaching an AQI of 500.

Environmental analyst Sunil Dahiya attributed the crisis to insufficient action on persistent pollution sources, increased stubble burning, and unfavorable meteorological conditions. Data shows that Sunday’s 24-hour average PM2.5 level (429 micrograms per cubic metre) was the highest since November 2021.

In response, the Delhi government has implemented Stage 4 of GRAP, halting most construction and demolition activities and restricting the entry of older diesel vehicles. All schools, except those for classes 10 and 12, have shifted to online classes until further notice.

The India Meteorological Department (IMD) has issued a yellow alert, forecasting moderate to dense fog for the next few days, hindering pollutant dispersal. The IMD also reported significantly reduced visibility due to dense fog in several areas of Delhi.

The IITM predicts “severe” or “very poor” air quality for the next six days. The situation underscores the urgent need for sustained efforts to combat air pollution in the capital.
