Delhi triggers GRAP Stage-1 as air turns toxic ahead of Diwali

National News: Delhi’s air turned toxic earlier this week as pollution levels crossed the safety threshold, forcing authorities to act. The Commission for Air Quality Management (CAQM) ordered the immediate rollout of Stage-1 measures under the Graded Response Action Plan, known as GRAP. This step was triggered when the city’s Air Quality Index reached 211, which falls into the “poor” category. Officials confirmed stricter monitoring of open waste burning, dust control measures, and better checks on construction activity as part of the first-stage response.

AQI slips beyond safe limit

According to data from the Central Pollution Control Board, the average AQI in Delhi touched 211 by Tuesday evening. This was the first time since June that the national capital recorded such poor readings. Experts attribute the rise in pollution to slower wind speed and a drop in night temperatures, which trap pollutants closer to the ground. With the festival season beginning, environmental scientists have warned that conditions are unlikely to improve anytime soon.

Pre-Diwali pollution levels rise

The worsening air quality comes just days before Diwali, a period that traditionally witnesses high levels of pollution. Every year, the bursting of firecrackers during the festival combines with already existing emissions, creating a toxic cloud over the capital. This year too, forecasts suggest that the AQI will worsen further and may touch the “very poor” range. Authorities have urged residents to avoid crackers and reduce emissions, but enforcement continues to remain a challenge.

Farm fires add to Delhi’s woes

One of the biggest contributors to Delhi’s annual pollution crisis remains farm stubble burning in neighbouring states like Punjab and Haryana. Satellite images and on-ground data show rising incidents of crop residue fires, which add to the city’s already fragile air quality. Combined with vehicular emissions and industrial smoke, the situation creates a deadly cocktail of pollutants. Experts say farm fires could peak around Diwali, leaving Delhi residents gasping for clean air.

Forecast shows no immediate relief

The Centre’s Air Quality Early Warning System has predicted that Delhi’s air will remain in the “poor” to “very poor” range over the coming week. Meteorologists explain that stagnant wind conditions are preventing pollutants from dispersing, while cooler temperatures lock smoke and dust close to the ground. Unless there is a significant change in weather, such as rain or stronger winds, the city will continue to face worsening air quality.

Public health concerns grow

Doctors and health experts are already warning of a rise in respiratory illnesses, especially among children, the elderly, and those with existing conditions like asthma. With toxic pollutants in the air, hospitals are preparing for an increase in patients complaining of breathlessness and eye irritation. Authorities have urged citizens to wear masks outdoors, limit physical activities, and avoid early morning walks, when pollution is most concentrated.

The road ahead for Delhi

While Stage-1 of GRAP has been imposed, many believe it is only the beginning of a longer battle. If air quality worsens, tougher restrictions such as a ban on diesel generators, limits on construction, and restrictions on vehicle movement may follow. Environmental activists argue that unless systemic solutions are found, Delhi will continue to repeat this annual cycle of crisis. For now, citizens are bracing for another Diwali under a thick cloud of smog.
