Delhi-NCR faces pollution challenges as Diwali approaches, and the air quality in the region is already showing signs of decline. On Sunday, Delhi’s Air Quality Index (AQI) was around 177, which falls between the ‘moderate’ and ‘poor’ categories. Levels of PM2.5 reached 155, while PM10 was recorded at 177, indicating rising concentrations of harmful particles in the air.
Several areas across the National Capital Region (NCR), including Noida and Gurugram, have experienced a rapid drop in air quality over the last week. On October 11, Delhi’s AQI rose to 193, a sharp jump from the previous week’s average of 120. Experts from the India Meteorological Department (IMD) and the Early Warning System warn that air quality could slip into the ‘poor’ category by mid-October. Slower wind speeds and falling temperatures are expected to trap pollutants closer to the ground, worsening the situation.
There are multiple reasons behind this increasing pollution. Low wind speed prevents pollutants from dispersing, while temperature inversion traps polluted air near the surface. Stubble burning in nearby states like Punjab and Haryana has resumed, pushing smoke and fine particles into Delhi’s air. Additionally, vehicle emissions continue to release harmful gases, and construction work adds large amounts of dust to the atmosphere. Experts also warn that the widespread use of firecrackers during Diwali will make the situation even worse. In previous years, air quality entered the ‘severe’ category immediately after the festival due to fireworks.
Medical experts are urging people to take precautions. Exposure to polluted air can cause breathing difficulties, eye irritation, and fatigue. Vulnerable groups, such as children, senior citizens, and people with asthma or heart disease, face higher health risks. To stay safe, experts advise limiting outdoor activities on high-pollution days, using air purifiers indoors, and wearing N95 masks when going outside.
Authorities are asking citizens to avoid using firecrackers during Diwali and to follow pollution-control measures strictly. They are also increasing checks on construction sites and vehicles to ensure compliance with emission regulations. Environmental groups have called for tougher action against stubble burning and better regulation of construction dust. They warn that without immediate steps, Delhi-NCR could face pollution levels as bad as, or worse than, last year’s post-Diwali crisis.
Pollution during the winter months is a recurring problem in Delhi-NCR. Every year, a combination of weather conditions, agricultural burning, vehicle exhaust, and festive fireworks leads to a significant decline in air quality. The situation highlights the urgent need for long-term solutions, such as cleaner public transport, improved waste management, and stricter enforcement of air quality laws.
In conclusion, Delhi-NCR faces pollution challenges as Diwali celebrations draw near, and collective action is more urgent than ever. By celebrating responsibly, reducing firecracker use, and supporting pollution-control efforts, people can help improve air quality. Protecting the air we breathe is essential not only for public health but also for the future of the city.
