Delhi recorded its most polluted Diwali in five years, with the city's Air Quality Index (AQI) soaring to 376, placing it in the 'very poor' category and raising fresh concerns over the capital's deteriorating air quality.
The sharp deterioration in air quality comes amid concerns over the impact of firecracker emissions, vehicular pollution and unfavourable weather conditions. The pollution spike has once again brought the national capital's annual battle against toxic air into sharp focus.
Air Quality Deteriorates Sharply
An AQI reading of 376 indicates a significant concentration of pollutants in the atmosphere, posing health risks, particularly to children, elderly people and those suffering from respiratory and cardiovascular ailments.
The 'very poor' category corresponds to AQI levels between 301 and 400. Prolonged exposure to such air can cause respiratory discomfort even among otherwise healthy individuals, while people with pre-existing health conditions face greater risks.
The latest reading marks a worrying setback in the capital's efforts to contain pollution during the festive season.
Firecrackers Add to Pollution Concerns
Diwali celebrations, traditionally associated with fireworks, often lead to a sudden increase in particulate matter and other harmful pollutants. Firecracker emissions release fine particles and toxic gases, which can remain suspended in the atmosphere, particularly when weather conditions restrict their dispersion.
The impact is often compounded by existing sources of pollution, including traffic emissions, construction dust and industrial activity.
Health Risks Raise Alarm
The deteriorating air quality has renewed concerns about the health implications of prolonged exposure to polluted air. Fine particulate matter, particularly PM2.5, can penetrate deep into the lungs and enter the bloodstream, increasing the risk of respiratory and cardiovascular complications.
Health experts generally advise residents to minimise prolonged outdoor activities when pollution levels remain elevated, especially during early morning and late evening hours.
Delhi's Pollution Battle Continues
The latest pollution spike highlights the persistent challenge of improving Delhi's air quality despite recurring restrictions and pollution-control measures.
With the AQI touching 376, the capital's Diwali celebrations have once again coincided with a severe environmental crisis, underscoring the urgent need for sustained action against the multiple sources of air pollution.
