Bhogi Pandigai Push Chennai’s Air Quality Into ‘Unhealthy’ Zone, AQI Hits High Levels

Chennai is witnessing a rise in air pollution as Bhogi festival bonfires fill the city with smoke, causing visibility issues and health concerns. Data from the Tamil Nadu Pollution Control Board (TNPCB) at 7 a.m. revealed particulate levels above normal in several areas, with the resulting haze affecting both residents and traffic. The thick smog has already led to the cancellation of eight flights at Chennai Airport.

Residents across the city are following the traditional practice of burning old household items to mark Bhogi, the first day of the Pongal festival, celebrated on the last day of the Tamil month of Margazhi. The custom, often associated with the saying "பழையன கழிதலும், புதியன புகுதலும்," symbolises the disposal of the old to welcome the new. Children can be seen beating drums and joining street gatherings, adding to the festive atmosphere.

However, environmental concerns are mounting as many bonfires include mixed waste such as plastics and synthetic materials, rather than only natural household articles. Despite repeated appeals from authorities to avoid burning tyres, tubes, and plastics, smoke continues to linger over several neighbourhoods, exacerbating pollution levels.

Air Quality Index Highlights Poor Conditions

Monitoring stations across Chennai recorded a significant rise in particulate matter. The Air Quality Index (AQI) readings at 7 a.m. were as follows:

Kummidipundi - 196

Manali - 144

Kodungaiyur - 123

Arumbakkam - 117

Gandhi Nagar (Ennore) - 114

Perungudi - 103

Velachery - 76

Royapuram - 64

With an AQI above 100 considered unhealthy for sensitive groups, these readings indicate that much of Chennai is experiencing poor air quality. Motorists report difficulties due to reduced visibility as smoke from bonfires combines with morning fog, creating dense patches of haze in residential areas.

Impact on Health and Transport

The pollution spike is not only affecting daily commuters but has also disrupted air travel. Chennai Airport officials confirmed that eight flights were cancelled due to low visibility linked to smoke and fog. Health experts warn that prolonged exposure to high particulate levels can aggravate respiratory issues, particularly among children, the elderly, and those with pre-existing conditions.

As Pongal celebrations continue across Tamil Nadu, Chennai faces the challenge of balancing traditional customs with environmental safety. Officials are expected to continue urging residents to adopt cleaner practices during festival observances to reduce both health risks and operational disruptions.
