Air Pollution Rises in Kolkata Due to Kali Puja Firecrackers, Environmentalists Concerned

In Kolkata, the skies have been filled with the sound and smoke of firecrackers for several days in celebration of Kali Puja, leading to a significant rise in air pollution across the city. According to data from the Central Pollution Control Board, air quality in various parts of the city has been marked as “poor.” As of Saturday morning, the air quality index in several areas exceeded 200, which experts warn is a severe risk to public health.
On Saturday morning, the air quality index in Ballygunge was 288, in Jadavpur it reached 210, and near Rabindra Bharati University it was 211. In these areas, particulate matter (PM2.5) reached a concentration of 500 micrograms per cubic meter, classified as “poor.” Generally, an air quality index of 201-300 is considered “poor.” However, areas around Fort William, Rabindra Sarobar, and Victoria Memorial showed relatively better air quality, with levels under 200.
The chairman of the Pollution Control Board, Kalyan Rudra, commented, “Stricter police monitoring is needed to prevent excessive firecracker usage.” He also noted that air pollution levels have slightly reduced compared to 2023, yet residents need to be more responsible. The festive season brings increased respiratory risks, especially for the elderly and children.
The pollution levels in Delhi are also concerning. On Friday night, particulate matter in Anand Vihar, the airport area, Rohini, and Lodhi Road reached close to 500 micrograms per cubic meter. Environmentalists state that while a concentration of up to 50 micrograms per cubic meter is considered good, levels above 400 indicate severe pollution.
Although only approved firecrackers are legally allowed in Kolkata, there are concerns that administrative efforts to control noise pollution have been insufficient. Loud crackers continued to be used across the city even after Diwali, further contributing to air and noise pollution. Environmentalists are urging the administration and citizens to take more responsible measures to curb pollution in the city.
