Even with intermittent rainfall, pollution levels in Thane witnessed a noticeable spike during Lakshmi Puja and Diwali celebrations, according to data from the Thane Municipal Corporation (TMC). The city’s Air Quality Index (AQI) increased from 141 before Diwali to 157 during the festival period, moving closer to the “moderate to poor” category.
🌫️ Increase in Air Pollution Levels
As per the official TMC report, there was an 11.1% increase in air pollution levels on Lakshmi Puja day compared to the pre-Diwali period. The concentration of particulate matter (PM10) — one of the major pollutants that affect respiratory health — rose to 139 µg/m³.
Environmental experts attribute this rise mainly to the bursting of firecrackers, vehicle emissions, and increased local activity during the festive season. Even light rainfall failed to significantly bring down the pollution levels.
🔊 Noise Pollution Also on the Rise
In addition to air pollution, the report also revealed a 3.2% rise in noise levels during Diwali compared to regular days. The increased use of loud firecrackers and amplified music during celebrations contributed to this uptick.
🌱 TMC’s Appeal for Greener Celebrations
The Thane Municipal Corporation’s Environmental Department has urged residents to be more conscious of their environmental impact during festive celebrations.
“We urge citizens to take conscious efforts to reduce their environmental footprint during festivals. Green fireworks are a step in the right direction,” said Manisha Pradhan, Chief Environmental Officer, TMC.
💨 Why This Matters
Prolonged exposure to elevated AQI levels can affect individuals with respiratory conditions, children, and the elderly. Authorities recommend minimizing outdoor activities during high-pollution hours and promoting eco-friendly celebrations to maintain the city’s air quality.
