Chennai witnessed a sharp rise in air pollution during Diwali celebrations as fireworks pushed pollution levels to extreme levels in several parts of the city. Live air quality monitoring apps reportedly recorded an Air Quality Index (AQI) reading of 1,123.
According to the reported readings, PM2.5 levels reached 638 micrograms per cubic metre (µg/m³), while PM10 levels touched 768 µg/m³. The sudden rise was linked to widespread firecracker use during the festival.
The pollution spike occurred between spells of rain, which did not prevent fireworks-related pollution from affecting the city’s air quality. Several residents shared warnings on social media, advising people to wear masks and remain indoors to reduce exposure.
Chennai also reportedly moved ahead of other Indian cities on global pollution rankings based on live monitoring data. The unusually high readings attracted attention online, with residents expressing concern about the impact of firecracker smoke.
However, official monitoring stations recorded lower readings compared to some live monitoring applications. This difference highlights how pollution levels can vary across locations and monitoring systems. Local firecracker bursts may also create sudden pollution spikes that are not fully reflected in city-wide averages.
The readings have once again raised concerns about the impact of firecracker smoke on air quality and public health during festival celebrations.
