Pune's Air Quality Plummets Ahead of Diwali

Strategic Insights -

Pune's air quality is deteriorating rapidly due to the onset of Diwali celebrations and low temperatures, with Katraj recording an air quality index of 197, teetering on the edge of the "poor" category. The Indian Institute of Tropical Meteorology (IITM) scientist attributed the poor air quality to a combination of low temperatures and firecracker emissions, which create perfect conditions for pollution accumulation. The city's low wind speed of 1.9 km/hr is further exacerbating the situation, making it difficult for pollutants to disperse.

Key Takeaways:

  • The air quality index in Katraj reached 197 on Friday morning, just below the "poor" category threshold of 200.
  • The minimum temperature in Pune plummeted to 19.3°C, the lowest so far this October, contributing to the poor air quality.

  • Pune's low wind speed of 1.9 km/hr is making it difficult for pollutants to disperse, exacerbating the situation.
  • SAFAR data showed that both PM10 and PM2.5 levels in Pune have shown an upward trend since October 24, with PM10 levels peaking at nearly 95 µg/m³ and PM2.5 levels increasing to about 50 µg/m³.
  • The Maharashtra Pollution Control Board (MPCB) has started monitoring noise levels and air quality at various locations in the city ahead of Diwali, including 11 locations for noise monitoring and dedicated locations for air quality monitoring.
  • The MPCB will monitor air quality parameters such as PM10, PM2.5, SO2, and NO2 as per the Central Pollution Control Board's guidelines, along with decibel levels in terms of noise pollution.

Statistics:

  • The air quality index in Katraj reached 197 on Friday morning.
