Mumbai's Air Quality to Deteriorate Sharply after Diwali

Strategic Insights -

Mumbai is bracing for a significant pollution spike due to the approaching Diwali celebrations, with environmental experts warning of a sharp deterioration in air quality. According to Dr. Tuhin Banerji of the Bombay Environment Action Group, Mumbai's Air Quality Index (AQI) is expected to cross 350 on several days, reaching the "very poor" category, due to weakened wind circulation, dry weather conditions, and firecracker emissions. This comes after the AQI breached the 100 mark on October 10, moving from the "good" to the "moderate" category for the first time since the end of the monsoon.

Key Takeaways:

  • Mumbai's air quality is expected to deteriorate sharply after Diwali due to firecracker emissions, dust, and stagnant weather conditions.
  • Dr. Tuhin Banerji of the Bombay Environment Action Group predicts that Mumbai's AQI will cross 350 on several days, reaching the "very poor" category.
  • Weakened wind circulation and dry weather conditions have contributed to the deterioration in air quality.
  • The drop in air quality has been attributed to a combination of disrupted wind patterns, ongoing infrastructure projects, and increased vehicular and industrial emissions.
  • Exposure to poor AQI for six to eight hours can affect human health, particularly the respiratory tract.
  • Pollution control board officials have implemented measures to close polluting installations with smoke chimneys and those generating dust.
  • Experts warn that the situation may deteriorate further as Diwali approaches, trapping pollutants closer to the ground.

Statistics:

  • Mumbai's Air Quality Index (AQI) is expected to cross 350 on several days, reaching the "very poor" category.
  • AQI breached the 100 mark on October 10, moving from the "good" to the "moderate" category for the first time since the end of the monsoon.
  • Six to eight hours of exposure to poor AQI suffices to affect human health, particularly the respiratory tract.
  • 16 hours of exposure to poor AQI is necessary to adversely affect the human body.
