Ahmedabad Chokes: PM10 Haze Before Winter
19 Oct
Summary
- Ahmedabad's air quality has worsened significantly before the peak winter season.
- PM10 particulate matter is the primary pollutant, with levels reaching 'severe' in many areas.
- Rampant construction and reduced green cover are cited as major contributors to poor air quality.
The city of Ahmedabad is currently grappling with a severe decline in air quality, marked by a pervasive haze that has settled over its skyline much earlier than anticipated for the winter season. Ambient temperatures remain mild, with minimums around 25-26°C and maximums near 37°C, yet pollution levels are alarmingly high.
Data from the Central Pollution Control Board indicates an average Air Quality Index (AQI) of 252, but real-time readings from multiple locations reveal a more critical situation, with AQI values reaching as high as 364 in some neighborhoods. PM10 particulate matter, linked to road dust and construction, is identified as the primary pollutant, with Gyaspur registering the highest concentration at 189 µg/m³.
Environmental experts point to extensive construction projects and a significant reduction in urban green spaces as key drivers behind the increased PM10 levels. Despite regulations requiring dust prevention measures at construction sites, compliance remains a concern. Physicians also note an increase in dust-related allergies and expect a further spike post-Navratri festivities.
Efforts to mitigate air pollution include covering construction materials, prompt debris removal, and controlling dust during excavation. However, the combination of ongoing construction, atmospheric inversion, and potential increases in traffic-related emissions, especially during morning hours, continues to impact air quality. Only Bavla currently falls within the 'moderate' air quality category.
