Delhi's Air Quality Hits 6-Year October Low
5 Oct
Summary
- Delhi's air quality worsened for five consecutive days, reaching a six-year October low.
- PM10 particles are the dominant pollutant, largely from road dust and construction.
- Experts urge year-round emission reductions for long-term air quality improvement.
The national capital's air quality has declined for five consecutive days, registering the most polluted October start since 2020. As of Sunday, the Air Quality Index (AQI) averaged 187, placing it in the 'moderate' category. This marks the worst AQI recorded in 82 days.
PM10, primarily coarse dust particles from sources like road dust and construction, has been identified as the dominant pollutant. While recent rainfall had temporarily improved air quality, a lack of precipitation and localized emissions have led to this recent surge in pollution.
Experts like Jinitha Varghese highlight that seasonal factors like stubble burning and dust contribute to immediate spikes, but long-term relief necessitates targeting structural pollution sources. This includes comprehensive emission load reductions from power plants, industries, waste management, and transportation.
Several monitoring stations reported "poor" air quality, with Mundka recording the highest AQI at 273. Looking ahead, forecasts suggest a dip in minimum temperatures over the week, with potential for very light rain on Tuesday. Meanwhile, the Commission for Air Quality Management (CAQM) has identified 17 violations related to road dust and construction waste, directing corrective measures.
