Bengaluru: Rs 427 Cr Spent, Still 'Non-Attainment City' for Air Quality?

• Bengaluru remains a "non-attainment city" under NCAP despite spending Rs 427.43 crore on air quality improvement.
• A "non-attainment city" consistently exceeds National Ambient Air Quality Standards (NAAQS) for pollutants like PM10 and PM2.5.
• Source apportionment study identified major pollution sources: road dust, vehicle emissions, construction, and traffic congestion.
• Measures include mechanical road sweeping, increasing green cover, promoting cleaner transport, and monitoring by committees.
• PM10 levels have fallen by 21.7%, and no "bad AQI" days reported recently, but national standards are yet to be met.
