Delhi chokes on toxic smog; air quality panel flags ‘recurring negligence’, high dust levels, Pg1

Key Highlights:

• The CAQM reprimanded the DDA for negligence in road maintenance, leading to high dust levels in Delhi.
• Inspections of 136 road stretches revealed visible dust on many, along with MSW and C&D waste.
• Delhi's AQI reached 461 on Sunday, the highest this season, categorized as 'severe plus'.
• Air quality in other North Indian cities like Bahadurgarh, Ghaziabad, and Noida also fell into the 'severe plus' category.

Detailed Insights:

• The CAQM emphasized the need for the DDA to improve operational efficiency and implement timely dust mitigation measures.
• Accumulation of municipal solid waste (MSW), construction and demolition (C&D) waste, and open burning contribute significantly to air pollution.
• The Central Pollution Control Board (CPCB) forecasts a slight improvement to the 'very poor' category, but expects 'very poor' air quality to persist.
• The Air Quality Early Warning System predicts 'very poor' air quality for Delhi from Monday to Wednesday and the subsequent six days.

Key Concepts Involved:

• AQI (Air Quality Index): A measure of air quality based on concentrations of various pollutants.
• CAQM (Commission for Air Quality Management): An authority responsible for air quality management in the NCR and adjoining areas.
• MSW (Municipal Solid Waste): Everyday waste produced by households and commercial establishments in urban areas.
