Twelve pollution monitoring stations located in various parts of Delhi recorded severe air quality while 20 stations recorded very poor air quality, according to data by the Central Pollution Control Board. A CPCB-led task force has recommended to Supreme Court appointed Environment Pollution Control Authority implementation of stringent measures from November 1 to 10, predicting further deterioration in the air quality ahead of Diwali.
Some of these recommendations include shut down of coal and biomass factories, intensification of inspection by the transport department to check polluting vehicles and control traffic congestion in Delhi NCR during November 1-10. The task force also issued an advisory to the public, asking them to avoid outdoor strenuous activities and minimise the use of private vehicles.
