The Centre’s panel on Delhi-NCR’s air quality has re-implemented stage 3 curbs under the Graded Response Action Plan (GRAP) amid a sharp rise in air pollution levels owing to unfavourable meteorological conditions, according to an official order. Delhi’s air pollution levels showed an increasing trend and the 24-hour average air quality index (AQI) stood at 357 at 4 pm, up from 297 on Wednesday, owing to “calm winds and foggy conditions”.
The Commission for Air Quality Management, responsible for strategising air pollution mitigation in Delhi-NCR, directed authorities in the region to immediately implement curbs prescribed under stage 3 to prevent further worsening of the situation.
What’s closed under GRAP stage 3
During winters, the Delhi-NCR region enforces restrictions under GRAP, which categorises air quality into four stages – Stage I (Poor, AQI 201-300), Stage II (Very Poor, AQI 301-400), Stage III (Severe, AQI 401-450), and Stage IV (Severe Plus, AQI above 450).
Unfavourable meteorological conditions, combined with vehicle emissions, paddy-straw burning, firecrackers, and other local pollution sources, lead to hazardous air quality levels in Delhi-NCR during winters. Doctors say that breathing Delhi’s polluted air is equivalent to smoking approximately 10 cigarettes a day.
