The air quality index (AQI) in Delhi has taken a turn for the worse. Delhiites have woken up to a thick blanket of smog covering the city. The crop burning in the neighbouring states of Haryana and Punjab are thought to be the cause of the bad AQI.
An AQI between 0 and 50 is considered 'good', 51 and 100 'satisfactory', 101 and 200 'moderate', 201 and 300 'poor', 301 and 400 'very poor', and 401 and 500 'severe'.
The AQI in Anand Vihar, Wazirpur, Vivek Vihar, Mundka, Bawana, Jahangirpuri was 327, 323, 317, 309, 302 and 300 respectively, according to Central Pollution Control Board data.
The air quality in neighbouring Ghaziabad (320), Greater Noida (312) and Noida (310) in Uttar Pradesh and Haryana's Alipur Khalsa (351) and Panipat (339) also turned "very poor".
Faridabad, Greater Noida, Baghpat, Murthal recorded an AQI at 290, 233, 280, 259 and 245 respectively.
The Centre-run System of Air Quality and Weather Forecasting and Research (SAFAR) issued a health advisory, asking people to reduce heavy exertion. "People with heart or kind diseases and children should avoid longer and heavy exertion. Everyone may experience health effects. Significant increase in respiratory problems," it said.
According to PTI, Haryana has reported a slight decrease in the number of stubble burning incidents, Punjab has reported a massive increase of 45 percent in such cases till October 11, according to data of pollution control boards of the two states. Despite a ban on stubble burning in Punjab and Haryana, farmers continue to defy it amid a lack of financial incentives.
Starting from 15 October, stricter measures to fight air pollution will come into force in Delhi and its neighbourhood as part of the Graded Response Action Plan, which was first implemented in Delhi-NCR in 2017. These measures include increasing bus and metro services, hiking parking fees and stopping use of diesel generator sets when the air quality turns "poor".
