As air quality in the national capital continues to worsen, the Delhi government on Tuesday released latest Nasa images showing large-scale stubble burning in its adjoining states.
The images showed large-scale burning of crop residue in Punjab and Haryana.
The Delhi government has also released wind pattern forecast and variation in concentration of particulate matter charts along with the latest NASA images.
Delhi's pollution level has already touched 301 (air quality index or AQI, as on October 14), which is considered unhealthy and can cause acute respiratory infection, especially among children less than five years.
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 Centre-run System of Air Quality and Weather Forecasting And Research (SAFAR) issued a health advisory, asking people to reduce heavy exertion.
According to the advisory, "people with heart or kind diseases and children should avoid longer and heavy exertion. Everyone may experience health effects, a significant increase in respiratory problems."
Generator sets banned
As air quality in several places in the city and adjoining areas slipped to "very poor" level, Delhi on Tuesday banned generator sets, barring those being used in essential and emergency services.
The ban on generators is a part of the Graded Response Action Plan (GRAP), a set of stricter anti-pollution measures to be taken according to the severity of pollution that came into force on Tuesday.
This is the first time that the ban on gen-sets has been extended to NCR cities of Gurgaon, Ghaziabad, Noida, Greater Noida, Faridabad, Sonepat, Panipat and Bahadurgarh.
