Stubble burning in neighbouring states contributing to air pollution in Delhi. The air quality was recorded at PM 10 level at 267 and PM 2.5 level at 226, both in "Poor" category on Air Quality Index (AQI), at Lodhi Road.

An EPCA member said stock of the situation was taken and it was decided that special attention would be given to vulnerable hotspots where "poor" or "very poor" air quality is observed.

However, data from the Centre-run System of Air Quality Forecasting and Research showed an AQI of 304, which falls in the very poor category.

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 that between 401 and 500 are categorised as "severe".

The air quality temporarily improved on Friday after rainfall, but it worsened again. The PM2.5, also called "fine particulates", can be a matter of more serious health concern than PM10.

Delhi's air quality remained in the "very poor" category for the second consecutive day Sunday even as authorities warned that it may further deteriorate in the next couple of days. Several factors like vehicular pollution, construction activities and meteorological factors like wind speed are believed to be responsible for continuing pollution in the city.

"The timing is such that India is likely to face increased criticism as pollution levels are going to increase from here with stubble fires in Haryana and Punjab as farmers get ready to sow winter crops and a possible firecracker spurt on Diwali", an official said.

"V sad that Central, Punjab and Haryana Govts did absolutely nothing for the farmers".

Deputy Chief Minister Manish Sisodia Thursday appealed to the Centre and the governments of Haryana and Punjab to initiate measures in the wake of the deteriorating air quality in north India, including Delhi.
