Delhi 'very poor' on Friday, study puts vehicular pollution as top reason

Air pollution became worse after people violated a ban and burnt firecrackers on Diwali on November 4, but the problem was compounded by other sources.

Toxic air shrouded Delhi for another day, making it the second most polluted city on the planet as an environment group’s report said vehicles accounted for 50 per cent of the pollution.

The air quality index (AQI) in Delhi was in the 'very poor' category at 8am, according to the state-run System of Air Quality and Weather Forecasting And Research (SAFAR). Readings below 50 are considered safe and anything above 300 is hazardous or 'severe'.
