A survey conducted by LocalCircles found that around 53 per cent of the Delhi-NCR residents identify stubble burning in neighbouring states as the "primary cause" of rising levels of air pollution. The survey report is based on responses from 20,000 citizens.
Around 10,037 respondents identified stubble burning by farmers in adjoining states as the root cause of bad air quality in the national capital, it said. Delhi's air quality continued to be in the 'severe' category on Thursday with its Air Quality Index (AQI) dipping at 426 at 9.10 am, the Central Pollution Control Board (CPCB) data showed.
The data breakup shows that a much smaller percentage or 13 per cent believe the primary cause is "motor vehicle emissions", while 7 per cent of the respondents blamed it on "garbage burning in the city".
Around 7 per cent respondents held "industrial emissions" responsible and 7 per cent blamed "construction activity", the survey said.
