Smoke from neighbouring states caused pollution in Delhi
The recent pollution cloud in Delhi was due to smoke caused by burning of the biomass residue in the paddy fields of rural Punjab and Haryana, parliament was told Monday.
Replying to a question in the Rajya Sabha on smog in Delhi early this month, Science and Technology Minister S. Jaipal Reddy said the smoke got directed towards Delhi region due to favourable northerly winds.
"The period being the harvesting season of Kharif crops and the open burning of the biomass residue in the paddy field caused the trouble," he said.
"Incrementally, diesel operated urban transport also adds to the air pollution that reduces the visibility further. Government is already undertaking possible steps for discouraging diesel run public transport and encouraging utilization of CNG," he said.
Reddy said the smog is known to cause respiratory related asthmatic troubles among children and elderly.
