Environment Minister Gopal Rai on October 24 expressed concerns over the rising pollution in the national capital. He said that the winds are moving in the northwest direction, which could increase the pollution levels in the national capital territory (NCT) due to stubble burning in neighbouring states.
"As per the information given by the meteorological department, the winds are now moving in the northwest direction. The effect of stubble burning from Haryana and Punjab will be more visible in Delhi. We have put all our departments on alert mode given the increase in pollution levels. I am going to write a letter to the Union Environment Minister for the third time, urging him to call a meeting. The research conducted by IIT Kanpur regarding artificial rain should be taken forward to resolve the pollution crisis. All the formalities should be fulfilled. I had also written to transport ministers of neighbouring states to not send diesel vehicles in Delhi till the weather is unfavourable," Gopal Rai said.
Experts say that though, the contribution of stubble burning to air pollution is "well established", it amounts to only 6-8 per cent of the overall air pollution in the national capital in the whole year.
Sagnik Dey, Professor at the Centre for Atmospheric Sciences, IIT Delhi also outlined that the children who are exposed to pollution fires are at increased risk of growth failure.
"During the months of October and November, the contribution of stubble burning in air pollution is around 25-30 per cent. But, if we talk about the whole of the year, the contribution of stubble burning is only 6-8 per cent maximum," he said.
"Curbing the issue of stubble burning is important, particularly in this critical period, but there are many other sources too, and we should work towards that throughout the year. We can't achieve clean air only through stubble burning," he added.
Meanwhile, toxic foam was seen floating in the Yamuna river in Kalindi Kunj as pollution levels in the river continued to remain high.
