The toxic smog hovering over Delhi lifted on Tuesday morning with bright sunshine and wind speeds aiding dispersion of pollutants, and pollution levels coming down considerably from “severe” to “very poor” category after almost a week.

This will bring a huge relief to the population grappling with toxic air and also a brief respite to policymakers struggling with ways to control this emergency air pollution.

According to Safar India, the overall air quality index in Delhi has hit 381, much below the 600 plus levels in the last few days.

Even the main pollutants level has dropped. PM 10 is at 307 in the poor category and PM 2.5 at 221 in the very poor category.

According to a Safar India forecast, significant improvement in hourly value started on Monday morning as sun rays penetrated, however, the 24 hour running average will come down only slowly.

High surface and boundary layer wind are expected for Wednesday as well which will also improve air quality.

The Supreme Court on Friday said in spite of Odd-Even vehicle rationing scheme, pollution has reached a severe level, and again called the Chief Secretaries of Delhi, Punjab, Harayana and Uttar Pradesh, to report on measures taken to curb air pollution particularly related to stubble burning.

A bench headed by Justice Arun Mishra said, “Do not give exemption to two-wheelers, and it will work.”

During the hearing, the judges scrutinized the Odd-Even scheme of the Delhi government in respect of air quality index data gathered in the past two years. The judges queried the Delhi government counsel, senior advocate Mukul Rohtagi, what purpose the scheme served by keeping out cars which contribute mere three per cent of the total pollution.

The court observed that Delhi’s local pollution is a major problem, if stubble burning which contributes 40 per cent is kept out.

“According to the authorities, stubble burning has reduced to somewhere near five per cent now…we are concerned about Delhi’s local air pollution. What is the government doing?”

The court observed the data presented by the authorities suggest the Odd-Eeven scheme had hardly any effect on improving air quality. “Question is what are you gaining by this scheme?” observed the court.

Further commenting on the social aspect of the Odd-Even scheme, the court said “Odd-Even will only affect the lower middle class but not the affluent ones since they have multiple cars… Odd-Even isn’t a solution, but public transport could be. But nothing has been done about that”, said the court.

The hearing on the matter will continue on November 25. (IANS)
