The second phase of Odd-Even rule has miserably failed in the national capital as the air pollution levels in Delhi rose by over 23 percent from April 15 to April 29. The analysis of air pollution was done by estimating the levels of PM (particulate matter) 2.5 and PM 10.
Arvind Kejriwal’s second implementation of the 15-day experiment was meant to curb the deteriorating air pollution but eventually it ended up worsening the situation. According to reports, particulate matter rose thrice the permissible limits.
According to data released by the Union Ministry of Earth Science’s SAFAR index, the level of PM 2.5 was measured above 184.3 micrograms per cubic metre on the last day of the experiment while the level of PM 10 was hovering around 362.2 micrograms per cubic metre. It is to be noticed that permissible limits of PM 2.5 and PM 10 are 60 and 100 micrograms per cubic metre respectively but they are present in three times more than the standard limit.
Dr. Gufran Beig, the programme director of SAFAR said that air quality dipped in last three days but it showed some improvements on the last day and such slight fluctuations are normal in the city like Delhi.
At the start of the second phase of Odd-Even rule on April 15, was 120 micrograms per cubic metre which is twice the standard limit. The 15-day experiment increased the PM 2.5 levels to thrice the permissible limit.
While explaining a government official said that it is hard to check the pollution levels as it varies vastly in different parts of the city. “This would have been possible in a laboratory. But, in a city as vast as Delhi it is nearly impossible to identify the impact. There would definitely be some impact as we are reducing the number of cars, but it is difficult to calculate,” said the official.
