Delhi Air Quality Index took a dip on Sunday
Talk of small mercies. Delhiites can now breathe a sigh of relief as the AQI dipped from ‘very poor’ on Saturday to ‘poor’ with a reading of 294 on Sunday.
Delhi, as we know, is one of the most polluted cities in the country. On Friday, it marked and AQI of 352. There was a marginal improvement on Saturday though the AQI was still recorded as ‘very poor’. The primary pollutants in Delhi are PM2.5 and PM10.
This stark improvement comes after the season’s coldest day in the city and due to faster wind speeds across the area. It is believed that due to the faster wind speeds, the pollution slightly dissipated away from the city to the outskirts.
On Sunday, the temperature in the city dipped to the lowest this season - 9 degrees, officially marking the advent of winters this year around. Last year, the coldest day was recorded on 25th November with a temperature of 10.5 degrees. According to the Met department, Delhi will see a further dip in temperature in the coming days and then follow up with a minimal rise in the low temperature. They also said that the city will be graced by increasing levels of fog, smog and mist in the coming days.
The growing fog and mist will help towards cleaning out the atmosphere in the city. As of now, the level of pollutants is hovering three times above what should be the regulated standard. If the trend continues, the results could be life threatening and take a toll on citizens’ lives.
In another move to tackle pollution, IIT Kanpur scientists were given the green flag to go ahead with their plan for inducing artificial rain in the city. As of now, they are waiting for favourable cloud conditions to go ahead with the plan. They stated that all other parts of the plan- the clearances and logistics are favourable and they have received permission to go ahead.
