New Delhi: Delhi is observing its second car free day on Sunday, November 22. It is being organized between Dwarka sector 3-13 and 7-9 from 8 AM to 4 PM.

On October 22nd, Delhi had its first car-free day and it had successful results as there was 60 per cent decline in Delhi’s pollution.

The other positive was less traffic. People waste so much of time in traffic which is the extra burden on a working person, especially as the traveling time is not counted anywhere.

Chief Minister Arvind Kejriwal urged people to be a part of the initiative on Twitter. He also declared that next month car free day will be observed in east Delhi areas and on 22nd January, whole Delhi will have car free day.

Today will also mark the start of ‘Swachh Delhi’ campaign. Its mobile app had received 1500 complaints by the morning.

The app was launched to receive complaints. Delhi will have intense cleanliness campaign from 22nd to 30th November. All a user has to do is upload the picture of garbage wherever he sees and the government will take action.

The pollution in Delhi has been a huge problem and with it, comes the rise of many diseases. The city has been reported as one of the most polluted in the world.

The traffic also is an issue, as traveling in Delhi takes up so much of time even though millions are commuting through the metro.

The number of cars parked in any residential area tells the story. Half of the area of the roads is blocked by the parked cars.

With population increasing all the time, it is natural that personal vehicles would increase. However, there are people who possess way more automobiles than they need. It is also the mark of a high class citizen, and the desire to be at higher social status is one reason for rising number of vehicles.

There has been a push to encourage people for carpooling. While, the concerns regarding environment are the priority, but the saved time is the big bonus.

Climate change has been a big topic in the world. Every little effort makes an important difference and the initiative of the car-free day and Swachh Delhi are good steps from Delhi government. All that is required now is that support from the citizen.

Another requirement is a follow-up from the government. It should not happen that for these 10 days the government shows immense pro-activeness and results are seen, but soon after that, things start running in their old ways again. If a plan is initiated then it should be completely taken care of.

Air Pollutants Can Be Stopped If They Are Frozen : Scientists

The air-quality across the NCR was very poor

Freezing pollutants can prevent deadly outdoor air pollution — thought to cause more than three million premature deaths worldwide every year — from seeping indoors by 99 per cent, scientists have discovered.

The research, by a team of scientists from the Nottingham Trent University in the UK and the Chinese Academy of Sciences, involved studying the effectiveness of cryogenics for indoor air purification, by removing the gaseous pollutants and tiny particulates caused by haze.

The team found that as they circulated haze-polluted air through a cryogenic condenser, the finer particles stuck together in the condenser tube before dropping out by gravity, and emerging as clean air.

Their method was able to remove 99 per cent of particulates and 98 per cent of nitrogen oxide pollutants.

“Hazardous outdoor air pollution has severely affected indoor air quality, threatening the health of billions of people,” said Professor Robert Mortimer, Dean of the School of Animal, Rural and Environmental Sciences at Nottingham.

“Outdoor air pollution in cities is a global problem. While there are some existing technologies to purify indoor air, they can be inefficient, expensive or produce harmful by-products.

“When outdoor air quality is poor, people tend to spend even more time indoors – but outdoor pollution also leads to indoor pollution and people are still impacted.”

The experiments, reported in the journal Science of the Total Environment, showed that by simply circulating polluted air through a small freezing chamber we can remove most of the fine particles and gas pollutants.

“Our study makes it possible to add an ‘air cleaner’ option to household appliances in areas which might experience extremely poor air conditions. By controlling indoor air pollution and improving air quality in this way, this work could be greatly beneficial for public health,” added Gang Pan, Professor at the varsity.

It is hoped that the work could pave the way for simple modification of air conditioning and humidifier units so that they can also clean polluted indoor air, the team said.

Delhi and the National Capital Region (NCR) on Sunday witnessed “very poor” air quality with the minimum temperature recorded at 12.4 degrees Celsius, two notches below the season’s average.

The air-quality across the NCR was very poor, according to System of Air Quality and Weather Forecasting And Research.

The humidity at 8.30 a.m. was 87 per cent. The maximum temperature was likely to hover around 28 degrees Celsius. (IANS)
