The Indian capital New Delhi looks at ways to combat its annual pollution crisis.
On Wednesday, authorities conducted a trial run of an “anti-smog gun” or a machine that sprays atomized water into the air in one of its most polluted areas as the city expects to bring down pollution levels.
The anti-smog gun, shaped like a hair dryer and mounted on a flatbed truck, was tested in Anand Vihar area of New Delhi.
“The trial run is being held at the Anand Vihar bus terminal. After our meetings, we figured that if we can put water or mist from above or if it rains, then it will help in bringing down particulate matter, pm 2.5, pm 10 and other pollutants. So, keeping this in mind, we conducted the trial run. We have noted the pollution levels before and after using the anti-smog gun, and then we will check how much pollution levels have gone down after using it,” said Delhi environment Minister Imran Hussain.
The “anti-smog gun” will be rolled out in the streets of New Delhi if it turned out to be successful, the official said.
According to A U.S. Embassy measure, the level of pm 2.5 stood at 408 at 2 pm on Wednesday eight times the upper limit of “good” quality air at 50.
This is an improvement over last week when the pollution levels climbed to 12 times above the recommended limit.

Once home to rice farmers and their luscious green paddy fields, this Indonesian village is now a dump for truckloads of rubbish.
As Indonesia looks to tackle the country’s growing mountain of trash, the residents of East Java’s 200-hectare Bangun village have found a way to reel in profit from the problem — by opening their gates to garbage trucks and choosing to turn their fertile fields into rubbish sorting plots.
The health and environmental repercussions for Bangun village might be huge, said non-government organization, Ecological Observation and Wetlands Conservation (ECOTON), which has been observing the issue in the area for the last five years.
Now, more than 60 percent of the village residents have opted to enter the rubbish sorting business, and for the time being, that looks unlikely to drop.
“If I’m farming, I need to wait three months to get results, but if I’m sorting rubbish, we can make money in a day, two days or even a week,” said one farmer, Siti Maimanah.
On average, a worker in Bangun can earn between $7-14 per week picking through the sea of paper and plastic, and that can rise to $35 if the piles are particularly high – a tempting proposition when the farming alternative would leave them waiting with nothing for weeks on weeks, said Maimanah.
Ecoton said it has obtained evidence that the garbage in the area is imported from at least 54 countries around the world, including Europe, the United States, Australia, and Asia, under the pretense it is ‘paper waste’. Reuters found plastic packaging amongst the piles, including from Canada and the United States.
That’s adding on top of the huge amount of garbage the world’s fourth-most populous country with 260 million people generates on its own.
Earlier this year, the city of Surabaya sent back more than 200 tonnes of trash to Australia and U.S. as part of efforts to push back ‘foreign trash’ amid a spike in imports from Western countries after China banned imports.
“Our country has been labeled a dirty country and now America is adding their rubbish on top. Sending this garbage is clearly a violation of the law,” said Ecoton’s protest coordinator, Prigi Arisandi, during a recent protest in front of the U.S. consulate in Indonesia’s second-biggest city, Surabaya.
The archipelago of more than 17,000 islands has been struggling to cope with the waste, with much of it going into landfill and often eventually seeping out to pollute rivers and oceans. According to a 2015 study published in the Science journal, Indonesia was the world’s second-biggest contributor of plastic pollutants in the oceans.
The mountain of trash in Bangun village is also not going to vanish overnight despite the government’s efforts and plan to set up waste-to-energy plants across the country.
And for now, Indonesians like Maimanah say their day-to-day survival is far more important than the environment. (REUTERS)
German and Swiss scientists have published a study suggesting that microplastic is being blown vast distances through the air and dumped when it snows, underscoring the threat the growing form of pollution poses to marine life in even the remotest waters on the planet.
The team, from the Alfred Wegener Institute (AWI), analyzed snow samples in Germany, the Swiss Alps and on the Norwegian Arctic archipelago of Svalbard to confirm that the snow in all places contained high concentrations of plastic fragments, known as microplastic.
“It’s readily apparent that the majority of the microplastic in the snow comes from the air,” lead researcher Melanie Bergmann said in a press release.
The highest concentration in samples was collected in a rural area in Germany’s southern province of Bavaria, totaling to 154,000 particles per liter. The snow in the Arctic contained up to 14,400 particles per liter in comparison.
Researchers found particles of nitrile rubber, acrylates and paints containing plastics in their snow samples.
The study, published on Wednesday (August 14), is reinforced by research conducted by a U.S.-led team of scientists in the Northwest Passage. The team found the material trapped in ice taken from Lancaster Sound, an isolated stretch of water in the Canadian Arctic, which they had assumed might be relatively sheltered from drifting plastic pollution.
Eighteen ice cores of up to 2 meters (6.5 feet) long were drawn from four locations, containing visible plastic beads and filaments of various shapes and sizes.
The plastic fragments serve to highlight how the waste problem has reached epidemic proportions.
The United Nations estimates that 100 million tonnes of plastic have been dumped in the oceans to date. (REUTERS)
