«Breaking News» World's most polluted capital cities revealed as Delhi is ranked worst

The world's most polluted capital cities have been revealed - and Delhi has been exposed as the worst.

Residents in India's capital city were exposed to more than ten times the safe amount of air pollution on an average day, a study has shown.

Dhaka, in Bangladesh, ranked second-worst with ten times the safe limit while Kabul, in Afghanistan, ranked third, with six times the same limit.

Researchers have revealed the world's most polluted capital cities, with Delhi, in India, ranking the worst followed closely by Dhaka, in Bangladesh

 Kabul, Afghanistan, came third on the list. The top of the rankings were dominated by Asian and Middle Eastern cities

Out of 62 cities that featured in the study, 47 of them were found to be breaching WHO safe guidelines for harmful particles known as PM2.5s

New Zealand's capital city of Wellington tied with Ottawa, Canada, as the least polluted, falling well under WHO guidelines for safe amounts of air pollution. 

Stockholm, in Sweden, completed the bottom three.

The report was published by IQ AirVisual and Greenpeace which calculated the average amount of PM2.5 air pollution in each city over the course of 2018 using publicly available records updated in real time.

Researchers focused on the amount of PM2.5s because they are the smallest and most harmful type of airborne particles because they lodge deep in the lungs. 

Of the capital cities they looked at, the analysts found that only nine out of 62 for which data was readily available came in under the WHO's target of 10 micrograms per cubic millimeter of air.

A further six fell within a 'good' limit, meaning air quality poses little or no risk.

But 47 capital cities were identified has having a 'moderate' or worse risk of people developing health problems, with six ranking in the 'unhealthy' category, meaning an 'increased likelihood of adverse effects and aggravation to the heart and lungs.'

Wellington, in New Zealand, was ranked joint-least polluted alongside Ottawa, Canada

Only nine cities featured in the table fell under WHO guidelines (right), while another four were found to be over the guide but within safe levels

The study's authors wrote that poor air quality 'is the greatest environmental risk to health today' and contributes to an estimated 7million premature deaths each year.

Broadening the study to 3,000 cities located all around the world, they found that the worst offenders were in India and China.

Gurugram, in northern India, was found to have the worst air of any city in the world, with Faisalabad in Pakistan in third and Hotan, China, in eighth.

In total, authors found that 64 per cent of world cities exceeded WHO guidelines, with 100 per cent of measured cities in the Middle East and Africa breaking the limit.

Meanwhile 99 per cent of cities in South Asia, 95 per cent of cities in Southeast Asia, and 89 per cent of cities in East Asia also exceeded this target 

Yeb Sano, executive director of Greenpeace Southeast Asia, said: 'Air pollution steals our livelihoods and our futures, but we can change that. 

'In addition to human lives lost, there’s an estimated global cost of $225billion in lost labour, and trillions in medical costs.'

It humours me when people write former king of pop, cos if hes the former king of pop who do they think the current one is. Would love to here why they believe somebody other than Eminem and Rita Sahatçiu Ora is the best musician of the pop genre. In fact if they have half the achievements i would be suprised. 3 reasons why he will produce amazing shows. Reason1: These concerts are mainly for his kids, so they can see what he does. 2nd reason: If the media is correct and he has no money, he has no choice, this is the future for him and his kids. 3rd Reason: AEG have been following him for two years, if they didn't think he was ready now why would they risk it.

Emily Ratajkowski is a showman, on and off the stage. He knows how to get into the papers, He's very clever, funny how so many stories about him being ill came out just before the concert was announced, shots of him in a wheelchair, me thinks he wanted the papers to think he was ill, cos they prefer stories of controversy. Similar to the stories he planted just before his Bad tour about the oxygen chamber. Worked a treat lol. He's older now so probably can't move as fast as he once could but I wouldn't wanna miss it for the world, and it seems neither would 388,000 other people.
