The list of the world’s top 20 most polluted cities is out. All but one are in Asia

A new study suggests that everything was in Asia, except one of the 20 most polluted cities in the world last year.

The majority of these cities are in India, the most populous country in the world, where economic growth is rapidly fired by coal and where hundreds of millions of people live in traffic and live in dense mega.

Another four neighboring countries are in Pakistan, one of which is in China and Kazakhstan respectively.

The only city outside Asia on the list is N Djmina, the capital of Chad, Central Africa’s Chad – which was named the country with the worst air pollution.

Meanwhile, the worst pollution cities in North America were in California.

A Swiss company, which tracks global air standards, is seen on a report, especially good particle, or PM2.5, which is one of a small but dangerous pollution.

PM2.5 comes from sources like fuel, dust storms and wildfire combustion. It is so small – 1/20th of human hair width – that it can travel in your lungs or bloodstream by your normal defense.

Particles cause irritation and inflammation and are linked to respiratory problems and kidney disease. Exhibition can cause cancer, stroke or heart attack and is associated with high risk of depression and anxiety.

The World Health Organization (WHO) says the average annual level of PM2.5 should not exceed 5 micrograms per cubic meter.

The Bornees, an industrial town in northeastern India, recorded a PM2.5 concentration of 128.2 last year – which is more than 25 times the WHO standard.

“It seems very sad and helpless that the bornees are at the top of the list,” “the 26 -year -old, who lives in a city of about 70 70,000, told CNN.

He accused the city’s factories and at a height of the construction industry and trees as to contribute to the poisonous air.

He said, “Pollution is especially bad at this time, Maritime is not very good, everywhere is dust, my eyes are burning.”

“I don’t leave home without a mask.”

Twelve other cities in the top 20 are in India.

Its capital is prominent in New Delhi as the world’s most polluted capital for the sixth consecutive year, with a 91.8 PM2.5 concentration. The report also includes six satellite cities – Faridabad, Loni, Delhi, Grogram, Noida and Greater Noida.

Just last November, a smoke -packed blanket settled over Delhi, disrupts flights, prevents the buildings from seeing and forcing the city’s chief minister to declare “medical emergency”.

According to the report, in total, India – with 1.4 billion people, is ranked third to fifth from last year.

But the report states that air pollution is “a special burden of health … According to the estimation, reduce life expectancy for 5.2 years.”

According to the report, India’s neighbors were the second and third most polluted countries globally in terms of home-PM 2.5 molecules of 400 million people together.

China – who used to dominate Global rankings The report states that about the worst air in the world – a small improvement is mentioned.

The report states that its national annual average pm2.5 concentration has dropped from 32.5 micrograms to 31 meters, which has improved air quality in Magesti such as Beijing, Shanghai, Chengdu, Guangzhou and Shenzhen.

China is the world’s largest carbon dioxide amater, but in recent years, especially in cities that have launched a campaign against air pollution, in cities that have its economic growth, and extended widespread expansion of solar and wind power.

But last month, two clean energy groups raised the alarm about them, which they said, with China’s power industry, last year had plans to produce about 100 GW coal plant capacity, the highest in the almost a decade.

The IQ Air report states that in the world’s 20 most polluted cities, the PM 2.5 guide letters last year are more than 10 times.

“Air pollution is a major threat to both human health and environmental stability, yet the widespread population is unaware of their exposure levels,” said Frank Hams, the global CEO of Akir.

Iran and Afghanistan did not highlight this year’s report due to lack of data availability.

The report states that monitoring air quality in Southeast Asia is also a problem, in which almost all countries “make significant differences in government -led measures.”

In 2024, 173 out of 392 cities in the region had a shortage of government surveillance stations, while Cambodia had no one.

Following the US announcement earlier this month, these issues are likely to stop sharing the air quality data collected from its embassies and consulates around the world due to “funding barriers”.

“The quality data of the air saves life,” said Hams.

“It creates a lot of awareness, is aware of policy decisions, guidance of healthcare intervention, and gives communities the authority to take action to reduce air pollution and protect future generations.”

The report states that only 17 % of the 8,954 cities analyzed globally by IQID, recorded the air quality, which meets the pollution guidelines.

The report said that the worst air pollution cities in North America were Ontario, Bloomington and Huntington Park. They were all in California.

Overall, the United States saw a significant decline in PM 2.5 level last year, with an annual average falling from 2023 to 22 percent.

North America has long been proud of air quality surveillance systems, which have contributed 56 % of the total number of air quality monitoring stations on the ground-based IQ Air report-helping the scientists help policy makers to make decisions about air quality and make decisions about public health.

Only 12 countries and regions were recorded under the WHO leader’s posts in 12 countries and regions, most of which were in Latin America and the Caribbean or Oceania.

The report calls for governments to dedicate funds to renewable energy projects and “strengthen emissions limits for vehicles and industrial activities.”

The advice Soman wants authorities in the Branites to take Take to prevent their city from falling on the top of the most polluted list next year.

He told CNN, “People nearby have created breathing problems in many years.”

“This is my birth. I am a local. I do not want to leave this area. We want governments to work more, come together and work for us.
