IQAir, a global air quality monitoring company The 2023 Climate Report finds the 100 cities with the worst air. There are 99 cities in Asia and 83 cities are in “India”. The city with the worst air in Thailand is Phan District, Chiang Rai Province, ranked 115th.
- IQAir’s 2023 Climate Report finds India’s Begusarai is the world’s most polluted city. With PM2.5 concentrations 23 times higher than WHO criteria, Bangladesh has become the country with the worst air quality in the world. 16 times more than the WHO criteria.
- “Thailand” has the 36th worst air quality in the world and the 5th in Southeast Asia, with Phan District in Chiang Rai Province and Pai District of Mae Hong Son Province ranked among the top 5 areas with worst air quality. PM2.5 toxic dust is the worst in Southeast Asia.
- Of the 134 countries and regions surveyed in the report, only 7 cities have clean air. PM 2.5 levels are within the WHO guidelines, which is that average annual PM 2.5 levels should not exceed 5 micrograms per cubic meter.

IQAir tracking companyAir quality around the world Annual weather report 2023 Found the 100 cities with the worst air There are already 99 cities in Asia and 83 cities are in “India“with”PM2.5” Exceeds the standards of the World Health Organization or WHO by more than 10 times.The city with the worst airIn Thailand, Phan District, Chiang Rai Province is ranked 115th.
However,climate crisisIt plays an important role in causing poor air quality. It is harmful to the health of billions of people around the world.
“South Asia” has the most toxic air in the world.
This study collected data onlyand small dust particlesOr PM2.5, which is the smallest pollutant, measuring only 2.5 microns, or 1/30th of the diameter of a single strand of hair. But it is the most dangerous. By collecting data on 7,812 cities, covering 134 countries, regions and territories, it was found that only 9% of cities have air quality that meets WHO standards, which states that annual average PM2.5 levels should not exceed 5 micrograms per cubic meter.
Begusarai, a city of about 500,000 people, is located in the northern Indian state of Bihar. It was crowned the world’s most polluted city in 2023, with an annual average PM2.5 concentration of 118.9, which is 23 times higher than WHO criteria.
Rankings 2-4 are still cities in India, including 2nd place Guwahati in the state of Assam, 3rd place Delhi and 4th place Mullanpur in the state of Punjab.
The report states that India’s population of 1.3 billion, or 96% of the country, lives in an environment with PM2.5 value 7 times higher than specified
The top 10 countries with the highest PM2.5 values in 2023 will be found:
1. “Bangladesh” became Countries with the worst air quality in the world With PM2.5 values as high as 79.9, which is 16 times higher than the WHO criteria.
It can be seen that all countries are in the regions of South Asia, Central Asia and Africa, but the most worrying is “South Asia” because there are 29 cities in India, Pakistan or Bangladesh among the top 30 cities with the most air pollution.
“We have seen that air pollution affects every part of our lives. And extreme weather conditions can kill people in three to six years, creating suffering for citizens,” said Frank Hammes, CEO of IQAir Global.
Small dust particles come from many sources, including burning fossil fuels Such as coal, oil and gas, dust storms, garbage burning and forest fires when PM2.5 is inhaled into the body. Tiny dust This can enter the lung tissue. and can enter the bloodstream There are many studies indicating that PM2.5 causes asthma. Heart and lung disease, cancer and other respiratory diseases, as well as intellectual disability in children
air pollution It kills an estimated 7 million people worldwide each year, more than AIDS and malaria combined. Those most affected are developing countries andpoor countrythat rely on dirty fuels for heating Cook and light the family. This will cause air pollution within the residence as well.
Hammes said pollution levels would not improve without changes to energy and agricultural infrastructure.

IQAir found that air quality in Southeast Asia in 2023 was worse than in 2022, with the amount of toxic PM2.5 dust increasing by more than 20 percent, and in five areas with poor air quality, there wereAmount of toxic dust PM2.5 More than 50 micrograms per cubic meter. In 2022, no area has an annual average higher than this.
“Thailand” has the 36th worst air quality in the world and the 5th in Southeast Asia. There is an annual average amount of PM2.5 toxic dust of 23.3 micrograms per cubic meter. This is 4.7 times higher than the WHO air quality recommendation, which is a 28% increase compared to 2022.
Meanwhile, Phan District in Chiang Rai Province and Pai District of Mae Hong Son Province were ranked among the top 5 areas with the worst PM2.5 toxic dust in Southeast Asia, at 18.1 micrograms per cubic meter. The period between February and April 2023 is the period with the worst air quality. In Chiang Mai Province, the monthly average of PM2.5 toxic dust increased from 53.4 to 106.4 micrograms per cubic meter. This is an increase of more than 150 percent compared to the monthly average for the same period in 2022.
As for Bangkok, it is theCities with poor air qualityIt is ranked as the 37th most air polluted city in the world. There is an annual average amount of PM2.5 toxic dust of 21.7 micrograms per cubic meter.
Data from Greenpeace reports Thailand says the expansion of maize is a key driver for expanding cross-border investment and farmland in the Mekong sub-region. In the end, it causedToxic dust crosses the borderReturning to Thailand, the government should urgently require the Clean Air Act to provide a transparent traceability system throughout the supply chain and enforce laws that can criminalize the meat industry linked to transboundary toxic dust and deforestation. Because this is an urgent crisis that the government must give importance to the health of the people. more than the profits of industrial companies.”
There are only 7 cities with clean air.
Of the 134 countries and regions surveyed in the report, only seven cities have clean air with PM 2.5 levels within WHO limits.
1. San Juan in Puerto Rico (2.7) has the best air in the world.
The world’s air is generally much cleaner than it has been in the past century. But there are still places where pollution levels are extremely dangerous. Developed countries are also affected by this, such as North America being heavily affected byforest fireinCanadaDuring May-October last year The report found that Alberta’s monthly averages for air pollution in May were the same. Canada was nine times higher than in 2022, making 2023 the first time Canada had higher pollution levels than the United States.
Meanwhile forest fire It also affects cities in the United States. Minneapolis and Detroit also had average annual pollution increases of 30% to 50%, respectively. But the most polluted city in the US in 2023 was Columbus, Ohio, which topped the list. The position continued for the second year in a row.
Hammes said:cross-border pollution” isAnother big problem in the world Because toxic fumes can spread from one country to other countries and may result in worse air quality in the destination country.
For example, cities in the United States were affected by forest fires in Canada. while the northern part of Thailand is affected by the birth ofheat pointIn Myanmar, South Korea has to deal with PM2.5 pollution from winds blowing smoke from coal-fired power plants in northern China into the country. Meanwhile Many countries in the Caribbean have good weather. Because the wind blows away air pollution.
Although much of the world has increased air pollution, But there are still some areas of the world with better air quality. For example, China, where even last year industrial and economic activity began to recover after the COVID-19 outbreak. But it can still handle PM2.5 reasonably well.Dust levelBut Chile, which had major forest fires in February 2022, reported a 15% drop in PM2.5 pollution from 2022, as well as South Africa’s annual average PM2.5 concentration also falling by a 6.5% increase. Similar to Chile
from report data World air quality in 2023 It shows that every country needs to focus onSolving the problem of toxic dustat the root causes of PM 2.5 seriously, by setting policies and budgets and elevating it to an important global problem that requires urgent action effective Taking into account the interests of the people over those of industrial capital. Because access to clean air is a basic right of all people on this planet.
