Every year, the World Health Organization releases a report on the most polluted cities globally. The report looks at air pollution levels and how they impact public health. This year’s report was released in February 2020, and it shows that the most polluted city in the world is Ahvaz, Iran. The city has an annual mean concentration of small particulate matter of 217 micrograms per cubic meter.
This is more than twice the level considered safe by the World Health Organization. Other cities in Iran also appear high up on the list, with four other Iranian towns making it into the top 20.
The second most polluted city in the world in Delhi, India. Delhi has an annual mean concentration of 175 micrograms per cubic meter of small particulate matter. This is more than three times the level considered safe by the World Health Organization.
According to the CDC, high air pollution levels can cause an increased risk of heart attack, wheezing, coughing, breathing problems, and irritation of the eyes, nose, and throat. Air pollution can also cause worsening of existing heart problems, asthma, and other lung complications.

10. Noida, India
Noida, India, is one of the most polluted cities in the world. The main reason for this is the high number of factories and vehicles in the city. As a result, the air quality is so poor that it often exceeds the safe limit for breathing set by the World Health Organization (WHO). In addition to causing respiratory problems, pollution also contributes to heart disease and other health problems.
The government has taken some steps to reduce air pollution, but they have been largely unsuccessful. One reason for this is that many of the factories are owned by wealthy businessmen who are not interested in reducing emissions.
There are few restrictions on vehicle emissions, and most of the cars in Noida are very old and pollute a lot. Moreover, the situation is likely to worsen as more people move to Noida in search of jobs.

9. Beirut, Lebanon
Beirut, Lebanon, is one of the most polluted cities in the world. The World Health Organization (WHO) has named it one of the most polluted cities in 2020. The high levels of pollution are caused by car exhaust, factory emissions, and dust from construction sites.
Pollution causes several health problems, including asthma, heart disease, and cancer. The air quality in Beirut is so bad that it is equivalent to smoking two packs of cigarettes a day.
The government has taken steps to address the problem, but the high levels of pollution are unlikely to be eliminated soon. Beirut is a city growing rapidly, and with that growth comes more pollution.

8. Accra, Ghana
According to the UNEP, Accra is one of the most polluted cities in the world. In 2020, it will rank as the 9th most polluted city. This is mainly due to the high levels of particulate matter in the air. The main sources of pollution in Accra are vehicle emissions, waste burning, and industry.
The effects of air pollution are devastating for public health. Air pollution can cause respiratory problems, heart disease, and premature death. It also contributes to global warming, which causes extreme weather events such as floods and droughts.
The government of Ghana is aware of the problem and has been working to reduce air pollution. However, much more needs to be done to protect people’s health in Accra. Citizens must also take action by using public transportation instead of cars, avoiding burning waste, and advocating for cleaner air.

7.Dhaka, Bangladesh
Dhaka, Bangladesh, is one of the most polluted cities globally. The air quality is so poor that it is estimated that about 4,000 people die each year from breathing in the toxic air. Dhaka also ranks as one of the most congested cities in the world. The combination of pollution and congestion makes it a complex city to live in for many of its residents.

6.Ulaanbaatar, Mongolia
Ulaanbaatar, the capital of Mongolia, has been identified as the most polluted city in the world. The air quality is so poor that it is considered a public health emergency. The primary sources of air pollution are coal-fired power plants and vehicle emissions.
The high levels of pollution have contributed to an increase in respiratory illnesses, such as asthma and bronchitis. In addition, there is an increased risk of heart disease and cancer.
The government has been trying to address the issue by investing in renewable energy sources and promoting electric vehicles. However, the progress has been slow due to the lack of funds and the harsh winter conditions.

4. Kathmandu, Nepal
As the capital of Nepal, Kathmandu is home to more than 1.5 million people. Unfortunately, the city is located in a bowl-shaped valley in the Himalayas, making it susceptible to air pollution. According to the World Health Organization, Kathmandu is one of the most polluted cities in the world.
The primary sources of air pollution in Kathmandu are vehicles and industry. The high population density and lack of regulations also contribute to the pollution problem. In addition to air pollution, Kathmandu has a severe water pollution problem.
The government of Nepal is aware of the pollution problems in Kathmandu and is working on solutions. However, much more needs to be done to improve the quality of life for the people living in this city.

3.Faridabad, India
Faridabad, India, is one of the most polluted cities in the world. The city is located in the north Indian state of Haryana and is home to more than 2.5 million people. The high levels of air pollution in the city result from emissions from factories, automobiles, and coal-fired power plants. In addition, Faridabad is also affected by dust storms from the deserts in neighbouring Rajasthan.
The air quality in Faridabad is often worse than in Delhi, one of the most polluted cities globally. The particulate matter (PM) levels in Faridabad are often more than ten times higher than the World Health Organization’s (WHO) recommended limit. In addition, levels of sulphur dioxide and nitrogen dioxide are also high, which can cause respiratory problems and other health issues.

According to the latest World Health Organization (WHO) report, Tetovo, North Macedonia, is among the most polluted cities globally. The city is ranked number six, with an annual mean of PM2.5 of 39 μg/m3.
Tetovo’s high levels of air pollution are due to a combination of factors, including emissions from automobiles and factories and unfavourable meteorological conditions. In addition, the city’s location at the foot of a mountain range contributes to its high levels of air pollution.
In addition to Tetovo, other cities in the Balkans that rank among the most polluted in the world include Skopje, North Macedonia (ranked 7th), and Pristina, Kosovo (ranked 8th).
