Most Polluted Cities in the World 2024 Complete List of Countries with Rank

Most Polluted Cities in the World 2024- Most Polluted Cities in the World: Delhi has remained the most pollute city in the world for the fourth year running. The cities most exposed to poor air quality have been identified by the State of worldwide Air (SoGA) initiative’s worldwide air quality report. This SoGA report provides information on pollution levels in different cities worldwide.

The public may read these reports, which are an invaluable resource for journalists, people, practitioners, politicians, and scientists to take essential action against the harmful effects of pollution. According to the report, over 68% of the world’s population is expected to live in cities and breathe in urban air by the year 2050. Particularly in lower- and middle-income nations, this fast urbanization is causing serious health hazards because of increased emissions.

Most Polluted Cities in the World 2024

People that are looking for better jobs and lifestyles tend to gravitate toward urban areas. Nevertheless, increasing urbanization raises air pollution levels, which negatively impacts public health. As a result, ailments like respiratory disorders, respiratory infections, type 2 diabetes, and cardiovascular problems become more common. The effects of these illnesses raise the odds of early death. A healthy air quality is recommend by the World Health Organization (WHO) to have a concentration of 5 micrograms per cubic meter of fine particle pollution outdoors. Nevertheless, the air quality regulations in many major global cities do not satisfy these WHO requirements.

The data in the paper is derive from an extensive investigation of the health effects of exposure to air pollution. Data was gather from seven thousand cities between 2010 and 2019. Nitrogen dioxide (NO2), a gaseous pollutant mostly emitted by traffic-relate pollution, and ambient fine particulate matter (PM 2.5) are the two primary types of air pollutants include by the analysis.

In 2022, the Swiss company IQAir publish the “World Air Quality Report,” which reveale that India ranked seventh in the world for pollution. This is a worrying ranking. Compare to last year, when it was rank sixth, this was a drop. The concentration of PM 2.5, a pollutant that the scientific and medical sectors regularly monitor, was used to establish the ranking.

10. Buenos Aires, Argentina

Visitors to Buenos Aires are aware of the city’s vibrant life and culture, yet these attributes come at a cost. The city is the tenth most polluted in the world; its name means “fair winds.” But noise, not excessively harmful pollutants, is what the air is carrying. Approximately 15.6 million people call Buenos Aires home, making up over a third of the nation’s total population. Most of them are crammed into tall apartments that line many of the city’s lengthy avenues. All of this creates the ideal environment for noise to be greatly amplified.

Because of the extreme heat in the city, families and businesses are also forced to run their air conditioners at high levels for extended periods of time. When individuals eventually venture outside, they are met with the din of trains, construction sites, and traffic-clogged cars honking. Due in major part to the vast number of lit advertising signs and buildings with brilliant lights that are constantly on, Buenos Aires has the sixth worst light pollution of any city on Earth in addition to being the most polluted city in South America due to noise.

9. Varanasi, India

Since Varanasi is the birthplace of Buddhism and a sacred spot for followers of Hinduism and Jainism, it is commonly regarded as the spiritual capital of India. Additionally, the city ranks tenth globally in terms of pollution. Varanasi is not so much plagued by noise as it is by pollutants from industrial factories, heavy traffic, diesel generators, and open fires where the city’s many poor residents congregate to cook and stay warm. Varanasi’s home state of Uttar Pradesh, which is home to eighteen coal-fired power plants—the largest of which, the Karsada plant, can burn a whopping 44 tons of coal a day—exacerbates the city’s issues.

8. Patna, India

Like the other Indian towns on our list, Patna is an old city locate on the Ganges River’s southern bank. It suffers from severe air pollution. Throughout the city, massive dump sites are use to incinerate waste; one such site is 74 acres in size and is situate in the village of Ramachak Bairiya. To put it simply, it is the same as 42 football fields fill to the brim with trash and burn every day. There are many of these locations in Patna, and according to a 2020 news article, 72 of the 75 municipal wards in the city don’t even segregate waste.

Farmers in Patna contribute to the sour air by burning their fields to make way for the following crop cycle. Earlier, the Indian government launch a plan in 2021 to clean up Patna, but it hasn’t had much of an impact due to pollution from brick kilns, cars that emit pollutants, and the nearly nonexistent regulation of pollution from building sites.

7. Moscow, Russia

The capital of Russia does not have exceptionally bad air pollution on a worldwide scale, but it does have a serious issue with light pollution. With an excess light intensity 8.1 times the world average, Moscow does, in fact, have the greatest light pollution problem of any city on Earth. The cacophony produce by the metropolis closely echoes the dazzling lights. The local Environmental Health Service said in 2007 that 70% of the city was in a “zone of noise discomfort,” which is a persistent issue. There is little proof that those who break noise ordinances ever get the penalties that are suppose to be applied.

6. Gaya, India

Moving forward, our travels will only take us across India and Pakistan, beginning with Gaya, the sixth-rank Indian city. Gaya is on our list because of “fine particulate matter,” a kind of air pollution that, at high enough concentrations, is harmful to human health. It’s indicated as:

PM2.5: Particles with a diameter of no more than 2.5 microns, which are mostly found in emissions from burning wood, oil, diesel fuel, and gasoline. PM10 particles, which have a diameter of no more than 10 microns, are present in the same emissions as PM2.5 but can also be found in dust from industrial sources, landfills, building sites, agricultural practices, wildfires, and burning garbage.

Gaya’s PM2.5 and PM10 levels have been found to be 14 and 13 times higher, respectively, than what is recommended by the World Health Organization (WHO). The primary causes of this are the uncheck sand mining, building, and stone-mining operations that have taken place in the region, which have significantly worsen the local ecology and air quality. In addition, Gaya is the sixth most polluting city in the world due to a combination of factors including outdate buses, diesel automobiles, excessive coal burning, and a lack of sewage treatment and proper disposal facilities.

5. Faridabad, India

India, Faridabad, which is near Delhi, is well known for manufacturing and exporting henna, a plant-base color use for temporary hair and body art. In addition, the city produces a wide range of other goods, many of which produce large amounts of greenhouse gases, including clothes, automobiles, refrigerators, air conditioners, syringes, and tires.

In addition to being jam-pack with old, diesel-power cars, the streets of Faridabad also wind around a lot of building sites and roadworks, which adds to the air pollution cause by fine particulate matter. To exacerbate the situation, garbage, rubber, and plastic are frequently burnt outside, creating deadly smoke plumes that cover entire neighborhoods.

4. Rawalpindi, Pakistan

Pakistan, which is now suffering from terrible floods that have submerged large portions of the nation, also has a serious pollution issue. In fact, it was recently shown that pollution plays a factor in 22% of all fatalities in Pakistan. There are very few green places to offset the dangerous pollutants release into the environment by oil refineries, marble industries, steel rolling mills, and leather tanneries.

In addition, the open burning of garbage, including dead plant materials and animal dung, and the toxic vapors from biomass fires are a source of discomfort for the local population. The levels of PM2.5 in the air have been found to be ten times higher than those recommend by the World Health Organization (WHO). PM10 levels are 21 times greater. As to IQAir, the severity of air pollution in Rawalpindian communities increases the risk of significant organ damage, heart disease, and various malignancies.

3. Kanpur, India

Thanks to the unfavorable record of having the highest PM2.5 concentration on Earth, the northern city of Kanpur comes in at number three on our list. Kanpur, which is locate in Uttar Pradesh, the most populous state in India, is home to an excessive number of coal-burning companies and a large number of people who heat their houses with dangerous biomass boilers.

“The state government does not have the mechanism to understand the sources of air pollution; how will they tackle it?” said Professor Sachchida Nand Tripathi, Head of the Indian Institute of Technology Kanpur’s Civil Engineering Department, in a Reuters interview.

2. Peshawar, Pakistan

With air pollution levels that high, Peshawar, the sixth-largest city in Pakistan, may rightfully claim the title of second most pollute city in the world. While the World Health Organization’s air quality criteria are met in terms of PM2.5 level, which is ten times higher, experts are more alarmed by the concentration of PM10, which is 26 times more than the recommend limit.

The numerous cars in Peshawar that run on diesel or subpar fuel are a contributing factor to these levels. Still, the 450 brick kilns that run nonstop all year round are the main cause of the terrible pollution in the city, not these fuels. The burning of rubber in brick kilns is known to release massive amounts of toxic fumes, which are so prevalent that many people living in Peshawar have different respiratory problems.

1. Delhi, India

Delhi is one of the most recognizable cities in the world, with a population double that of London. The WHO claims that it is also the most pollute. The air is so contaminate that, in 2020, during the Covid-19 lockdowns, the quality of the air improve to the point where residents saw clear blue sky for the first time in years.

The largest source of air pollution is thought to be crop burning, although there are other factors as well, such as large vehicle numbers, coal-powered generating plants, and industrial fires. In September, rice farmers forcibly burn their fields to make room for wheat, the next crop. Millions of tons of agricultural waste are burn, covering the entire city in a dense orange haze. The cycle repeats again before the quality of the air can even start to improve.

Conclusion

The most polluted cities in the world in 2024 continue to face significant challenges when it comes to air quality. These cities are grappling with high levels of air pollution, which have detrimental effects on the health and well-being of their residents. From heavy industrialization to vehicular emissions, there are various factors contributing to the poor air quality in these cities. However, efforts are being made to address this issue through stricter regulations and initiatives aimed at reducing pollution levels. It is crucial for governments, organizations, and individuals to work together towards sustainable solutions that will improve the air quality and overall livability of these cities.
