One of the greatest hazards to the planet and for human health is air pollution. It’s caused by the mass amounts of carbon dioxide released into the air from automobiles, factories, refineries, air traffic, ships on the ocean and a variety of other things. Chemicals released in the air from processing plants, high levels of methane gas from decomposing plants and animal waste are also big contributors. The problem has reached epic proportions, and although there are still some regions in the world with a decent quality of air, there are other locations that trigger severe health crises in vulnerable people. Pollution is determined by the number of particulates, or tiny, microscopic particles measured in the air that we breathe. They’re usually too small to see unless you observe them from a distance as smog.
Global pollution is causing deaths at an alarming rate. The World Health Organization has weighed in on this and estimates that 50% of all of the pollution-related deaths in the world originate from poor air quality in India and in China. Stroke, heart disease, cancer, and other health issues are a result. In some areas, sensitive people must wear masks to filter out the PM2.5 and PM10 particles. PM2.5 refers to particulates in the air which are smaller than 2.5 micrometers, and PM10 is smaller than 10 micrometers. We’ve gathered the recent statistics on the measured and average amount of these particulates found in the air of the worst cities for these two types of pollution. The measurements of air quality are conducted annually by the World Health Organization. Here are the 20 most polluted cities in the world for 2019.
20. Ulaanbaatar, Mongolia PM5 Pollution: 9.2 micrograms
Ulaanbaatar is the twentieth most polluted city in the world as of the middle of 2019. The population of this city is 1.4 million people. Just 10 years ago this city was not included in the listing of the 500 most polluted cities, and it’s climbed up to the 20th position within a decade. The average annual PM10 pollution rating is 196.9 micrograms. Families have been known to relocate members of their clan to other nearby countries when their health becomes negatively impacted by the poor air quality in Ulaanbaatar.
19. Baoding, North China PM10 Pollution: PM2.5 Pollution: 93.0 micrograms
Baoding is a country that is located in the North part of China. The PM2.5 Pollution readings are the 19th highest in the world. The population of this city is 1.1 million. The average annual PM10 pollution reading is 147 micrograms per cubic meter, but there are still 18 cities that are worse. One of the biggest issues afflicting this city is the fact that coal is used in high quantities and this harms the quality of the air.
18. Ali Subah Al-Salem, Kuwait
The population of Ali Sabah is 42,000. The PM2.5 pollution averages 93.8 micrograms per cubic meter. There is an average yearly reading of 198.1 micrograms of PM10 pollution. If you think that this is bad, just wait until you learn about even higher concentrations of these particulates in other cities throughout the world.
17. Narayangonj, Bangladesh PM2.5 pollution: 94.2 micrograms
Narayangoni has a population of 543,000 citizens, not counting visitors to the city. The air quality is so bad that people are breathing in air that is contaminated with 94.2 micrograms of PM2.5 pollution per cubic meter with an average of 205 mg of PM10 pollution per cubic meter. A comparison with the readings taken in 2015 shows that the levels of PM2.5 have risen by just .2 mg, with the amount of PM10 pollution remaining at the same levels. Manufacturing plants are blamed for much of the pollution in this city.
16. Jodhpur, West India PM2.5 pollution: 97.8 micrograms
Jodhpur has a population of 1.3 million citizens The PM2.5 air pollution is nearly at 98 mg per cubic meter with the PM10 just over 180. The air quality has remained about the same over the past decade, but the city has risen from the 17th position to the 16th worst of all cities which are monitored for average pollution contamination. There is a serious lack of rainfall in this region and that is believed to be a contributing factor to the air quality.
15. Patiala, North India PM2.5 pollution: 101.2 micrograms
Patiala is a city in North India with a population of 510,000 citizens. Just over half a million people live in a city that has the 15th highest PM2.5 readings in the world today, with the PM10 count at 183.7 mg per cubic meter. This creates a health risk for persons suffering from chronic respiratory conditions.
14. Delta Region, Egypt PM2.5 pollution: 102.2 micrograms
The Delta Region in Egypt covers a large area with dense populations of people within the area where the Nile Delta is located. This is an important place for commerce and as such, a high amount of road traffic and businesses filling the air with carbon emissions. The population is 7.9 million persons and the PM10 pollution readings average a sickening 249 micrograms per cubic meter.
13. Jaipur, West India PM2.5 pollution: 104.6 micrograms
Jaipur is a city located within West India with a population of 3.5 million residents with an air contamination issue that has slightly improved. In 2015 the PM2.5 pollution was 105, showing a slight decrease, with the M10 was 103. The current PM10 readings are at 192.6 showing a slight decrease in the annual averages, however, it climbed from the 14th worst city for pollution to the 13th on the list.

Although the latter has shown a slight increase in PM10, The reduction of PM2.5 pollution particles has moved it from the 10th worst city in the world for pollution to the 11th spot.
10. Muzaffarpur, East India PM2.5 pollution: 120 micrograms
Muzaffarpur, East India is a city with a population of 439,000 residents. There has been little change in the overall measurements of air contamination over the past three years. The city previously occupied the spot of number 11 on the most polluted cities for 2016, however, it’s moved up to the 10th position. This tells us that one of the former cities has decreased in its pollution levels at a minimum. The average annual PM10 pollution particulates per cubic meter for the city has been measured at 220.9 micrograms. The air is unhealthy for the average person to breathe, but could be deadly for those suffering from respiratory ailments.

3. Pasakha, Bhutan PM2.5 pollution: 149.9 micrograms
Pasakha, Bhutan is a new inclusion to the list of the 20 most polluted cities in the world for 2019. This is likely to be because of recent efforts to monitor the health of the environment which were not previously conducted in the past. It’s not so much that the city has become more polluted recently, but rather that the readings were simply not recorded.
