It's getting more difficult to find cities with clean air to breathe. With the number of automobiles on the road, jets in the air, and factories pumping pollutants into the environment, our bigger cities are becoming places which foster a host of respiratory and other ailments. In some cities, vulnerable citizens are even forced to wear face masks to prevent asthma attacks. Even though there is currently a global effort to cut down on the carbon, methane, and other toxic emissions going into the air, the epidemic of polluted cities is spreading and the World Health Organization has even ranked our cities in accordance with the hazard levels in the air. Here are the 20 worst cities with the worst air quality in the world, according to 2019 statistics.
20. Ulaanbaatar, Mongolia
The city of Ulaanbaatar, in Mongolia's air quality, is monitored on a constant basis. The population is 1.4 million and it is ranked as having the 20th worst air quality in the world. When measured in annual pollution rates, it averages 196.9 micrograms of MP10 pollution per cubic meter, and 92.2 micrograms of PM2.5 pollution per cubic meter. The city has climbed up one position on the list since 2018, which means that the problem is not getting any better, but rather, it is intensifying.
19. Baoding, North China
Baoding which is located in North China has a population of 1.1 million people. The PM2.5 pollution rates are 93.0 micrograms per cubic meter with an annual average of 147.0 micrograms of MP10 pollution per cubic meter. Since the ranking in 2016, the air quality in Baoding has not improved, but it has not gotten any worse either. It's holding its own in maintaining a steady level of unhealthy air.
18. Ali Subah Al Salem, Kuwait
This Kuwaiti city has a smaller population of just 42,000, but it is the 18th worst to live in with regards to air quality. Testing reveals tht the annual MP2.5 pollution is at 93.8 micrograms on average, with the PM10 pollution at 198.1 micrograms. The more recent averages move the country of Kuwait from having a city ranked as the 44th worst to the 18th, which tells us that there is a seriously worsening issue with air quality that must be addressed in the near future.
17. Narayangonj, Bangladesh
Narayangonj has a large population of 543,000. The average PM2.5 pollution per year is at 94.2 micrograms per cubic meter. The PM10 pollution readings for this year have averaged 205.0 micrograms, In 2015, the city was ranked as the 18th worst city in the world for its poor air quality, so the current ranking shows that they are making some small improvements and moving down on the list, but more needs to be done for the sake of the citizens.
16. Jodhpur, West India
Jodhpur is a large city in West India with a population of 1.3 million people. The annual PM2.5 pollution reading per cubic meter averages 97.8 micrograms with the PM10 pollution at 180.2 micrograms per cubic meter. Jodhpur was previously number 17 in 2016, and this shows that the air quality is worsening, as they have climbed up one position.
15. Patiala, North India
Patiala has a population of 510,000. It averages a PM2.5 pollution reading of 101.2 micrograms per cubic meter annually, with a PM10 pollution reading of 183.7 micrograms per cubic meter.

There are high concentrations of atmospheric pollutants which collectively referred to as a "Black Cloud" cover, attributed to local emissions from vehicle emissions, farmers burning their crops and other local emissions from commercial businesses.
13. Jaipur, West India
Jaipur has a population of 3.5 million people. The annual PM2.5 pollution rates are at 104.6 micrograms per cubic meter, with the PM10 pollution figures at 192.6 micrograms per cubic meter on average. Jaipur was previously number fourteen on the cities with the worst air list for 2016, showing that it's joining nearby larger cities in the issue of worsening air quality over time.
12. Greater Cairo, Egypt
The population in Greater Cairo is 18.8 million. This area is two positions worse than the neighboring Delta Region of the country with an average PM2.5 pollution reading of 116.6 micrograms per cubic meter on average within a year's time. The PM10 pollution statistics show this type of air contamination is at 284.0 micrograms per cubic meter. As with the Delta Region, the "Black Cloud" pollution is a dominant feature of the issues, and it shares the same contributing factors to the problem.

How these cities were ranked
The World Health Organization has maintained statistics of constant monitoring of air quality and compiled a listing of the cities ranked in accordance with the number of pollution particles present in the air per cubic meter for two types of pollution, notated as PM2.5 pollution and PM10 pollution. Comparisons with statistics maintained from as far back as 2015/2016 show changes in air quality over the past three years and the inclusion of new cities with worsening air quality. Concentrations of these pollutants are measured and the levels are averaged over a time period of one year. The most common particles found in the air include concentrations of sulfur dioxide, carbon monoxide, ozone and nitrogen oxides.
What does this tell us about the condition of the environment?
What we can take away from this report is that there is a serious problem with the worst air pollution happening in South Asia, in particular, in the country of India. We're seeing other countries such as Egypt weighing in with increasingly poor air quality, and although some cities are making slight improvements, it's not enough to take them off the list. High populations, vehicle emissions, fumes and releases from factories, the use of aerosols and methane emissions are among the contributing factors to the problem. These are the worst cities, and although the problem is not as pronounced, the air in Southeast Asia is also highly polluted, but China is taking measures to cut down on air pollution. By comparison, the United States and Canada have relatively good air quality, but recent wildfires have raised the level of pollutants in the air that the populations are breathing in. There is little that can be done to alter the natural catastrophes brought about by changing climate conditions, hastening the incidence of wildfires, but we can cut down on the burning of fossil fuels. This, in turn, may help to decrease the effects upon the climate.
