Key Findings
How Is Air Quality Calculated?
Pollution is a significant problem in the world today, and it is important to pay attention to the quality of the air in the local area. That is why the air quality index, usually shortened to AQI, is so important. This gives everyone an idea of how clean the air is in the local area. Typically, the air quality is calculated based on the particulate matter that is in the air. The more contaminants there are in the air, the higher the air quality index will be. On the other hand, if the air does not have a lot of pollution, then the air quality index will be lower. The air quality index is particularly important for people who suffer from chronic respiratory conditions, as their symptoms might get worse than the air quality gets worse.
What Cities in the United States Have the Highest Air Quality?
There are a handful of cities in the United States that have exceptional air quality. For example, Wilmington North Carolina, which sits on the Atlantic coast, has some of the cleanest air in the Southeast. In addition, the Palm Bay Area in Florida has very clean air.
There are some cities in the northeast that have very clean air as well. For example, Bangor, Maine is known for having clean air. Burlington, located in Vermont, also has very clean air.
Finally, cities that are far away from commercial centers tend to have cleaner air. Therefore, it should come as no surprise that Honolulu, located in Hawaii, also has very clean air.
Which Cities Have Polluted Air?
There are several cities that have filled the air, but the most polluted cities in the world are not located in the United States. Lahore, which is located in Pakistan, has extremely filthy air. There are also a number of cities in India that have very dirty air as well. A few examples include Hapur, Delhi, and Muzaffarnagar. All of these cities have very dirty air, and the government is trying to do more to clean up the air. In addition, there are some scattered cities in Mexico, including Mexico City, that have very dirty as well.
Does China Have Dirty Air?
Yes, there are multiple cities in China that have very dirty air. Even though China has done some work during the past few years to improve its air quality, it still has a long way to go. For example, Beijing is known for having very dirty air. It can get particularly dirty during the summer, when the temperature begins to warm up outside. Shanghai is also known for having very dirty air. People who live in these cities need to keep an eye on the air quality index. When the air quality gets particularly bad, it might be a good idea to wear a filtration device outside. That way, people don't have to worry about breathing particulate matter into their lungs, which can make them sick in just a few days.
