10 US Cities That have Worst & Good Air quality
According to an American Lung Association research, more than 40% of Americans, or approximately 135 million people, lived in areas with harmful levels of ozone or particle pollution, with cities in the West and Southwest dominating the list.

According to the Environmental Protection Agency, inhaling even small ozone levels can result in throat discomfort, chest pain, coughing, and shortness of breath. Additionally, it can make chronic respiratory conditions like asthma worse and impair the body's immunity against infections.

If you want to choose any city for residency in the USA, you need to examine first which city is not good for you as having bad air quality. This video will cover 5 US cities with the most polluted air quality in this video. Also, we'll examine the 5 best US cities with cleaner air quality. So, let's dive deep into the other video and explore this amazing knowledge.
5 Us cities with bad air quality:
The following cities have the worst ozone pollution:

Los Angeles-Long Beach, California:
According to a recent assessment from the American Lung Association, the Los Angeles-Long Beach metropolitan region has some of the worst air pollutions in the country.
With probably 180 days of high ozone pollution during 2018, LA-Long Beach has the worst smog pollution. In the sense of ozone, yearly particle pollution, and 24-hour particle pollution, the LA-Long Beach metro region scored poor marks. Out of more than Two hundred metropolitan regions nationwide, it came first, eighth, and fifth, respectively.
Visalia California:
The American Lung Association ranked Visalia as the second-most polluted city in the nation, only behind Los Angeles, in its 2019 study. In 2015–17, according to the same assessment, Visalia had the fourth-worst levels of year-round particle pollution.
But the Porterville-Visalia region has consistently ranked among the top five most polluted regions for more than ten years. Porterville-Visalia ranked third for smog pollution and fourth for year-round particle pollution in the association's 2009 assessment.
Fresno-Madera-Hanford, California:
Fresno has consistently been among the worst for ozone and particle pollution in the US. The Fresno region (including Madera and Hanford) came in second for both short-term and year-round particle pollution in the 2021 study, published earlier this month. PM2.28, or fine particles, are those.
Numerous elements, such as truck traffic and automobile emissions from commuters, tourists, and visitors, impact Fresno's air quality. Industrial emissions from business and farming activities. Dust and agricultural PM10.
Particulate pollution, such as PM2.5, from commuter cars, logistics and vehicles like semi-trucks, and farming equipment combined with recurring levels of dust and vapours from farming and pesticide use along with geography that traps pollutants in the low elevations of the Central Valley.
Phoenix-Mesa, Arizona:
Mesa is extensively involved in producing and building various products, including satellites, missiles, aircraft, and other items with similar aviation or technological focus.
The large-scale movement of people and the large-scale import and export of industrial goods are two sources of pollution that impact Mesa's air quality. Despite this inevitable change in the air quality, the city nonetheless receives a good pollution reading.
Vehicle emissions are among the most common sources of ambient pollution globally and continue to contribute significantly to pollution accumulations in Mesa. Large volumes of harmful particulate matter and chemical pollutants may be released by cars and other small vehicles. These gases are especially toxic when they build up over regions with a lot of traffic.
Bakersfield, California:
According to Benjamin, the mountains surrounding the Bakersfield region tend to hold onto air pollution, preventing it from dispersing. According to Meredith Kurpius from the Environmental Protection Agency, Bakersfield's location at the southern end of the San Joaquin Valley basin, where trends indicate worsening air quality, is the reason for this. Out of 203 metropolitan areas, Bakersfield was ranked first for yearly particle pollution in the 2020 Air Quality Report.
Due to the area's high-emission businesses (including agricultural and the generation of fossil-fuel-based electricity), rising household emissions, and its geographical and climatic circumstances, which allow dirty air to become trapped in the valley, Bakersfield has significant levels of air pollution.
