Millions of people across the globe stayed indoors for more than a year due to the coronavirus pandemic. Many experts believed that the lack of vehicular traffic meant that air quality would significantly improve.
As it turns out, more than 100 million Americans are still breathing in heavily polluted air. In fact, according to a recent report by the American Lung Association, more than four in 10 Americans live with polluted air.
The report also revealed that air pollution hits communities of color the hardest. People of color are 61 percent more likely than white people to live in a county with unhealthy levels of air pollution.
People of color are also three times more likely to live in a county that failed all three air quality grades.
The report focused on two of the most widespread and dangerous air pollutants: ground-level ozone and fine particulate matter.
Researchers examined data collected by federal, state, local and tribal governments in 2017, 2018 and 2019. These are the years with the most recent quality-assured air pollution data.
Cities with the worst particle pollution year-round included Fairbanks, Alaska and several cities in California, including Los Angeles and Bakersfield. The researchers noted that California has consistently placed high in previous lists. This is surprising since California consistently produces more green energy than other states.
The researchers said high air pollution levels in California may be attributed to the shipping and trucking activities in the region. The mountain ranges in California also create “bowls” that can trap air pollution. Additionally, wildfires, which generate thick plumes of smoke, occur every year in California.
The report also showed that the warmer temperatures felt in recent years can make ground-level ozone more likely to form. Ground-level ozone forms when heat and sunlight react with pollutants emitted by cars, industrial plants and wildfire smoke. Without wind or rain, ground-level ozone can build up.
Long-term exposure to ground-level ozone or fine particulate matter can worsen respiratory problems, including bronchitis, emphysema and asthma. Ground-level ozone can also reduce lung function and cause inflammation of the lungs, while particle pollution can lead to death in people with heart problems.
On a positive note, individuals can take certain steps to reduce their exposure to polluted air. These include:
