Lung Association Report: Miami/Fort Lauderdale Area Receives Mixed Grades for Air Quality

Report reveals improved ozone pollution, but worse year-round particle pollution for Miami/Fort Lauderdale metro area

This year’s “State of the Air” report from the American Lung Association finds that the Miami/Fort Lauderdale area received mixed grades for air quality. The area’s ozone pollution improved, but it saw higher year-round particle pollution. See the full report at

The Lung Association’s annual air quality “report card” tracks and grades Americans’ exposure to unhealthful levels of particle pollution (also known as soot) and ozone (smog) over a three-year period – this year’s report covers 2017-2019.

“While ozone pollution is improving in the area, the levels of year-round particle pollution seen in the Miami/Fort Lauderdale area can harm the health of all of our residents, but place our children, older adults and people living with lung disease particularly at risk,” said Ashley Lyerly, the director of advocacy for the Lung Association. “Fortunately, the area was ranked as one of the cleanest cities for short-term particle pollution, which means that there were no unhealthy days for this common pollutant.”

Ozone Pollution in Miami/Fort Lauderdale
Compared to the 2020 report, Miami/Fort Lauderdale experienced fewer unhealthy days of high ozone in this year’s report. “State of the Air” found that Miami/Fort Lauderdale area had a weighted average of 2.0 days (a C grade) of unhealthy ozone levels for 2017-2019. This has improved from the “D” grade that the area received in last year’s report. 

Particle Pollution in Miami/Fort Lauderdale
Compared to the 2020 report, “State of the Air” report found that year-round particle pollution levels in Miami/Fort Lauderdale were higher in this year’s report. The area was ranked 43rd most polluted for year-round particle pollution, which is significantly worse than its ranking of 116th last year. The report also tracked short-term spikes in particle pollution, which can be extremely dangerous and even lethal. The Miami/Fort Lauderdale area was ranked as one of the cleanest cities for short-term particle pollution, which means that there were no unhealthy air quality days for particle pollution.

The “State of the Air” report found that nationwide, more than 4 in 10 people (135 million) lived with polluted air, placing their health and lives at risk. In Miami/Fort Lauderdale, year-round particle pollution placed its residents at risk, including those who are more vulnerable to the effects of air pollution, such as older adults, children and people with a lung disease. The report also shows that people of color were 61% more likely to live in a county with unhealthy air than white people, and three times more likely to live in a county that failed all three air quality grades. The report also finds that climate change made air quality worse and harder to clean up.

The report analyzes particle pollution in two ways: average annual levels and short-term spikes. Both ozone and particle pollution can cause premature death and other serious health effects such as asthma attacks and cardiovascular damage and are linked to developmental and reproductive harm. Particle pollution can also cause lung cancer.
