The American Lung Association has given Duval County an “F” grade in air quality.
Breaking it down, the city scores an “F” in both the number of high ozone days and in particle pollution.
The ALA released its tenth annual “State of the Air” report, compiled after reviewing data from about 1,000 counties nationwide.
The worst air quality? It’s Los Angeles. By comparison, the ozone data for Los Angeles indicates a weighted average of 96.5. A failing grade is anything over a 3.3. Jacksonville rates a 7.0.
San Bernardino and Riverside, both just east of Los Angeles, have readings of around 130.
