Bay Area Air Quality Among Worst In Nation

Bay Area Air Quality Among Worst In Nation

As an industrial hygienist it came as a surprise that the American Lung Association recently ranked Bay Area air quality among worst in nation for air pollution and particulates. Unhealthy levels of pollution were found in numerous parts of the country, but the San Francisco Bay Area was ranked sixth in the list of most polluted areas in the country.

Use the American Lung Association city tracker to find air pollution facts for your Bay Area city and county.

Air quality and air pollution clearly vary by city and county.

What Bay Area counties have bad air quality?

Not only does Bay Area air quality vary dramatically from county-to-county, but the degree of separation between counties is dramatic. For instance the following counties received an “F” grade indicating unhealthy levels of pollution:

  • Alameda
  • Contra Costa
  • Sacramento
  • San Joaquin
  • Santa Clara

What Bay Area counties have the best air quality?

While these Bay Area Counties ranked very well for air quality, receiving an “A” grade from the American Lung Association:

  • Marin
  • Mendocino
  • Monterey
  • Napa
  • San Francisco
  • Santa Cruz
  • Sonoma

 

That is as dramatic a continuum as you can imagine. This in part shows how much microclimates, impacts of climate change and road traffic, and wind patterns of the Bay Area impact local air pollution. San Mateo county was given a “B” by the American Lung Association, and Solono was given a “C.” These grades apply toward “high ozone days,” and an entirely different set of grades is available for “particle pollution.” There are differences between the two sets of data. For example, Marin County gets a “C” when it comes to particle pollution but an “A” when it comes to high ozone days.
